FMECA and RCA

Ways FMECA and RCA differ:

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