Introduction to failure mode and effects analysis (fmea).

There are numerous high-profile examples of product recalls resulting from poorly designed products and/or processes. These failures are debated in the public forum with manufacturers, service providers and suppliers being depicted as incapable of providing a safe product. Failure Mode and Effects Analysis, or FMEA, is a methodology aimed at allowing organizations to anticipate failure during the design stage by identifying all of the possible failures in a design or manufacturing process.

Developed in the 1950s, FMEA was one of the earliest structured reliability improvement methods. Today it is still a highly effective method of lowering the possibility of failure.

What is Failure Mode and Effects Analysis (FMEA)

Failure Mode and Effects Analysis (FMEA) is a structured approach to discovering potential failures that may exist within the design of a product or process.

Failure modes are the ways in which a process can fail. Effects are the ways that these failures can lead to waste, defects or harmful outcomes for the customer. Failure Mode and Effects Analysis is designed to identify, prioritize and limit these failure modes.

FMEA is not a substitute for good engineering. Rather, it enhances good engineering by applying the knowledge and experience of a Cross Functional Team (CFT) to review the design progress of a product or process by assessing its risk of failure.

There are two broad categories of FMEA, Design FMEA (DFMEA) and Process FMEA (PFMEA) .

Design FMEA

Design FMEA (DFMEA) explores the possibility of product malfunctions, reduced product life, and safety and regulatory concerns derived from:

  • Material Properties
  • Interfaces with other components and/or systems
  • Engineering Noise: environments, user profile, degradation, systems interactions

Process FMEA

Process FMEA (PFMEA) discovers failure that impacts product quality, reduced reliability of the process, customer dissatisfaction, and safety or environmental hazards derived from:

  • Human Factors
  • Methods followed while processing
  • Materials used
  • Machines utilized
  • Measurement systems impact on acceptance
  • Environment Factors on process performance

Why Perform Failure Mode and Effects Analysis (FMEA)

Historically, the sooner a failure is discovered, the less it will cost. If a failure is discovered late in product development or launch, the impact is exponentially more devastating.

FMEA is one of many tools used to discover failure at its earliest possible point in product or process design. Discovering a failure early in Product Development (PD) using FMEA provides the benefits of:

  • Multiple choices for Mitigating the Risk
  • Higher capability of Verification and Validation of changes
  • Collaboration between design of the product and process
  • Improved Design for Manufacturing and Assembly (DFM/A)
  • Lower cost solutions
  • Legacy, Tribal Knowledge, and Standard Work utilization

Ultimately, this methodology is effective at identifying and correcting process failures early on so that you can avoid the nasty consequences of poor performance.

Late Failure Mode Discovery

When to Perform Failure Mode and Effects Analysis (FMEA)

There are several times at which it makes sense to perform a Failure Mode and Effects Analysis:

  • When you are designing a new product, process or service
  • When you are planning on performing an existing process in a different way
  • When you have a quality improvement goal for a specific process
  • When you need to understand and improve the failures of a process

In addition, it is advisable to perform an FMEA occasionally throughout the lifetime of a process. Quality and reliability must be consistently examined and improved for optimal results.

How to Perform Failure Mode and Effects Analysis (FMEA)

FMEA is performed in seven steps, with key activities at each step. The steps are separated to assure that only the appropriate team members for each step are required to be present. The FMEA approach used by Quality-One has been developed to avoid typical pitfalls which make the analysis slow and ineffective. The Quality-One Three Path Model allows for prioritization of activity and efficient use of team time.

There are Seven Steps to Developing an FMEA:

  • FMEA Pre-Work and Assemble the FMEA Team
  • Path 1 Development (Requirements through Severity Ranking)
  • Path 2 Development (Potential Causes and Prevention Controls through Occurrence Ranking)
  • Path 3 Development (Testing and Detection Controls through Detection Ranking)
  • Action Priority & Assignment
  • Actions Taken / Design Review
  • Re-ranking RPN & Closure

The Steps for conducting FMEA are as follows:

  • FMEA Pre-Work and Assembly of the FMEA Team

Pre-work involves the collection and creation of key documents. FMEA works smoothly through the development phases when an investigation of past failures and preparatory documents is performed from its onset. Preparatory documents may include:

  • Eight Disciplines of Problem Solving (8D)
  • Boundary/Block Diagram (For the DFMEA)
  • Parameter Diagram (For the DFMEA)
  • Process Flow Diagram (For the PFMEA)
  • Characteristics Matrix (For the PFMEA)

A pre-work Checklist is recommended for an efficient FMEA event. Checklist items may include:

  • Requirements to be included
  • Design and / or Process Assumptions
  • Preliminary Bill of Material / Components
  • Known causes from surrogate products
  • Potential causes from interfaces
  • Potential causes from design choices
  • Potential causes from noises and environments
  • Family or Baseline FMEA (Historical FMEA)
  • Past Test and Control Methods used on similar products
  • Path 1 Development- (Requirements through Severity Ranking)

Path 1 consists of inserting the functions, failure modes, effects of failure and Severity rankings. The pre-work documents assist in this task by taking information previously captured to populate the first few columns (depending on the worksheet selected) of the FMEA.

  • Wants, needs and desires translated
  • Specifications of a design
  • Government regulations
  • Program-specific requirements
  • Characteristics of product to be analyzed
  • Desired process outputs
  • Full function failure
  • Partial / degraded function failure
  • Intermittent function failure
  • Over function failure
  • Unintended function failure
  • Recommended Actions may be considered that impact the product or process design addressing Failure Modes on High Severity Rankings (Safety and Regulatory)
  • Path 2 Development – (Potential Causes and Prevention Controls through Occurrence Ranking)

Causes are selected from the design / process inputs or past failures and placed in the Cause column when applicable to a specific failure mode. The columns completed in Path 2 are:

  • Potential Causes / Mechanisms of Failure
  • Current Prevention Controls (i.e. standard work, previously successful designs, etc.)
  • Occurrence Rankings for each cause
  • Classification of Special Characteristics, if indicated
  • Actions are developed to address high risk Severity and Occurrence combinations, defined in the Quality-One Criticality Matrix
  • Path 3 Development- (Testing and Detection Controls through Detection Ranking)

Path 3 Development involves the addition of Detection Controls that verify that the design meets requirements (for Design FMEA) or cause and/or failure mode, if undetected, may reach a customer (for Process FMEA).

  • Detection Controls
  • Detection Ranking
  • Actions are determined to improve the controls if they are insufficient to the Risks determined in Paths 1 and 2. Recommended Actions should address weakness in the testing and/or control strategy.
  • Review and updates of the Design Verification Plan and Report (DVP&R) or Control Plans are also possible outcomes of Path 3.

The Actions that were previously determined in Paths 1, 2 or 3 are assigned a Risk Priority Number (RPN) for action follow-up.

RPN is calculated by multiplying the Severity, Occurrence and Detection Rankings for each potential failure / effect, cause and control combination. Actions should not be determined based on an RPN threshold value. This is done commonly and is a practice that leads to poor team behavior. The columns completed are:

  • Review Recommended Actions and assign RPN for additional follow-up
  • Assign Actions to appropriate personnel
  • Assign action due dates

FMEA Actions are closed when counter measures have been taken and are successful at reducing risk. The purpose of an FMEA is to discover and mitigate risk. FMEAs which do not find risk are considered to be weak and non-value added. Effort of the team did not produce improvement and therefore time was wasted in the analysis.

  • Re-Ranking RPN and Closure

After successful confirmation of Risk Mitigation Actions, the Core Team or Team Leader will re-rank the appropriate ranking value (Severity, Occurrence or Detection). The new rankings will be multiplied to attain the new RPN. The original RPN is compared to the revised RPN and the relative improvement to the design or process has been confirmed. Columns completed in Step 7:

  • Re-ranked Severity
  • Re-ranked Occurrence
  • Re-ranked Detection
  • Re-ranked RPN
  • Generate new Actions, repeating Step 5, until risk has been mitigated
  • Comparison of initial RPN and revised RPN

FMEA Document Analysis

Deciding when to take an action on the FMEA has historically been determined by RPN thresholds. Quality-One does not recommend the use of RPN thresholds for setting action targets. Such targets are believed to negatively change team behavior because teams select the lowest numbers to get below the threshold and not actual risk, requiring mitigation.

