PV
Performance Verification
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.
Documented confirmation that a system, once installed and operating correctly, performs consistently in routine use — with production materials, qualified substitutes or simulated product, at the conditions it will actually run — performed within a verification-based C&Q programme, where it does the job PQ does in a traditional one.
Performance verification is the last of the verification steps that follow installation and operational verification. OV proved the system works across its range; PV asks whether it keeps delivering the required result over time on the real duty — a load pattern, a batch size, a utility demand — and not just once, on a test day.
EU GMP Annex 15 says PQ should normally follow successful IQ and OQ, but may in some cases be performed together with OQ or with process validation. Performance verification carries the same flexibility: where a system's performance is only meaningful on product, the evidence may come from process performance qualification rather than a separate protocol.
"PV" is a practice label, not a term ISPE or the regulation defines, and it is easily confused: elsewhere PV abbreviates process validation or pharmacovigilance. A protocol or plan that uses it should spell it out on first use.
- —Confirms consistent performance in routine use, after IV and OV.
- —Uses production materials, qualified substitutes or simulated product.
- —Covers the intended operating range and worst-case batch sizes; sampling frequency is justified.
- —May be combined with OV or process validation where that is justified.
- —Spell it out: PV also means process validation or pharmacovigilance.
EU GMP Annex 15 (2015) §3.13–3.14 (performance qualification: normally after IQ and OQ, may be performed with OQ or process validation; production materials, qualified substitutes or simulated product; operating range and worst-case batch sizes); ASTM E2500-25; ISPE Baseline Guide Vol. 5, Commissioning and Qualification (2nd ed., 2019).
