FMEA prioritizes failures according to severity, frequency and detectability. Severity describes the seriousness of failure consequences. Frequency describes how often failures can occur. Detectability refers to degree of difficulty in detecting failures.
What is FMEA in simple words?
Failure Modes and Effects Analysis (FMEA) is a systematic, proactive method for evaluating a process 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.

Why it is called 6 Sigma?
It's called Six Sigma because the term sigma refers to one standard deviation in a data set. The idea is that six such deviations should occur before the process results in a defect. When a process achieves Six Sigma, it reaches a point where only 3.4 errors per one million process events result in a defect.

Why is FMEA used?
The purpose of the FMEA is to take actions to eliminate or reduce failures, starting with the highest-priority ones. Failure modes and effects analysis also documents current knowledge and actions about the risks of failures, for use in continuous improvement. FMEA is used during design to prevent failures.
How does FMEA work?
An FMEA is an engineering analysis done by a cross-functional team of subject matter experts that thoroughly analyzes product designs or manufacturing processes early in the product development process, finds and corrects weaknesses before the product gets into the hands of the customer.

FMEA is sometimes known as DFMEA (which stands for Design Failure Mode and Effect Analysis) or PFMEA (which means Processes Failure Mode and Effect Analysis). These are used to analyse potential failures in product design or in the processes of a business unit, respectively.
What is a FMEA in Lean Six Sigma?
Six Sigma DMAIC Process - Improve Phase - Failure Mode Effect Analysis (FMEA) FMEA identifies all the probable failure modes for the product or process. It prioritizes the failure modes for focused attention by using a scoring model based on Severity (S), Occurrence (O) and Detect ability (D).
What is FMEA?
Failure Mode and Effects Analysis (FMEA) is a proactive method of uncovering potential failures in business processes in order to prevent them from happening or mitigate their effect by finding out where they might occur and determining their impact.

Why is FMEA important?
Performing FMEA is important because it helps determine which parts of a process need to be prioritized for changes that aim to eliminate or reduce the probability of failures.
How to prioritize FMEA?
From the list of issues or failure modes, determine which problems to prioritize by calculating the FMEA Risk Priority Number (RPN). Designate a rating of 1-10 for the Severity, Occurrence, and Detection and multiply these three with each other. Do this risk analysis for all of the items on the list. Seeing the issues with the highest RPN should help you decide which problem/s to prioritize.

What is FMEA in a spreadsheet?
FMEA is a qualitative and systematic tool, usually created within a spreadsheet, to help practitioners anticipate what might go wrong with a productor process. In addition to identifying how a product or process might fail and the effects of that failure, FMEA also helps find the possible causes of failures and the likelihood of failures being detected before occurrence.
How to assess a FMEA?
An FMEA uses three criteria to assess a problem: 1) the severity of the effect on the customer, 2) how frequently the problem is likely to occur and 3) how easily the problem can be detected. Participants must set and agree on a ranking between 1 and 10 (1 = low, 10 = high) for the severity, occurrence and detection level for each of the failure modes. Although FMEA is a qualitative process, it is important to use data(if available) to qualify the decisions the team makes regarding these ratings. A further explanation of the ratings is shown in Table 2.
What is the first step in completing an FMEA?
One of the first steps to take when completing an FMEA is to determine the participants. The right people with the right experience, such as process owners and designers, should be involved in order to catch potential failure modes. Practitioners also should consider inviting customers and suppliers to gather alternative viewpoints.
What is process FMEA?
PFMEA is a methodical approach used for identifying risks on process changes. The Process FMEA initially identifies process functions, failure modes their effects on the process. If there are design inputs, or special characteristics, the effect on end user is also included. The severity ranking or danger of the effect is determined for each effect of failure. Then, causes and their mechanisms of the failure mode are identified. The assumption that the design is adequate keeps the focus on the process. A high probability of a cause drives actions to prevent or reduce the impact of the cause on the failure mode. The detection ranking determines the ability of specific tests to confirm the failure mode / causes are eliminated. The PFMEA also tracks improvements through Risk Priority Number (RPN) reductions. By comparing the before and after RPN, a history of improvement and risk mitigation can be chronicled.

How many sections are there in a process FMEA?
There are five primary sections of the Process FMEA. Each section has a distinct purpose and a different focus. The PFMEA is completed in sections at different times within the project timeline, not all at once. The Process FMEA form is completed in the following sequence:
When is PFMEA applied?
The PFMEA is applied when: There is a new technology or new process introduced. There is a current process with modifications, which may include changes due to updated processes, continuous Improvement, Kaizen or Cost of Quality (COQ).
What is failure mode?
Failure Modes are the anti-functions or requirements not being met. There are 5 types of Failure Modes:
Where is the highest severity in PFMEA?
The highest severity is chosen from the many potential effects and placed in the Severity Column. Actions may be identified to can change the design direction on any failure mode with an effect of failure ranked 9 or 10. If a recommended action is identified, it is placed in the Recommended Actions column of the PFMEA.
Can there be more than one failure mode?
All effects should appear in the same cell next to the corresponding failure mode. It is also important to note that there may be more than one customer; both internal and external customers may be affected.
