What type of inspection verifies the operation just performed?

• A. End-of-line inspection
• B. Post-operation check
• C. In-process inspection
• D. Acceptance inspection

Answer: (C)

Verifying the operation just performed is done during production to confirm the current step produced the correct result before moving on. This is in-process inspection. It provides immediate feedback at the workstation, catching errors right away and keeping the process under control, which prevents defects from propagating down the line. End-of-line inspection, by contrast, looks at the finished product after all steps are done, so it doesn’t verify the last operation as it happens. Acceptance inspection focuses on whether the final product meets requirements for release, often at shipment, rather than validating a single operation in real time. A post-operation check can exist, but the term that best matches verifying the just-performed step during production is in-process inspection.