The analysis of an FMEA should include multiple level considerations, including:

  • Severity of 9 / 10 or Safety and Regulatory alone (Failure Mode Actions)
  • Criticality combinations for Severity and Occurrence (Cause Actions)
  • Detection Controls (Test and Control Plan Actions)

When completed, Actions move the risk from its current position in the Quality-One FMEA Criticality Matrix to a lower risk position.

RPN Action Priority

When risk is determined to be unacceptable, Quality-One recommends a priority of action to be applied as follows:

  • Failure Mode (Only Severity of 9 or 10)
  • Causes with High Occurrence
  • Increase Tolerance (Tolerance Design)
  • Reduce Variation of the Process ( Statistical Process Control and Process Capability)
  • Mistake Proofing of the tooling or process
  • Improve the inspection / evaluation techniques

FMEA Relationship to Problem Solving

The Failure Modes in a FMEA are equivalent to the Problem Statement or Problem Description in Problem Solving . Causes in a FMEA are equivalent to potential root causes in Problem Solving. Effects of failure in a FMEA are Problem Symptoms in Problem Solving. More examples of this relationship are:

  • The problem statements and descriptions are linked between both documents. Problem solving methods are completed faster by utilizing easy to locate, pre-brainstormed information from an FMEA.
  • Possible causes in an FMEA are immediately used to jump start Fishbone or Ishikawa diagrams. Brainstorming information that is already known is not a good use of time or resources.
  • Data collected from problem solving is placed into an FMEA for future planning of new products or process quality. This allows an FMEA to consider actual failures, categorized as failure modes and causes, making the FMEA more effective and complete.
  • The design or process controls in an FMEA are used in verifying the root cause and Permanent Corrective Action (PCA).
  • The FMEA and Problem Solving reconcile each failure and cause by cross documenting failure modes, problem statements and possible causes.

FMEA Example

This FMEA Example has one item with a progression through multiple recommended Actions. With each instance, the revised RPN has improved. The final RPN of 10 indicates the issue has been mitigated successfully. The new state should be captured as Standard Work.

Failure Mode and Effects Analysis

"Anything That Can Go Wrong, Will Go Wrong" Murphy's General Law

What is FMEA?

Failure Mode and Effects Analysis (FMEA) is a systematic approach for identifying probable failures in a system, product, or process, evaluating their impacts, and figuring out how to minimize or prevent them. FMEA is a proactive method that seeks to foresee future issues and deal with them in advance of happening rather than responding to them after the fact. Reliability, safety, and quality control are frequently addressed in engineering design through the FMEA process.

In order to identify probable failure modes, their consequences, and their causes, a team of experts conducting a basic FMEA process thoroughly reviews a system, product, or process. On the basis of severity, the likelihood of occurrence, and detectability, the team then assigns a rating to each probable failure mode. The possible failure modes are ranked according to importance using the information provided. The team then creates and puts into effect measures to avoid or minimize the most critical failure scenarios.

FMEA fosters a proactive approach to problem-solving, which is one of its main advantages. Organizations may avoid or reduce difficulties by spotting them in advance and taking action, thereby saving time and money. Exploring "what-if" scenarios is encouraged by the qualitative process of FMEA, which may be used to find probable failure modes that would not be apparent by other methods.

FMEA's ultimate objective is to limit or completely eradicate the likelihood of crucial failures. Organizations may enhance the dependability, safety, and quality of their goods and services, which will boost client happiness and loyalty by taking a systematic approach to identifying and resolving possible issues.

History Facts

In order to assess probable failures and their impact on military equipment, the US military created FMEA in the 1940s. FMEA was used by the military to reduce the risk of equipment failure during operations and to guarantee that it was dependable. 

The aerospace sector first used FMEA in the 1960s to assess possible risks and product failures, and it quickly became a crucial step in their design and production processes. FMEA was implemented by the automotive industry in the 1970s in order to assure the safety and dependability of their cars in light of the growing complexity of automotive systems.

In the 1980s, several sectors embraced FMEA as a reliable technique for spotting probable failures. During this time, the Society of Automotive Engineers (SAE) developed a standard approach for FMEA implementation that included best practices for applying FMEA across industries. A new standard known as Design FMEA (DFMEA), which is used exclusively for examining the risks and potential failures connected with product design, was released in 2008. A development of the conventional FMEA method, DFMEA concentrates on locating and preventing any flaws during the design stage itself.

The AIAG-VDA FMEA Harmonization Project, which sought to unify several FMEA standards and guides across sectors, gave FMEA a facelift in 2019. By removing redundancy and streamlining the technique, this initiative attempted to improve the FMEA process' efficiency and effectiveness.

FMEA Case: Order Fulfillment by Online Store

In this article,the FMEA process using the example of the order fulfillment process in an online store will be analyzed.

Define Scope and Objectives

First, the scope and purpose of the FMEA needs to be defined. This involves defining the product or process to be analyzed, the purpose of the analysis, and the team of experts who will conduct the analysis. It is important to note that the team should be truly cross-functional, i.e., with people with different knowledge of the process, product or service, and customer needs. That is, this process is not conducted by only one team member (e.g., a business analyst or project manager), but almost all stakeholders, both internal and external, should participate in it.

For the case study at hand, we first describe what exactly will be investigated, namely the process of receiving, selecting and packing, as well as delivering orders. The next section shows why this is done, for what purpose. It also identifies a cross-functional team that will conduct this analysis.

Identify potential failures and effects

Next, all potential failure modes and their impact should be identified. This can be done by brainstorming, reviewing historical data, or using other tools such as fault tree analysis, for example.

Evaluate Severity, Occurrence, and Detectability

Once the potential failures have been identified, it is necessary to assess the severity,  occurrence, and detectability of each failure. Severity is the seriousness of the effect of a failure mode on the customer or end user. Occurrence is the probability or frequency of the failure mode occurring. And detectability is  the ability of current controls or systems to detect the failure mode before it reaches the customer or end user. The scores are quantified by the expert group identified in the first step.

Scales for Evaluation

A set of scales is typically used to evaluate the severity, frequency of occurrence, and detectability of potential failures during an FMEA. These scales are used to assign numerical ratings to each failure mode, which allows for the calculation of a risk priority number (RPN).

Some of the scales used include:

  • Severity. A scale from 1 to 10, where 1 is the least serious and 10 is the most serious. The severity rating is based on the potential impact of the failure mode on the client or end user.
  • Occurrence. A scale from 1 to 10, where 1 is the least likely and 10 is the most likely. The frequency rating is based on the probability of the failure mode occurring.
  • Detectability. A scale from 1 to 10, where 1 is the most detectable and 10 is the least detectable. The detectability score is based on the ease of detecting the failure mode before it causes a problem.

Figure 2 - Scales for Evaluation

Figure 2 - Scales for Evaluation 

Risk Calculation — Risk Priority Number (RPN)

Next, the risk priority number (RPN) for each failure mode needs to be calculated. The RPN is calculated by multiplying the severity, frequency, and detectability scores. This gives a numerical value that helps prioritize which failures should be addressed first. Regulation FMEA documents provide the following templates for the final risk priority assessment.

Figure 3 - RPN Calculation

Figure 3 - RPN Calculation

It is important to note that the RPN is not a definitive assessment of failures. It is simply a tool to help prioritize which ones should be addressed first. The FMEA team should use their judgment and experience to determine which failures are the most critical.

Identify and Implement Corrective Actions

Once the RPN is calculated:

  • Identify potential corrective actions for high-risk failure modes based on RPN values and other relevant factors.
  • Prioritize corrective actions based on feasibility, cost, and potential impact on customer satisfaction and revenue.
  • Assign responsibility for implementing corrective actions and establish timelines for completion.

There is an unofficial rule that if a failure mode has a low priority, then corrective actions for it are not carried out or are carried out last.

Verify Effectiveness of Corrective Actions

Finally, it is necessary to verify the effectiveness of the corrective measures taken. This step involves:

  • Monitoring of the implementation of corrective actions and verify their effectiveness in reducing the risk of high-priority failure modes.
  • Establishing a plan for ongoing monitoring and measurement to ensure sustained effectiveness of corrective actions.
  • Communicating the results of corrective action verification to relevant stakeholders and update the FMEA analysis as necessary.

