Which document describes the processes used for testing in a QC program?

• A. Equipment manual
• B. Statistical method manual
• C. Customer manual
• D. Procedure manual

Answer: (D)

The main idea here is identifying which document governs how testing is actually carried out in a QC program. The procedure manual does exactly that: it provides the step-by-step instructions, responsibilities, and acceptance criteria for performing tests. It tells you how to prepare samples, which controls to run, how to record data, how to handle out-of-spec results, and how to maintain consistency across runs. This creates a repeatable, auditable process that supports training and traceability. The other documents serve different purposes. An equipment manual explains how to operate and maintain specific instruments, not the full testing workflow. A statistical method manual covers the calculations and analysis techniques used to interpret results, rather than describing how tests are performed. A customer manual is intended for external information about products or services, not for internal testing procedures.
