Definition:
Failure Modes and Effects Analysis (FMEA) is a systematic method for identifying potential failure modes, their causes and effects on system operation.
Key Points:
- Helps identify single points of failure.
- Used extensively during design and SIL verification.
Example:
An FMEA identifies that failure of a pressure sensor may disable a high-pressure trip function.