It's essential to remember that FMEA is an ongoing process and should be constantly reviewed and updated as new information becomes available.

FMEA Key Principles

So, the key principles, the FMEA ideology, may now be defined, which include:

  • Prevention is better than detection. FMEA aims to identify potential failures before they occur, so that proactive measures can be taken to prevent them from happening in the first place. This approach is more effective and efficient than trying to detect and fix problems after they have occurred.
  • Systematic approach. FMEA is a systematic approach that involves a team-based approach to identify potential failure modes, their causes, and their effects on the system. This approach helps ensure that all potential failure modes are identified and analyzed.
  • Risk prioritization. FMEA uses a risk-based approach to prioritize potential failures based on their severity, occurrence, and detectability. This helps focus resources on the most critical failure modes and enables effective risk management.
  • Continuous improvement. FMEA is an iterative process that is used to continuously improve products, processes, and services. The results of FMEA can be used to inform design improvements, process changes, and other corrective actions to reduce the risk of failures.
  • Cross-functional collaboration. FMEA requires collaboration between different functions and departments within an organization to ensure that all potential failure modes are identified and analyzed. This collaboration also helps ensure that corrective actions are implemented effectively.
  • Documentation. FMEA results should be documented, including the identified failure modes, their causes and effects, and the recommended corrective actions. This documentation helps ensure that the knowledge gained through the FMEA process is retained and can be used to inform future improvements.

By adhering to these key principles, FMEA assists businesses in identifying and mitigating possible failures, improving product quality, dependability, and lowering expenses related to product recalls, warranty claims, and customer complaints.

FMEA Advantages & Disadvantages

Here are some of its Advantages and Disadvantages: Advantages:

  • Early identification of potential failures . Prior to actual problems developing, FMEA can assist in identifying possible issues throughout the design or production phase. Early detection of possible issues makes it simpler and less expensive to fix them.
  • Improved product/process design. FMEA may assist in raising the overall quality of the finished product by spotting possible issues early in the design or production process.
  • Improved communication. Different stakeholders must be involved in the risk management process as a result of FMEA, which can enhance their interaction and cooperation.
  • Cost-effective. Costs related to the discovery and repair of failures, warranty claims, and recalls can be decreased with the aid of FMEA.

Disadvantages :

  • Time-consuming. FMEA is a comprehensive and time-consuming procedure that needs a lot of work and resources to complete.
  • Limited scope. The effectiveness of an FMEA depends on the information available at the time it is conducted. It cannot plan for unforeseen or unpredictable threats.
  • Over-reliance on subjective assessments. Since FMEA calls for the use of expert opinion and assumptions, the risk assessment may become biased and vulnerable to subjectivity.
  • Lack of context. FMEA might not catch every possible failure mode, particularly if the procedure is hurried or the analysts lack the necessary training or expertise.

FMEA Modifications & Extensions

This process is often not used in its raw form in practice. Over the years, the FMEA process has undergone various modifications and extensions. Some common examples are:

  • FMECA (Failure Mode, Effects, and Criticality Analysis) is an extension of FMEA that adds a stage for determining the criticality or severity of each failure mode based on a combination of occurrence, detectability, and consequences. Prioritizing the most important failure modes that need urgent attention and mitigation is made easier by the criticality analysis. In industries and safety-critical systems where failure has serious repercussions, FMECA is frequently employed.
  • IME(C)A (Intrusion Modes and Effects (and Criticality) Analysis) is a risk assessment approach used to analyze the security and resilience of physical protection systems (PPS) against intrusion attempts by attackers. IMECA is frequently employed in high-security buildings where security breaches might have serious repercussions, such as nuclear power plants, military sites, and government structures.
  • Process FMEA is a FMEA variant that concentrates on examining probable failure modes in a manufacturing or production process as opposed to a system or a product. Process FMEA assists in identifying process-related risks that may have an impact on the process' quality, effectiveness, or productivity as well as developing corrective measures to avert or lessen such risks.
  • Design FMEA examines probable failure modes at the design stage of a system or product rather than during the manufacturing or production process. Design FMEA assists in identifying design-related risks that may have an impact on the functionality, safety, or dependability of the system or product and in developing design modifications or enhancements to eliminate or reduce such risks.
  • Software FMEA is applicable to software development initiatives.It aids in identifying possible failure modes during the phases of software design, coding, testing, and deployment and assists in the development of mitigating tactics to eliminate or minimize such risks. When software is essential to a product's performance and safety, such as in the automotive, aerospace, and medical device sectors, software FMEA is frequently utilized.

Why FMEA is still relevant today

Despite being around for over 70 years, FMEA is still a relevant and valuable tool for many industries. As products and processes become increasingly complex, the need for proactive risk management is becoming increasingly important. FMEA is still relevant today for several reasons:

  • Risk management. FMEA helps organizations to identify and mitigate potential risks associated with a product, process, or system. It helps to identify failure modes and their impact on the system, as well as to determine the likelihood of their occurrence
  • Quality improvement. FMEA can be used to improve the quality of products, processes, and systems by identifying potential issues and taking proactive steps to prevent them from occurring. This can help to reduce defects, increase customer satisfaction, and improve overall product reliability.
  • Regulatory compliance. Many industries, such as healthcare and automotive, require FMEA as part of their regulatory compliance requirements. FMEA helps to ensure that products and processes meet the necessary safety and quality standards.
  • Cost savings. By identifying potential issues early on in the development process, FMEA can help organizations to avoid costly mistakes and rework. This can lead to significant cost savings in the long run.

In summary, FMEA is a powerful tool that can help organizations prevent potential failures before they happen, ensuring that they are prepared for anything that could go wrong.

Failure Mode and Effects Analysis (FMEA)

Spotting problems before a solution is implemented.

By the Mind Tools Content Team

an fmea is primarily considered a problem solving tool

When things go badly wrong, it's easy to say with hindsight, "We should have known that would happen."And, with a little foresight, perhaps, problems could have been avoided if only someone had asked "What Could Go Wrong?"

By looking at all the things that could possibly go wrong at design stage, you can cheaply solve problems that would otherwise take vast effort and expense to correct, if left until the solution has been deployed in the field. Failure Modes and Effects Analysis (FMEA) helps you do this.

More than this, FMEA provides a useful approach for reviewing existing processes or systems, so that problems with these can be identified and eliminated.

Understanding FMEA

FMEA was originally known as Failure Mode, Effects, and Criticality Analysis (FMECA), and was first published in 1949 by the U.S. Department of Defense. FMEA grew out of systems engineering, and is a widely-used tool for quality control. It builds on tools like Risk Analysis and Cause and Effect Analysis to try to predict failures before they happen. Originally used in product development, it is also effective in improving the design of business processes and systems.

When using FMEA, you start by looking in detail at the proposed solution (see the tip box below) and then you identify systematically all of the points where it could fail. Once these potential failures have been identified, you rate the potential consequences of each according to:

Severity – how critical is the failure?

Occurrence – how likely is the failure to happen, detection – how easy will it be to detect the failure.

Using these rankings, you then identify the most serious threats, and then alter the design to eliminate or minimize the likelihood of the failure you identified.

Once you've redesigned your solution, it's worth repeating the FMEA to ensure that new potential points of failure have not been introduced into the design.

When using FMEA, it can often be best to draw expert team members from a wide variety of functions, so that you can look at the proposed solution from different angles. The purpose of FMEA is to uncover and assess potential failures, therefore the more thorough the investigation, the more useful the analysis.

There are a range of tools that you can use to map out the solution you want to examine, and the best tool to use will depend on the type of solution you're looking at. Among the tools you may want to consider using are Flow Charts , Swim Lane Diagrams , Systems Diagrams , or Value Chain Analysis .

How to Use Failure Modes and Effects Analysis

The best way of understanding FMEA is to use an example. Let's use it to look at a proposal for a simple payroll process.

Identify the solution, system or process you're looking at and, if appropriate, the main issue you want to investigate. List the critical elements, in a logical (for example, chronological) order.

