The IATF has seen situations where a certification body issues a major nonconformance to a client for not achieving their customer’s performance indicators (i.e. delivery and/or quality) or due to an IATF OEM special status condition. The certification body suspends the client’s IATF 16949 certificate and conducts an onsite special audit. During the onsite special audit, the certification body can verify effective implementation of the identified corrective actions, but not enough time has passed to see the actions have led to the achievement/improvement of the customers performance indicator(s). This new requirement gives the certification body flexibility to revisit the client’s site within a reasonable timeframe after the first special audit to verify sustainable improvement in the customer reports/scorecards.
