Failure Modes and Effects Analysis

Failure modes and effects analysis (FMEA) is a functionality that is used to identify and resolve potential problems in a structure within the manufacturing process.

The FMEA uses occurrence and detection probabilities in conjunction with a severity rating to create a risk priority number (RPN). Failure modes with the highest RPN is considered first for improvement.

The types of FMEA are:

  • System FMEA: When the item is the top level system.
  • Design FMEA: When the item is a subsystem or a component.
  • Process FMEA: When the item relates to a manufacturing process.
Master Data Setup
  1. In the Quality Management Parameters (qmptc0100m000) session, select the Failure Modes and Effects Analysis Implemented check box on the Product Quality Management tab. Specify the value for the Default Series field.
  2. Specify a structure code in the System Structure Codes (qmpqm0101m000) session. A structure is a combination of either a system or a sub-system, and a fault code.
  3. In the Systems (qmpqm0102m000) session, specify the system code .
  4. In the Sub-Systems (qmpqm0103m000) session, specify the sub-system code.
  5. In the Faults (qmpqm0104m000) session, specify the faults.
  6. In the Severity Ranking (qmpqm0110m000) session, specify the severity ranking and the associated severity code.
  7. In the Occurrence Ranking (qmpqm0111m000) session, specify the occurrence ranking and the value associated with occurrence code.
  8. In the Detection Ranking (qmpqm0112m000) session, specify the detection ranking and the value associated with detection code.