Proposed Payroll Process – Key System Elements:

  • Hourly time sheet tally
  • Vacation pay calculation
  • Overtime calculation

Develop a flow chart to map the solution or process, and the interactions between its various parts.

Step Three:

Download our FMEA Matrix template . Use this template to work through each element in this process in turn.

For each element in the process, use brainstorming or carry out a risk analysis to identify the potential failures that may occur. Enter the ways that the solution or process can fail in the Failure Mode column of the FMEA Matrix.

  • Submit time sheet – employees fail to submit time sheets.
  • Submit time sheet – employees enter poor quality data on time sheets.
  • Submit time sheet – employee uses incorrect analysis codes.
  • Enter hours – human error in data entry.
  • Vacation pay calculated – human error in setting up formulae.
  • Vacation pay calculated – look-up tables not maintained.
  • And so on...

For each potential failure, identify the consequences of the failure.

  • Submit time sheet – employees fail to submit time sheets – under-billing of clients, non-payment of wages to employees
  • Submit time sheet – employees entering poor quality data on time sheets – clients incorrectly billed, unreliable management information
  • Submit time sheet – employee uses incorrect analysis codes – unreliable management information
  • Enter hours – human error in data entry – underpayment or overpayment of wages
  • Vacation pay calculated – human error in setting up formulae – significant and systematic overpayment or underpayment of wages

For each potential failure in the system, rank Severity, Occurrence and Detection using the following scales:

5 – Very High (huge losses that threaten company viability) 4 – High (large losses, company is still operable) 3 – Moderate (losses exist, can be remedied) 2 – Minor (loss is minimal, quite insignificant) 1 – Low (no effect)

5 – Very High (must be addressed immediately, will happen very often) 4 – High (will cause frequent issues, will happen often) 3 – Moderate (will cause sporadic issues, will happen occasionally) 2 – Minor (issue will be few and far between, will happen quite infrequently) 1 – Low (issues unlikely, not likely to ever happen)

5 – Very Difficult 4 – Difficult 3 – Somewhat Easy 2 – Easy 1 – Very Easy

In our example, the potential failure of the vacation pay calculation may be ranked as:

  • Severity 4 – If undetected, overpayment of wages could lead to significant financial loss
  • Occurrence 5 – If it happens, it may happen very often
  • Detection 3 – Executives are likely to spot significant overpayment of wages!

Step Seven:

Calculate the Risk Priority Number (RPN) for each of the modes and effects by multiplying the 3 ratings (Severity x Occurrence x Detection).

In the example above, the RPN is 60. This is likely to be one of the most significant risk points in this process, and therefore needs to be managed.

Step Eight:

Now you are ready to brainstorm action plans and make recommendations to counter the potential threats you uncovered. This step is best completed in phases starting with the modes and effects that have the highest RPN – in other words, those that represent the greatest threat.

This is where the cross-functional teams comes in very useful again. By putting together the best team of people, you can reassure yourself that the action plan that is recommended is well rounded, practical, and a relatively easy sell to the people who will have to make it happen.

In our example, thorough testing of the formula may be mandated, and the formula may be locked so that it can't accidentally be changed.

Once you've modified the design for the proposed solution, repeat the Failure Mode and Effects Analysis process to review the design, and make sure that no additional potential failure points can be identified.

The objective here is to develop a solution that has a low overall RPN. Where the RPN is still high, go back and revamp your plan, as appropriate, to address the issues that still pose a high failure potential.

Failure Modes and Effects Analysis is a useful tool for uncovering possible points of failure that may be lurking within business processes and solutions, whether these are already in place within your company or are proposed for the future.

This technique is as applicable to business solutions and processes as it is to its original application, product design. Ultimately, proposals that have been scrutinized using FMEA are more likely to be successful. If these are projects that you're responsible for, then your projects' success is your own success.

FMEA: How to properly set up Failure Modes and Effects Analysis

an fmea is primarily considered a problem solving tool

You may work in development , logistics, manufacturing, or another type of business with critical machinery. No matter what field you are in, FMEA is a necessary tool for reducing your risk of system failures. Planning out FMEA can be challenging, so we created this comprehensive guide to running a failure modes and effects analysis.

  • What is FMEA?

FMEA (Failure Mode and Effects Analysis, also known as Failure Modes and Effects Analysis or Failure Mode Effects Analysis), is a procedure used to pinpoint where certain systems or machinery might fail. That way, your team can set up a plan to proactively fix those systems. By reviewing as many components and subsystems as possible, you can identify the system’s potential failure modes and their root causes.

FMEA’s structured approach helps you anticipate potential failures in the manufacturing or design of a product or process. FMEA has two broad categories: Design FMEA (DFMEA) and Process FMEA (PFMEA) .

Failures are errors or defects, and can be potential or actual. Failure modes are the ways a product or process fails. (In other words, what went wrong, and how.)

Failure effects are the ways these failures can lead to waste, defects, or harmful outcomes. These consequences could include user injury, machine or process malfunction, or poor product quality. The system failure could also affect other systems directly related to it. Effects analysis studies how failures impact different system components.

FMEA is a common tool used in engineering related to safety, quality, and reliability. The analysis can be qualitative or quantitative. By using inductive reasoning to assess failure risks in a process or product’s design and development, FMEA makes good engineering even better. Your team can use FMEA to evaluate and prevent possible failures by correcting early, rather than reactively—after failures have occurred.

FMEA enables you to identify and prioritize failures according to how serious their consequences are, how often they happen, and how easy they are to find. You can then act to limit or prevent failures, starting with the most serious ones. Find out more.

History of FMEA

Developed by reliability engineers in the late 1950s, FMEA was one of the earliest systematic approaches to analyzing failures and finding their potential causes. FMEA was created to study potential problems caused by malfunctioning military systems, and continues to be effective at discovering potential failures and evaluating system reliability. This allows you to correct and limit process failures early so you can avoid their negative impacts on your system.

Failure mode effects and criticality analysis (FMECA) is an extension of FMEA.

The added criticality analysis lets your team compare the likelihood of failure modes against the severity of their consequences. You can then focus fixes on failure modes with higher probability and more severe consequences, where the fixes can do the most good.

When should you use FMEA?

Ideally, you should begin using FMEA during the earliest conceptual design stages of a process or product, and then through the design or redesign process. Alternatively, you can try using this approach in these cases :

  • Before you develop control plans for a new or modified process, and for control before and during ongoing processes.
  • When you plan to apply an existing process or product in a new way.
  • When you want to improve the quality of an existing process or product.
  • For optimal results, you should always examine and improve quality and reliability throughout the life of the process or product.
  • FMEA greatly benefits business owners and workers

There are also major risks to not using it! Why should you use FMEA? Here are the main reasons people prefer implementing this approach:

Fewer repair costs

FMEA works to proactively repair equipment and systems. So instead of working a machine till it fails and increasing its probability of future breakage, you fix it when it’s most optimal. If the failure is discovered sooner, it costs less than it would later in product or process development, when the failure could be worse.

More uptime

A machine breaks, which slows your assembly line. This means you’re losing money! FMEA procedures allow your team to evaluate design in a straightforward, orderly way, and to identify failure points and system interface problems early. This makes such random breakdowns far less likely.

Greater safety for workers and users

Safety is always your #1 priority, but what if a machine has outdated parts? That could be risky not only for your workers and users but for your business itself. FMEA helps lower risk of injuries through improved design and proactive repair.

Multiple choices for reducing risk

FMEA empowers your team to troubleshoot during ongoing procedures, and to develop ways to monitor performance and locate faults. It’s a documented method that helps you analyze how new or changed designs or processes impact safety and success.

  • 5 industries that use FMEA regularly

FMEA is widely used across industries from software development to manufacturing to healthcare, throughout product or process life cycles. Whatever your business is, discovering failure points early on helps you improve safety and quality, satisfy customers, and save money.

Software development

FMEA can be applied to software development . This approach is usually implemented when the team wants to improve software quality, reduce Cost of Quality (CoQ), Cost of Poor Quality, (CoPQ) and defect density.

Manufacturing

The manufacturing industry counts on FMEA to anticipate and eliminate potential assembly and product failures sooner, and prevent expensive corrective actions later. This results in reliably high-quality products that satisfy industry customers.

