What is FMEA?

FMEA (Failure Mode and Effects Analysis) is the preventive risk analysis of possible failure modes and their effects. In the industrial environment, it is used to manage quality risks systematically and make decisions traceable.

Scientific background

The methodological foundation is based on statistical and process-oriented concepts. Central is the AIAG-VDA logic with causes, effects and action priority. CT data can supplement these systems with internal component information and thereby increase evidence quality.

Relevant key metrics

  • Effectiveness of the method against defined KPIs and target values.
  • Reaction time between deviation detection and stable correction.
  • Sustainability of measures across multiple production cycles.

Standards and thresholds

  • Standards: AIAG & VDA FMEA Handbook (FMEAAV-1, 1st Edition, 2nd Printing, published Aug 2022).
  • Typical thresholds (in practice): Action Priority “H” requires mandatory measures; open high-risk items before SOP typically = 0.
  • Validity: Risk assessment remains team- and context-dependent and must be cross-checked with field data.

Application in industrial practice

  • Risk reduction during development and series ramp-up.
  • Standardised decision processes across functions and sites.
  • Linking quality-related evidence to customer requirements.
