Maintenance FMEAs
Abstract
Carl and Fred discussing the application of FMEAs in support of asset maintenance.
Key Points
Join Carl and Fred as they discuss the subject of FMEAs and Maintenance; and difference between FMEAs done in support of product development (Design FMEAs) and FMEAs done in support of maintenance or Reliability Centered Maintenance (RCM) programs.
Topics include:
- Design for Maintainability; Design for Service
- Causes in Design FMEAs are taken to the level of potential design deficiencies
- Causes in Maintenance FMEAs are taken to maintenance actionable level
- Recommended actions in Design FMEA support design improvements
- Recommended actions in Maintenance FMEA support maintenance improvements
- How should Design FMEAs and Maintenance FMEAs be connected?
- RCM Decision Logic Diagrams in Maintenance FMEA vs Effect descriptions in Design FMEA
- Reliability professionals should understand both product development and operations
- Be aware of failure rate handbooks, and the assumptions that go into the information
- Put an asterisk on failure rate data that is from handbooks
Enjoy an episode of Speaking of Reliability. Where you can join friends as they discuss reliability topics. Join us as we discuss topics ranging from design for reliability techniques to field data analysis approaches.

That is a great discussion. In the company I work for we “messed up” with the classical RCM logic and we do consider “failure Elimination” strategies as the first question in the logic diagram. It means that we explore the root cause of the failure and address action from improving procedures and operating discipline in general to redesign.
Thanks for the comment, Luiz. Failure elimination, where possible, is an excellent first option. In some maintenance projects, it may not be possible, or may not meet cost-benefit hurdles. But, when it can be done, it should definitely be considered.
