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.
Verification of a manufacturing system as a whole — its components acting together, and with the systems it depends on — against the requirements it must meet, rather than equipment item by item. In a verification-based C&Q programme it is the point at which a system is shown fit for intended use and accepted for release.
ASTM E2500 defines verification as a systematic approach to verify that manufacturing systems, "acting singly or in combination", are fit for intended use, have been properly installed and are operating correctly. System verification is that idea applied at system level: a WFI loop, a filling line or an HVAC zone is verified as the integrated thing that serves the process, including its interfaces to utilities, automation and neighbouring systems.
In practice it draws together the installation, operational and performance evidence — much of it from commissioning, FAT and SAT — into one traceable conclusion against the user requirements and critical aspects. Gaps between components, such as a hand-off between two skids or a control loop that crosses two vendors' scope, are where it earns its keep.
"SV" is a practice label, and its exact scope is set by the organisation's C&Q procedures: some use it for the whole verification phase, others for the integrated test that follows component-level verification. It is not a term ISPE or the regulation defines, so the plan that uses it should say which.
- —Verifies the system as an integrated whole, not item by item.
- —Includes interfaces to utilities, automation and neighbouring systems.
- —Traces installation, operational and performance evidence back to the URS and critical aspects.
- —Leverages commissioning, FAT and SAT results rather than repeating them.
- —Scope varies by company; the C&Q plan should define it.
