CQV
Commissioning, Qualification and Validation
What a definition is not
A definition is SPEQ’s plain-language decode of how a term is used in practice, cited to the documents that define it. It is a practitioner reference, not legal or regulatory advice, it does not replace the definition in the source, and where a regulator’s wording differs the regulator’s wording governs.
The full lifecycle from engineering handover to a validated process: commissioning proves engineering readiness, qualification proves equipment and utilities are fit for intended use, and validation proves the process itself consistently produces conforming product. CQV is broader than C&Q, which stops at qualification.
The distinction is not pedantry. C&Q and CQV name different scopes of work, are staffed differently, and end at different milestones — a project that contracts for "C&Q" and expects process validation in the price has mis-specified its own scope. Commissioning is governed by Good Engineering Practice; qualification and validation are GMP activities carrying quality-unit approval.
Do not confuse CQV with CSV (computer system validation). They are visually similar, sit adjacent on the same projects, and mean entirely different things.
EU GMP Annex 15 (Qualification and Validation, 2015) for the qualification and validation expectations; FDA Process Validation: General Principles and Practices (2011) for the three-stage process-validation lifecycle; ISPE Baseline Guide Vol. 5 (2nd ed.) for the integrated C&Q approach.