Transport and logistics

They also rely on FMEA to empower them to deliver products reliably. The industry uses FMEA to evaluate logistics and supply chains in order to ensure high-quality service to customers.

This industry counts on FMEA as an effective tool for identifying parts of processes that most need improvement. Working preventatively helps reduce risk to both patients and staff.

Agriculture

The industry also relies on FMEA. It is used to assess risk to the environment, to manufacturing and machinery, and to product quality. This is important for environmental, ethical, and legal considerations.

  • Having trouble putting together an FMEA plan?

FMEA can be complicated to fully plan out, but with Miro’s FMEA template , it’s simple!

We recommend having the template in front of you as you read the rest of this blog post. That way you can fill it out with ease.

Determine your team’s general procedure steps. But first be sure to fully educate relevant team members on your organization’s specific standards for the system you are evaluating. For more about FMEA procedure, read this .

  • FMEA definitions to get you started

Use FMEA as a risk assessment tool to evaluate the severity, occurrence and detection of risks so you can prioritize the most urgent ones. Read on to learn what each term means. Each category has a scoring matrix with a scale from 1 to 10.

Severity number (S)

Severity numbers are ranked 1–10. Unlikely failures or low risks to the end customer are rated as 1, whereas 10 means a high likelihood of failure or high risk.

Probability of occurrence (O)

The probability of occurrence is how often this failure or problem happens. These are also ranked 1–10, so a failure happening every 3rd time a machine turns on could be rated a 10, while a failure happening every 500,000 times a machine turns on could be a 1 or 2.

Likelihood of detection (D)

The likelihood of detection, also ranked 1–10, shows whether or not you have systems in place to detect the failure. If you get an alert the second a failure happens, mark it as a 1, but if you never get alerts and instead find out on your own, rank it as a 10.

Risk Priority Number (RPN)

Your Risk Priority Number is a combination of the above three. To get your RPN, multiply severity number by probability of occurrence by likelihood of detection: RPN = S x O x D.

  • How to run a Failure Modes and Effects Analysis with Miro

Now you and your team are ready to begin using Miro’s easy FMEA Template. Simply follow the process steps below.

Step 1. Open up the FMEA Template

You can find the FMEA template in our library. Sign up to Miro free and copy the template.

Step 2. List potential failure modes

What failures have happened over recent years? What are the ways in which the failures occurred? Use sticky notes to write down all the potential failure modes and move them to the area called ‘Detect a failure mode’ on the board.

an fmea is primarily considered a problem solving tool

Step 3. Speculate possible outcomes

What is the outcome if a certain system fails? How might each of the process components fail? Record system-wide effects for each failure mode on stickies and put them in the same frame.

an fmea is primarily considered a problem solving tool

Step 4. Assign S, O, and D rankings

Move your stickies with failure modes to the frame #2 and assign severity numbers. You can create tags and add them to stickies to classify failure modes based on their severity numbers.

In frames #2 and #3 of the template, assign the probability of occurrence and likelihood of detection using tags.

Step 5. Combine S, O, and D to get the Risk Priority Number

Multiply S x O x D. Once combined, they will give you the RPN. Copy failure modes into frame #5 and add RPN to each sticky.

an fmea is primarily considered a problem solving tool

Step 6. Designate which system requires immediate maintenance

Which system has the highest RPN? Remember, higher RPN = more critical, lower RPN = less critical.

Step 7. List recommended actions

Brainstorm scenarios for improving various products or processes. In our example, the most critical failure mode is ‘Cash not disbursed’, so we would list action items for the team to address it.

Step 8. Share your schedule and FMEA

After your FMEA template is filled in, you can share it with all the major stakeholders even if they didn’t participate in the mapping process.

  • Miro makes FMEA easy

FMEA is a powerful tool that can help your team improve safety, quality, customer satisfaction, and profits. FMEA may seem complicated, but don’t worry! Miro’s template makes the procedure simple.

Pre-made, flexible FMEA templates

Use frames, colorful sticky notes, tags and other features to express and organize your thoughts and issues. These templates enable you to prioritize product or process deficiencies to ensure the best results and satisfy customers. You can also add other templates (such as risk assessment matrix , timeline , or action plan ) to visualize the big picture and make the most effective decisions.

Easy document upload

Add visual content including charts, schemes, and pictures to enhance your conceptual presentation. Upload documents and files that can integrate with a wide range of choices such as Google G Suite, Dropbox and JIRA. When you visualize the different components of your product or process, you can better evaluate it with FMEA.

Collaborative tools for members of all different teams

When your team collaborates on a visual whiteboard , you can work together to find and discuss issues. Add comments, refer to each other, and ask questions in video chat to save time and increase productivity. Working collaboratively allows your team to share in contributing to the FMEA process—which means greater improvements, higher quality, and better results!

Improving Product Quality and Efficiency with FMEA

Updated: April 9, 2023 by Lori Kinney

an fmea is primarily considered a problem solving tool

Overview: What is FMEA?

When it comes to risk assessment in Lean Six Sigma, one of the most useful tools you can use is FMEA. FMEA stands for Failure Modes and Effects Analysis. It’s a tool used to identify and prioritize potential failures of a product or process through a systematic approach that involves identifying risks, evaluating consequences and determining actions needed.

All risks are evaluated in terms of severity (how severe the consequences of the failure are), occurrence (how likely it is for the failure to occur), and detection (the chance of detecting the failure before it happens).  Each are given their own score on a scale of 1 to 10, and those numbers are then multipled by each other to determine the risk priority number (RPN).

The ultimate goal of an FMEA is to reduce the risk of failures occurring in the future.

3 Benefits of FMEA

The FMEA tool provides a structured approach for identifying and mitigating risks. It helps ensure that you’re analyzing all aspects of your process, from design to implementation, to identify potential problem areas.

The three main benefits are:

1. Identify and prioritize risks.

FMEA helps identify the major risks to a project or process. By identifying these, you can then prioritize them, so that you focus on reducing the biggest risks first.

2. Improve product quality.

FMEAs help improve product quality by ensuring that all possible failure modes are considered before they occur. This allows you to improve your processes so that they’re less likely to fail in the future, leading to higher profits as well as happier customers because their needs are being met more effectively than ever before!

3. Improve process efficiency.

FMEAs also improve process efficiency —if you’re using preventative measures like having adequate equipment on hand at all times (instead of waiting until after something breaks down), then there’s less downtime which means better productivity overall! This is especially true when combined with other tools like Six Sigma or Lean Six Sigma training courses such as “Risk Assessment” – they allow us to see how each step contributes towards increasing profitability through cost reduction efforts while simultaneously improving customer satisfaction levels through better service delivery practices.

Why is FMEA Important to Understand?

Understanding the FMEA tool is important for several reasons. First, it makes it possible to identify all of the failure modes and their consequences in a process. This is one of the most important steps in risk management as it allows you to plan how to address those issues. Second, it can be used as part of continuous improvement efforts because it helps identify opportunities for improvement. Finally, if you’re interested in understanding customer needs more completely, then FMEA will help you do so by making sure that all aspects of a product or service are considered when creating your offering.

An Industry Example of FMEA

An example of the use of FMEA in industry is the automotive industry. The purpose of FMEA is to identify and mitigate risks in the manufacturing process. An automotive manufacturer has developed a new vehicle that requires a large initial investment from the company, which in turn requires them to find new suppliers for components used in their assembly line. If a supplier cannot provide parts at an affordable price, it could be catastrophic for the company’s bottom line and future success.

A good way to mitigate this risk would be to perform an FMEA on each potential supplier beforehand so that if one falls through, you can move on to another option quickly without missing deadlines or incurring unnecessary losses from inventory storage costs or other expenses associated with finding replacement suppliers.

3 Best Practices When Thinking About FMEA

FMEAs are an essential tool for any organization that aims to implement a Lean Six Sigma program. Best practices for implementation should include:

1. Assess the current process to determine its level of maturity.

This can be done by using the DMAIC model, which stands for Define, Measure, Analyze, Improve and Control.

2. Start performing regular audits and measurements to see where your processes stand in terms of quality.

You’ll also want to make sure that you’re continually improving them by implementing small changes as needed.

