Failure Mode & Effects Analysis (FMEA) is a step-by-step approach for identifying all possible failures in a design, a manufacturing or assembly process, or a product or service. The purpose of the FMEA is to take actions to eliminate or reduce failures, starting with the highest-priority ones. FMEA also documents current knowledge and actions about the risks of failures, for use in continuous improvement. (Note: For users from the automotive industry, kindly note that the FMEA process described in this presentation is not aligned to the AIAG-VDA FMEA methodology.)
In this training presentation, you can teach your employees on the proper steps to construct an FMEA for a design or process, and then implement action plans to eliminate or reduce the risks of potential failures.
NOTE: This presentation includes an FMEA Form (in Excel format) as a supplemental document.

Primary Topics Covered
• FMEA Overview - FMEA is a structured method for identifying potential failure modes in products and processes, estimating associated risks, and prioritizing actions to mitigate those risks.
• FMEA Types - Two primary types of FMEA are discussed: Design FMEA (DFMEA) focuses on product design, while Process FMEA (PFMEA) addresses operational processes.
• Risk Priority Number (RPN) - RPN is calculated by multiplying Severity, Occurrence, and Detection scores, providing a quantifiable measure to prioritize risks.
• FMEA Procedure - The step-by-step process for conducting an FMEA includes forming a team, identifying failure modes, assessing effects, and developing action plans.
• Scoring System - A detailed scoring system is provided for Severity, Occurrence, and Detection, allowing teams to evaluate risks systematically.
• Common Pitfalls - The presentation highlights frequent mistakes in FMEA execution, such as inadequate team involvement and failure to re-evaluate after implementing actions.

Topic FAQ
Document FAQ
These are questions addressed within this presentation.
What is FMEA?
FMEA stands for Failure Mode & Effects Analysis, a structured approach to identifying potential failure modes in products and processes and prioritizing actions to mitigate risks.
When should FMEA be used?
FMEA should be utilized early in the design phase of new products or processes, during changes to existing systems, or when assessing carry-over designs in new applications.
What is the Risk Priority Number (RPN)?
RPN is a calculated score that helps prioritize risks by multiplying the Severity, Occurrence, and Detection ratings associated with each identified failure mode.
What are common pitfalls in conducting FMEA?
Common pitfalls include inadequate team involvement, rushing through the identification of failure modes, and failing to re-evaluate RPNs after implementing corrective actions.
How can FMEA improve operational efficiency?
By systematically identifying and addressing potential failures, FMEA helps organizations enhance product reliability, reduce costs associated with failures, and improve overall customer satisfaction.
What types of FMEA are there?
The 2 primary types are Design FMEA (DFMEA), which focuses on product design, and Process FMEA (PFMEA), which addresses operational processes.
How do you calculate RPN?
RPN is calculated by multiplying the scores for Severity, Occurrence, and Detection: RPN = Severity x Occurrence x Detection.
What is the scoring system used in FMEA?
The scoring system typically uses a scale of 1-10 or 1-5 for Severity, Occurrence, and Detection, allowing teams to assess risks quantitatively.
