Failure Mode and Effect AnalysisFailure Mode and Effect Analysis

• A Formal Method for Understanding Quality Risks• FMEA is a technique for understanding and prioritizing

possible failure modes (or quality risks) in system functions, features, attributes, behaviors, components and interfaces

• Design something quickly and to a high standard, but then it will not be cheap.

• Design something quickly and cheaply, but it will not be of high quality.

• Design something with high quality and cheaply, but it will take a long time.