3. It’s important not only to assess your system as a whole but also each individual part within it.

This will help you determine what changes need to be made and how they should be implemented across all areas involved in production or service delivery.

Frequently Asked Questions (FAQs) About FMEA

Are there different types of fmeas.

Yes. There are a number of different types of FMEAs, but the two most popular are PFMEA (where “p” stands for process) and DFMEAs (where “d” stands for design).

What is the purpose of a FMEA?

The purpose of an FMEA is to help organizations find problems with their products before they hit the market by identifying areas where there could be failure modes, determining how likely those failure modes might be, and coming up with ways to overcome those failures through mitigation plans and/or preventive action items (PAIs). An effective way for companies to avoid costly rework later down the road would be by using tools like FMEDAs at each stage during product development—ideally before any prototypes are built! By doing so they will save time while also reducing waste because fewer changes need made after initial development stages have already been done over again due being implemented incorrectly initially anyway.

In which phase of Six Sigma is FMEA used?

The FMEA tool is used in both the analyze and improve phases of the DMAIC framework. It could be one or the other, or both, depending on the purpose of your project.

Critical to Project Planning

FMEA is an important tool for understanding and managing risk. When it comes to lean business, you should always remember that the goal is to improve quality while reducing costs and time. By using FMEA as part of your project planning process, you can minimize the risk of errors that could lead to costly rework or even product recalls.

An Introduction to Failure Modes and Effects Analysis (FMEA)

One question I frequently get asked is "How do I know if I should do a failure modes and effects analysis (FMEA) or a root cause analysis (RCA)?" The answer is simple: are you trying to find out what DID happen or what COULD happen? Typically, root cause analysis is used to diagnose an event that has already occurred. The term is often synonymous with an accident investigation or failure analysis. RCA takes place after the incident to determine what went wrong. It is considered reactive. FMEA, on the other hand, is proactive and conducted before the problem happens. An FMEA is a systematic approach to anticipate and evaluate events that could happen. Its primary objective is to identify potential failure modes (i.e., the way that something can fail) and their impacts so that preventive measures can be implemented to minimize the overall risk associated with a process, product, or service.

FMEA Origin and Evolution

FMEA was developed by the U.S. military in the 1940s. Today, it serves as a critical tool in safety and reliability engineering across virtually every industry – from determining the airworthiness of planes, to achieving clinically desirable outcomes in healthcare. In process applications, such as chemical and refining plants, the fundamentals of FMEA are part of Process Hazard Analysis (PHA). Reliability-centered Maintenance (RCM), which defines risk-based operations and maintenance activities is also based on FMEA. There is sometimes a misconception that FMEA only applies to engineered systems, such as equipment, mechanisms, or assemblies. However, the basis for an FMEA is simple cause-and-effect. Thus, it can be applied to any system or process where it’s important to understand what events could prevent the desired outcome from being realized.

The FMEA Table

The FMEA table provides a structure for ranking the failure modes in a system. In the first column of the table, subsystems and components are listed on their own row. This initial list can be basic with 5-10 items. Depending on the complexity, more detail may need to be added to accurately reflect the system. People in your organization familiar with the system will be able to explain specific aspects of its operation and what level of detail is needed. The second column lists the different ways in which each item can lose function. Each of these failure modes gets its own row. A single item in the first column may have a few different failure modes. The potential effects (the negative outcomes) are listed in the third column. There are additional columns for capturing the causes of the failure modes and what is currently in place to prevent and control each failure mode. This is an example FMEA worksheet in Microsoft Excel that we give out during our FMEA 101 online short course.  

FMEA Table

Ranking the Failure Modes

The risk priority number (RPN) ranks the failure modes. Each failure mode is assigned three numbers on a scale of 1-10. It’s also acceptable to begin with a simpler ranking of “low-medium-high” using numbers from 1-3 or even 1-5.

The first number represents the severity of the effect if that failure mode were to occur. The second number is the likelihood of that failure mode occurring. For both severity and likelihood, 1 is the lowest severity, 10 is the highest. The third number is the ability to detect that failure mode if it does occur. The detection number is higher if the failure mode is difficult to recognize since it would make the risk higher. The number is lower if it is easy to detect.  Ideally, an organization would have operating or experiment data for these rankings. If not, people can make a relative estimate of the number, but it’s more subjective. Involving people with firsthand experience of the system is critical to ensure that every bit of relevant information is captured and documented. In the case of a process plant, for example, this could mean the operators, maintenance technicians, engineers, original equipment manufacturers (OEMs) and even their suppliers. Once all three numbers are written down, they’re multiplied together to get the RPN which is a number between 1-1,000 (10 x 10 x 10 is the worst-case scenario). This one number is the relative risk for each of the failure modes in the table. The table is re-sorted with the highest risk failure modes at the top and the lowest at the bottom. This sorted FMEA table defines your organization’s priorities for mitigating risk in this system.

Example ratings-1

Risk Reduction Plan

All failure modes don’t need to be addressed right away since some will be lower risk. The initial plan may be to mitigate only some of the higher risks at the top. An organization may draw a horizontal line on the table where only failure modes above that threshold level will be addressed. A specific action plan is defined to lower the risk of each failure mode. This is done by either reducing the severity of the consequences, lowering the likelihood of it occurring, or changing the ability to detect it. The action plan can pull from industry standards and best practices, as well as creative ideas from those within the organization. These types of solutions are around us every day. Airbags, for example, don’t prevent car accidents, but they can significantly reduce the severity of injuries. A second look at your grocery list before the register can significantly reduce the likelihood of forgetting something at the store. That simple double-check is a normal part of every commercial flight you’ve been on. And a smoke detector doesn’t prevent a house fire from starting, but it provides an early warning to those inside even if they’re asleep.

Update the Table…and Keep It

After solutions are put in place their effectiveness needs to be measured. In other words, did the specific actions reduce the risk of that failure mode occurring? If the numbers for severity, likelihood and detection are lower, then the answer is “yes." The table can be updated to get the RPN for the failure modes that were addressed. If the RPN was lowered sufficiently, then the objectives for that initiative may have been met. Some organizations may select a new lower RPN threshold and begin the cycle again. The level of effort for this type of exercise is ultimately based on what your organization considers an acceptable level of risk (i.e., reliability). Airlines with 4,000 flights a day or a children’s hospital that delivers 4,000 doses of medication daily will have a different risk tolerance and operating mode than other organizations. Acceptable levels of risk vary across industry and organization as do the approaches to problem solving and prevention. If a system is to be a planned part of the operations for years, then the FMEA can be updated over the life of the system. People may come and go, but specific failure modes can remain the same. Effective solutions should stay in place too. Sometimes a turnover in personnel produces unwanted changes in operations. Maintaining this information provides continuity to the organization.

Layout the FMEA Visually in Microsoft Excel

A table is the best way to organize failure modes, effects, and causes to calculate the RPN. It makes it easy to list the systems and subsystems, identify failure modes along with their effects and causes. It’s also simple to calculate and periodically update the risk priority number.

A program like Microsoft Excel works well for documenting the entire FMEA in a spreadsheet. Each worksheet is already organized as a table and sorting by the RPN number is already a function within Excel under data > sorting.

Traditional FMEA defines failure mode, effect, and cause as distinctly different terms, which provides a clear framework for each of the failure modes. Because FMEA is based on cause-and-effect, every relationship in the table can be connected visually into one larger diagram. Clients who use our Cause Mapping ® method for root cause analysis create Cumulative Cause Map™ diagrams to capture the different failure modes they’ve identified over the operational life of those systems and equipment. The diagram complements the FMEA table to show how all the parts fit together.  Check out our How are FMEA and RCA connected? blog post to download and walk through an example of a Cumulative Cause Map™ using printer failures

All the information can be organized in one Excel file. Below is an example FMEA for a conveyor system. There is a separate worksheet for the overall diagram of the conveyor system (Fig 1.), the FMEA table for the conveyor system (Fig 2.), and the Cumulative Cause Map™ diagram for the conveyor showing all the cause-and-effect relationships together (Fig. 3.).

Failure Modes and Effects Analysis (FMEA) Tool

A systematic, proactive method for evaluating a process or product to identify where and how it might fail and to assess the relative impact of different failures, in order to identify the parts of the process that are most in need of change.

