First steps

  1. Self-assessment questionnaire.
  2. On-site audit of the critical areas.
  3. Decision with conditions and a development plan.

How to measure success

Assessment grade and launch PPM. Record the value before you start, so the effect of every action can be shown.

When these methods are the wrong choice

  • Supplier assessment: Day-to-day performance tracking; use the scorecard.
  • VDA 6.3 process audit: Quick shop-floor checks; use LPA.
  • Run at rate: Quality problems without a capacity question.
  • PPAP: Internal process problems.
  • APQP: Problems in a running series process.
