Distinguish between validation and verification, and provide example for each in a CBM T6 process?

• A. Verification confirms design/specs meet requirements (e.g., verifying dimensions of a component); validation confirms the process/product meets user needs in the actual environment (e.g., validating a manufacturing process's ability to produce conforming items).
• B. Verification is about user needs; validation about design specs.
• C. Validation confirms the product is free of defects; verification confirms the product meets user needs.
• D. Verification and validation are interchangeable.

Answer: (A)

The main idea here is the difference between checking that we built it right and making sure it meets what it’s supposed to do in the real world. Verification is about confirming that the design and specifications are followed and that the product or process adheres to those documented requirements. In a CBM T6 process, verification would be, for example, inspecting critical dimensions of a component to ensure they match engineering drawings or verifying that the process parameters and calibration data align with the design specs. It’s about conformance to the documented criteria.

Validation is the opposite perspective: it asks whether the product or process provides the intended outcome for users in the actual use environment. In CBM T6 terms, validation would involve demonstrating that the manufacturing process (with the condition-monitoring and maintenance triggers in place) can reliably produce conforming items under real production conditions and that the outputs meet user needs, such as reliability, performance, and quality requirements in practice.

That’s why the best choice states verification as confirming design/specs meet requirements (with a concrete example like checking component dimensions) and validation as confirming the process/product meets user needs in the actual environment (with an example like validating a manufacturing process’s ability to produce conforming items). The other options mix up these roles or imply they’re interchangeable, which doesn’t align with how verification and validation function in quality and process assurance.