  • FMEA tool instructions, example, and template

Note: Spanish and Portuguese translations of this tool also available for download.

Failure Modes and Effects Analysis (FMEA) includes review of the following:

  • Steps in the process
  • Failure modes (What could go wrong?)
  • Failure causes (Why would the failure happen?)
  • Failure effects (What would be the consequences of each failure?)

Teams use FMEA to evaluate processes for possible failures and to prevent them by correcting the processes proactively rather than reacting to adverse events after failures have occurred. This emphasis on prevention may reduce risk of harm to both patients and staff. FMEA is particularly useful in evaluating a new process prior to implementation and in assessing the impact of a proposed change to an existing process.

*NOTE: Before filling out the templates, first save the PDF files to your computer. Then open and use that version of the tool. Otherwise, your changes will not be saved.

Process Failure Modes and Effect Analysis (PFMEA) stands as a cornerstone in the realm of proactive risk management in business processes. This analytical method is designed to forecast and preemptively address process failures, establishing a culture of foresight rather than reactive problem-solving. In scenarios like a car production plant gearing up for a transition between manufacturing different car types, the complexity and multitude of variables involved make PFMEA not just useful, but essential.

The methodology allows teams to systematically unravel and prioritize potential challenges, setting the stage for smooth transitions and efficient operations. As we delve deeper into the nuances of PFMEA, we uncover its critical role in enhancing safety, increasing efficiency, and saving valuable time across various project stages.

What is process failure mode and effects analysis.

PFMEA is an analytical method used in business to predict and prevent process failures before they occur. Conducting a PFMEA about a process to understand what could go wrong is a proactive approach to risk assessment rather than being reactive to issues after they happen.

By using this approach teams can identify and resolve problems before they occur for example is a car production plant is looking to switch over car manufacturing from one car type to another there are a lot of moving parts in that process. Before they start the changeover, they could conduct a PFMEA to identify all the potential problems and prioritize them based on risk before the changeover activity happens.

In situations like this PFMEA and FMEA in general are critical tools that can reduce risk, improve safety, increase efficiency, and save time in projects. This comprehensive evaluation allows organizations to make informed decisions about where to focus their improvement efforts for the greatest impact.

When to Use Process Failure Mode and Effects Analysis

PFMEA is a systematic approach used to identify and address potential failure points in a process. Determining the appropriate time to use PFMEA is important for maximizing its effectiveness. Here are several scenarios and stages in a process’s lifecycle when PFMEA is particularly beneficial:

During Process Design or Development

When designing a new process or system , PFMEA helps identify potential failure modes early. This proactive approach ensures that the process is robust and reliable from the start.

If an existing process is being significantly modified or updated, PFMEA is used to assess the impacts of these changes and identify new risks that might emerge.

Prior to Process Implementation

Implementing PFMEA before a process goes into full-scale production can identify potential issues that could lead to defects, downtime, or inefficiencies.

Conducting PFMEA during pilot runs or trial phases of a process can provide insights into potential failure modes and allow for adjustments before broader implementation.

When Quality Issues or Inefficiencies are Identified

If a process is experiencing quality problems or higher than acceptable defect rates, PFMEA can be used to systematically identify the root causes and implement corrective actions.

When inefficiencies or bottlenecks are detected in a process, PFMEA can help in pinpointing failure modes contributing to these issues.

As Part of Risk Management and Compliance

In industries where adherence to certain standards is required (e.g., automotive, aerospace, pharmaceuticals), PFMEA is often a necessary part of compliance.

For any process where risk mitigation is a priority, PFMEA is an essential tool.

Step-by-Step Guide to Performing A PFMEA (With Examples)

Step 1: assemble a cross-functional team.

The complexity of most processes, products, or systems often means that no single person has a complete understanding of all aspects. Therefore, a cross-functional team brings together different perspectives and expertise, leading to a more complete analysis.

  • Identify key stakeholders and experts from various relevant departments.
  • Include representatives from design, engineering, quality assurance, operations, and any other relevant department.
  • Choose a team leader, preferably someone experienced with PFMEA, to guide the process and ensure it stays on track.
  • Ensure that team members are trained on the basics of PFMEA so everyone starts with a foundational understanding.

Step 2: Define the Scope

To ensure that the PFMEA remains focused and manageable, it’s crucial to clearly define what will be analyzed. This prevents the process from becoming too broad or overlooking critical areas.

  • Determine if the PFMEA will focus on a product, a process, or an entire system.
  • Define boundaries by clarifying what is included and what isn’t. For instance, if analyzing a manufacturing process, decide which specific stages or components will be the subject of the FMEA.
  • Document any known assumptions or constraints that could influence the analysis.

Step 3: List Potential Failure Modes

At this stage, the goal is to identify all the potential ways the subject (be it a process, product, or system) might fail. This is the foundation of the PFMEA, as understanding these failure modes is key to addressing them.

  • Conduct brainstorming sessions with the cross-functional team to list potential failures. Encourage open communication and ensure every idea is considered without immediate judgment.
  • Review past data, including incident reports, customer feedback, or warranty claims, to identify historical failure modes.
  • For products or systems, consider using techniques like fault tree analysis or component testing to identify potential failure modes.
  • Document each failure mode with a clear description. For instance, instead of just noting “motor failure,” specify “motor overheating leading to failure.”

Step 4: Evaluate the Potential Failure Effects, Potential Causes, and Current Controls

This step aims to further break down each identified failure mode by understanding its impact, root causes, and existing preventive measures.

  • Potential Failure Effects : Determine what the consequences of each failure mode are. This can range from minor inconveniences to safety hazards.
  • Potential Causes : Identify the root causes leading to the failure mode. This is essential for preventive action.
  • Current Controls : Determine existing processes or measures that are in place to either detect or prevent the failure mode from occurring.

Step 5: Evaluate Severity, Occurrence, and Detection

The aim here is to quantify the risk associated with each failure mode. These three criteria help in understanding the magnitude of the problem and in prioritizing corrective actions.

  • Severity (S) : Rate the seriousness of the consequences if the failure occurs. Typically rated on a scale of 1 (least severe) to 10 (most severe).
  • Occurrence (O) : Assess the likelihood of the failure mode occurring. Again, this is usually on a scale of 1 (least likely) to 10 (most likely).
  • Detection (D) : Evaluate the likelihood that the current controls will detect the failure mode before it reaches the end customer. This is rated on a scale where 1 means it’s very likely to be detected and 10 means it’s very unlikely.
  • Note: You can find the full classification of scoring within our FMEA Template .

Step 6: Calculate RPN and Prioritize

The Risk Priority Number (RPN) provides a numerical value that represents the overall risk of each failure mode. It helps in prioritizing which failure modes should be addressed first.

Calculate RPN : For each failure mode, multiply the Severity, Occurrence, and Detection ratings:

Prioritize : Once RPN values are calculated for all failure modes, sort them in descending order. Those with the highest RPNs should be given priority for corrective action since they represent the highest risk.

Step 7: Develop Action Plans

The aim of this step is to design and plan corrective actions for the identified failure modes, particularly those with the highest RPN values. Addressing these failure modes will have the most significant impact on improving the process or product.

  • Prioritize Failure Modes : Start by focusing on the failure modes with the highest RPNs. These represent the highest risks and should be addressed first.
  • Brainstorm Solutions : Convene the cross-functional team to brainstorm potential solutions to the identified failure modes. Consider redesigning the process, adding inspections, or implementing new technologies.
  • Assign Responsibility : For each action item, assign a responsible person or team. This ensures accountability and clarity on who will drive the corrective action.
  • Set Deadlines : Establish a timeline for implementing the corrective actions. This helps in tracking progress and ensuring timely completion.
  • Document Everything : Maintain a detailed record of the planned actions, responsibilities, and timelines. This documentation is vital for tracking progress and future audits.

Step 8: Implement and Monitor

After developing action plans, this step ensures that the corrective measures are put into practice and that their effectiveness is monitored over time.

