IATF 16949:2016 - Automotive QMS Internal Auditor Free Practice Test — 30 Questions

Question 1

During an internal audit of a supplier\'s manufacturing process for critical engine components, an auditor observes a batch of machined parts that have been identified as nonconforming due to exceeding specified dimensional tolerances. These parts are marked with a \"hold\" tag and are located in a designated rework area. However, the auditor notes that the rework procedure for these specific parts does not include a mandatory final inspection or re-verification step after the corrective action (e.g., grinding to meet tolerance) has been applied. What is the most appropriate action for the internal auditor to take in this situation to ensure compliance with IATF 16949:2016 requirements?

Accepted Answer

Document a nonconformity related to the lack of re-verification of reworked nonconforming product and assess the effectiveness of the overall control process for nonconforming outputs.

Question 2

During an internal audit of a Tier 1 automotive supplier, an auditor discovers that a batch of critical fasteners, identified as having a minor dimensional deviation outside the specified tolerance, was inadvertently shipped to a customer. The deviation does not immediately compromise safety but could potentially lead to premature wear over the product\'s lifespan. The supplier\'s documented procedure for nonconforming product control outlines segregation and rework for products identified before shipment. However, it lacks specific guidance on actions to be taken when nonconforming product is discovered by the customer post-shipment, particularly concerning customer notification and potential field actions. What is the most critical aspect the auditor should focus on to assess the organization\'s compliance with IATF 16949:2016 regarding this situation?

Accepted Answer

Verification of the supplier's process for customer notification and potential recall or corrective action for products already in the field, ensuring it aligns with the impact of the nonconformity.

Question 3

During an internal audit of a Tier 1 automotive supplier\'s manufacturing process for critical braking components, an auditor discovers a batch of machined parts that exhibit dimensional deviations exceeding the specified tolerance limits. The production supervisor indicates that these parts have been segregated in a designated area and that a decision regarding their disposition is pending management review. Which of the following actions by the auditor best demonstrates adherence to the principles of IATF 16949:2016 regarding the control of nonconforming outputs?

Accepted Answer
