The unified AIAG-VDA approach: Planning, Structure Analysis, Function Analysis, Failure Analysis, Risk Analysis, Optimization, and Documentation.

Why FMEA Is Critical for the Automotive Industry

Industry Requirements

  • Core requirement of IATF 16949 quality management system
  • Mandatory deliverable for Customer Specific Requirements (CSR)
  • Required document for PPAP (Production Part Approval Process)
  • Key output of APQP (Advanced Product Quality Planning)

Business Value

  • Proactively identify and mitigate risks
  • Reduce recall and warranty costs
  • Accumulate organizational knowledge and lessons learned
  • Improve product reliability and customer satisfaction