  • Execute the Action Plans : Implement the corrective actions as planned. This might involve training staff, purchasing new equipment, redesigning processes, or any other required change.
  • Monitor Continuously : Regularly check the effectiveness of the implemented actions. Use metrics, inspections, or tests to evaluate whether the corrective actions are reducing or eliminating the failure modes.
  • Feedback Loop : Create a feedback mechanism where frontline staff can report on the effectiveness of the corrective actions. Their insights are invaluable as they work directly with the process or product.
  • Adjust as Necessary : If a corrective action isn’t yielding the desired results, don’t hesitate to modify it or try a different approach.
  • Update FMEA : As corrective actions are implemented and processes change, the FMEA should be updated to reflect the current state. This might lead to changes in RPN values and further refinements.
  • Celebrate Successes : Recognize and celebrate when corrective actions lead to significant improvements. This fosters a positive culture of continuous improvement.

How does a PFMEA differ from DFMEA?

The difference between a PFMEA and a Design Failure Mode and Effects Analysis ( DFMEA ) is primarily based on their areas of focus and application within the lifecycle of a product or service. Both are systematic methodologies used for identifying, analyzing, and mitigating risks, but they apply to different aspects of production and development.

Process Failure Mode and Effects Analysis (PFMEA)

PFMEA is focused on processes used in the manufacturing or execution of a service. It examines each step in a process to identify where and how failures might occur.

The primary goal is to ensure operational efficiency and process reliability. PFMEA aims to identify potential failures that can impact the quality of the output, including production delays, inefficiencies, and defects.

PFMEA is used in analyzing manufacturing processes, assembly lines, service delivery processes, and other operational procedures.

PFMEA looks at factors such as human error, equipment failure, material quality, environmental conditions, and process variability. It assesses the potential impact of these factors on the process and the final product or service.

The outcome of PFMEA is often process improvement, through changes in procedures, quality control enhancements, training, or equipment upgrades.

Design Failure Mode and Effects Analysis (DFMEA)

DFMEA is concerned with the design of a product. It systematically evaluates a product’s design to identify potential failures and their causes.

The main objective is to enhance product safety, reliability, and functionality. DFMEA seeks to uncover design weaknesses that could lead to failure in the product’s use or reduce its lifespan.

DFMEA is applied during the product design phase, often in industries like automotive, aerospace, electronics, and consumer goods manufacturing.

The analysis in DFMEA includes assessing the failure modes related to materials, components, subsystems, interfaces, and overall product design. Factors like material properties, design tolerances, mechanical stress, and environmental impacts are considered.

The outcomes include design modifications, material changes, and the establishment of design standards and specifications to mitigate identified risks.

Key Differences

PFMEA is process-oriented (focusing on how a product is made or a service is provided), whereas DFMEA is design-oriented (focusing on what is being made).

PFMEA deals with the risks associated with process variables, whereas DFMEA deals with risks inherent in the design of the product itself.

PFMEA is typically performed during process development and before the full-scale production or implementation of a service, while DFMEA is conducted during the product design phase, often before a prototype is even created.

PFMEA aims at ensuring efficient and reliable processes, reducing operational failures and defects. DFMEA targets the elimination or reduction of design-related failures, improving product safety, reliability, and functionality.

The strategic application of Process Failure Modes and Effects Analysis (PFMEA) transcends mere problem-solving; it is an integral part of process optimization and risk management. From its crucial role in the design and development phases of a process to its application in existing process modification and quality control, PFMEA serves as a comprehensive tool for organizational growth and efficiency.

Its ability to adapt to different scenarios, be they in the design or operational stages, underscores its versatility. Moreover, the structured approach of PFMEA, involving cross-functional teams and systematic evaluation, ensures that every potential risk is thoroughly assessed and effectively managed. In sum, PFMEA is not just a methodological approach to risk assessment but a pathway to operational excellence and strategic foresight in business processes.

Q: What is the Risk Priority Number (RPN) and how is it calculated?

A : The Risk Priority Number (RPN) is a numerical representation of the overall risk associated with a specific failure mode. It is calculated using the formula:

Here, Severity, Occurrence, and Detection are individual ratings usually on a scale of 1 to 10, representing the impact, frequency, and detectability of a failure mode, respectively.

Q: How often should a PFMEA be updated?

A : A PFMEA is a living document and should be updated regularly. Specifically, it needs to be revisited whenever there are significant changes in the process, introduction of new technologies, or after a certain period as defined by your company’s quality guidelines. Failure to update can render the PFMEA ineffective.

Q: Can PFMEA be used for services, or is it limited to manufacturing?

A : While PFMEA is commonly associated with manufacturing, its principles can be applied to services and other non-manufacturing processes as well. The goal remains the same: to identify and mitigate risks associated with failure modes in any process.

Q: What is the role of a cross-functional team in PFMEA?

A : A cross-functional team brings together expertise from different departments like engineering, quality control, and operations. This diversity allows for a more comprehensive analysis of potential failure modes and more robust solutions, ensuring that all perspectives are considered.

Q: How can historical data be used in conducting a PFMEA?

A : Historical data, such as past incident reports, customer feedback, and quality audits, can provide valuable insights into potential failure modes, their effects, and occurrences. This data can inform the Severity, Occurrence, and Detection ratings, making your PFMEA more accurate and reliable.

What is a FMEA 

Expanded as Failure Mode Effect Analysis

It is a risk management tool - starts with a review of the process for failure modes (what could go wrong), then their effects, then causes of the failure modes. It also takes in to account the current controls in place to prevent failure.

The severity of failure effect; occurrence frequency of causes and ability to detect (of the current controls) are all rated and multiplied to produce an RPN -risk priority number; which once sorted in descending order can tell the high priority risk areas. 

How to do FMEA

Gather the doers, explain the process

If you haven't done FMEA before, you may want to get experts to help

FMEA won't get done in a single sitting - so its ideal to gather the team for each step (or some steps together)

Between steps, you and /or a team member can work on the file to clean / update based on the last meeting and procure data as required

This is best done in an excel file

Step 1: PROCESS STEPS - write the major process steps or these could be changes you are planning to do 

Step 2: FAILURE MODES - Against each Process step, list ways in which it can go wrong.

There would be multiple ways, so keep adding rows

You don't need to weed out now

Do spend time on each process step, ask questions - "what else", "how has it failed in the past".....

Step 3: FAILURE EFFECTS- List the various ways in which the failure modes would impact the customer

Step 4: CAUSES - List the causes of why the failure may happen

Step 5: CURRENT CONTROLS - List the current controls available to prevent/detect the failure

Now we do the ratings. Please check if your organization has a rating scale table for FMEA, which you can use for rating. 

This will ensure that your stakeholders can relate to ratings

If your organization doesn't have one, see if you can google one for your use and before that confirm with an expert if possible

Step 6: PRODUCE RPN

Severity Rating - How severe is the impact of Effects; Low-1 to High-10

Occurrence Rating - How frequently do the Causes occur; Low-1 to High-10

Detection Rating - How effective is the Control in detecting/ preventing the failure; Low-10 to High-1

Calculate RPN = Severity * Occurrence * Detection ratings

RPN would range from 1 (1*1*1) to 1000 (10*10*10)

Sort in Descending order as per RPN

Check for consensus, make changes if necessary​

You now have current state FMEA

When to use FMEA

To identify ways and methods in which a product or process or solution can fail

FMEA may be used to choose areas where projects need to done

At the start of a project to determine risk areas

At the start of the implementation of an improvement project

FMEA as an exercise can be used to reduce failure modes in a process

Improving from current state - RPN 

Post sorting the current state FMEA - RPN in descending order you now know your biggest risk areas

Check with your organisation for a risk threshold RPN

Lets take that as 100, so any mode above RPN 100, needs to be controlled

STEP 7 : For each mode above threshold, review 

The causes - can you get to the root cause ? ; can you reduce the frequency of occurrence, if not eliminate

The controls - can you increase the effectiveness of controls eg if the current control for people jumping off a 1 mile long bridge was , a police man patrolling - you can put very high barricades, that have spikes to dissuade people from climbing and jumping off.

Do note that we wont be able to impact severity - if someone jumps - it may be fatal, so severity remains 10 , however occurrence can be reduced by improving controls

Once ​you have reviewed and determined actions, now implement them with tracking and update the RPNs .

This review can throw up many projects to reduce RPNs.
