Rules for ISO/TS 16949:2002 Audits

The initial certification audit for ISO/TS 16949:2002 is performed in two stages: 1) Readiness Review and 2) Site Audit. The stage 1 Readiness Review will be one or two days on-site to determine if the organization is prepared for the stage 2 Site Audit.

The following documentation must be provided to the audit team for the Readiness Review:

  • description of processes showing sequence and interaction
  • key indicators and performance trends for past 12 months
  • evidence all ISO/TS 16949:2002 requirements are addressed
  • quality manual for each site to be audited
  • internal audit planning and results for past 12 months
  • management review planning and results for past 12 months
  • list of qualified internal auditors
  • list of customer specific requirements
  • customer satisfaction and complaints status, including customer reports and scorecards

If a Pre-Assessment is conducted prior to the Readiness Review, the pre-audit must:

  • be conducted during a single visit to the site
  • not be considered part of the initial audit
  • not exceed 80% of the stage 2 audit days
  • not use auditors to be on the initial audit team
  • not be used to reduce the audit days requirement

Each Site Audit (initial, surveillance, and recertification) must assess the:

  • implementation of new customers since the last audit
  • customer complaints and the organization response
  • internal audit and management review results and actions
  • progress made toward continual improvement targets
  • effectiveness of the corrective actions since the last audit
  • effectiveness of the QMS in achieving customer and organization objectives

On-site or remote supporting functions, e.g., engineering, contract review, purchasing, and warehouses, must be included in the initial and ongoing surveillance audits. For the initial audit, the supporting functions must be audited before the manufacturing site. The design function, whether on-site or remote, must undergo surveillance audits at least once within each consecutive 12-month period. Other supporting functions must be audited at least once during the life of the certificate, in addition to being assessed as part of the initial and recertification audits.
