Improving System Safety with Message-Level Software FMEA

System reliability and safety can be improved by applying failure modes and effects analysis (FMEA) to system software. FMEA at the message level can assess effects of many problems caused by low-level faults such as coding errors, timing problems, hardware failure, and unexpected input data.

Topics covered:

  • Introduction
  • Developing a Message-Level Software FMEA
  • Development of Failure Modes
  • When the Needed Information isn't There
  • Closing the Loop
  • A Message-Level Software FMEA Worksheet
  • Suggestions for the FMEA Worksheet
  • Completing the Safety Analysis
