Who is responsible for verifying that Non-conformance report NCR disposition has been properly implemented?

The correct answer isC. Source Inspector. In API source inspection practice, once a non-conformance report NCR has been issued and a disposition such as repair, rework, use-as-is, or reject has been approved, the responsibility forverifying that the approved disposition has actually been implemented on the productbelongs to theSource Inspector. This is consistent with the inspector’s core role in source inspection: to witness, verify, document, and report whether manufacturing and quality activities comply with the approved specifications, drawings, procedures, and disposition requirements.

TheVendor’s Quality Managermanages the supplier’s internal quality system and coordinates corrective actions, but is not the independent verifier for the purchaser’s inspection function. TheInspection Coordinatoradministers scheduling, communication, and inspection planning, yet does not normally perform the physical verification at the equipment level. TheManufacturing Engineermay define or support the technical correction, but implementation verification remains an inspection responsibility. Therefore, after NCR disposition is approved, theSource Inspectormust confirm through examination, records review, and where necessary witness of reinspection or retest that the disposition was properly carried out and closed.
