Ways FMEA and RCA differ:
- FMEA is proactive and RCA is reactive.
- FMEA occurs during development and RCA occurs after-the-fact.
- FMEA prevents errors and RCA satisfies patients or requirements.
- FMEA helps processes to work and RCA changes processes that do not work.
- FMEA encourages good outcomes and RCA changes bad outcomes.
