FMEA
WHAT IS A FMEA?
The Failure Mode and Effect Analysis (FMEA) is a Prevention Technique used to define, identify and eliminate potential problems from a system, subsystem, component or a process. Focus on Prevention An assessment of Risk Safety Regulatory Customer Satisfaction Program Coordinated/Documented team effort A method to determine the need and priority of actions

FMEA
Criticisms of FMEA
FMEA often misses key failures FMEA performed too late does not affect key product/process decisions The FMEA Process is tedious The Risk Priority Number is not a good measure of Risk

OVERVIEW OF THE FMEA PROCESS Define the scope of the study. Scope Definition Worksheet Select the FMEA team. Team Start-Up. Team Start-Up Worksheet. Review Design Intent / Process Function and the process (PFMEA) or product (DFMEA) to be studied. MRD Process: Flowchart or Traveler Product: Blueprint or Schematic

FMEA
Identify all current design/process controls to prevent/detect the failure mode. Rate the relative risk of all controls. Detection/Prevention Prioritize for action. Calculate the RPN (risk priority number). Use the Pareto Principle. Take action. Calculate the resulting RPN.

FMEA
Timing
One of the most important factors for the successful implementation of an FMEA program is timeliness. It is meant to be a before-the-event action, not an after-the-fact exercise. Actions resulting from an FMEA can reduce or eliminate the chance of implementing a change that would create an even larger concern.

FMEA
Part 1: Who is the customer? Part 2: What are the product features and characteristics? Part 3: What are the product benefits? Part 4: Study the entire product or only components or subassemblies? Part 5: Include consideration of raw material failures? Part 6: Include packaging, storage, & transit? Part 7: What are the manufacturing process requirements & constraints.

FMEA
Process FMEA
It is initiated by a member from the Operations or Engineering. Representatives from Design, Assembly, Manufacturing, Materials, Quality, Service and the Area Responsible for the next assembly should be involved. The Process FMEA assumes the product/process as designed will meet the design intent.

Potential Failures
(D) Manner in which a component, subsystem or system could fail to meet design intent (P) Manner in which the process could fail to meet the process requirements and/or design intent
Using this definition a failure does not need to be readily detectable by a customer to still be considered a failure.
7/18/2007
23
FMEA
How can the process/part fail to meet specifications/requirements? Regardless of the engineering/requirement specs., what would the customer consider objectionable? When this operation is being done, what could go wrong? Or, what tends to go wrong?

Severity Ranking
Rating of 1 to 10 with 10 being the most severe impact. Use a scale. Use the same scale throughout. To assign this rating, must assume the failure mode has occurred. Assign severity rating for every possible effect. May have to estimate rating.

By giving every Failure Mode a RPN rating, we can now prioritize which failure modes to address now and which failure modes we address later.

REDUCING THE POTENTIAL RISK: First line of defense Eliminate causes of failure so that it does not OCCUR - Implement prevention techniques Second line of defense Reduce probability of OCCURRENCE Third line of defense Improve DETECTION of the failure

FMEA
Disagreements on Ratings?
Use data where possible. Try to come to consensus. If consensus fails:
Team may elect to defer to one of its members. Average individual ratings.
Only average if ratings are close (spread of 2 or 3 points maximum).
