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.

Avoiding design failures

Avoiding failures during process planning, production implementation

Timing for commencement

Before or at design concept finalization

Before or at feasibility stage or prior to tooling for production

Period of review

Prior to the first trial run

Prior to any investment

FMEA first completion

Prior to production drawing release for tooling 

Prior to bulk production


  • Identifies potential problems with customer point of view.
  • Predictive & Preventive. (A Pro-active Approach).
  • Prioritizes the variables to be focused.
  • Can be used in conjunction with APQP Process.
