Failure Mode and Effects Analysis

  • Analytical technique and systemized group of activities.
  • Means to assure that potential failure modes and their associated cause and mechanism, have been   addressed through earlier detection of types of failure   modes, failure causes and their effects.
  • A tool for design and process engineers.
  • An interactive and never ending process.
  • Technique of reducing risk or avoiding risk.
  • A living document.
  • “Before-the-event” action NOT an “After-the-fact“ exercise.
