PROTOCOLREFERENCE OUTLINE

Process Validation (PPQ) Protocol

Stage 2 Process Performance Qualification protocol with CQA/CPP linkage, enhanced sampling, per-attribute acceptance criteria, and statistical evaluation. Follows the FDA 2011 lifecycle and Annex 15.

What a template is not

A template is a document baseline to adapt inside your own quality system. SPEQ does not approve, validate, or take responsibility for what you issue from it, and using one is not evidence of compliance.

PURPOSE

A Stage 2 protocol confirming, under commercial manufacturing conditions, that the process consistently produces product meeting its quality attributes. PPQ is not a demonstration that three batches passed; it is the point at which the control strategy developed in Stage 1 is tested at scale, with sampling intensity high enough to characterise variability rather than merely to release.

What's Inside

✓Process description and the control strategy carried forward from process design
✓Critical quality attributes, critical process parameters, and the in-process controls linking them
✓Enhanced sampling and testing plan, with the sampling intensity justified against expected variability
✓Per-attribute acceptance criteria, distinguishing release specification from the tighter PPQ criterion where one applies
✓Equipment, facility, utility, and analytical-method qualification prerequisites that must be complete before execution
✓Execution and data-capture arrangements, including who may authorise a deviation mid-run
✓Statistical evaluation, conclusions, and the continued process verification plan that follows

How to Use It

1Summarise the Stage 1 control strategy first — PPQ tests that strategy, so an unstated strategy cannot be tested
2Justify the sampling intensity against expected variability rather than defaulting to release sampling
3State per-attribute acceptance criteria in advance, and say where a PPQ criterion is tighter than the release specification and why
4Confirm every qualification prerequisite is closed before execution; a PPQ run on unqualified equipment proves nothing
5Execute under genuinely commercial conditions — routine staff, routine shifts, routine materials
6Evaluate statistically, and define continued process verification before the protocol closes rather than afterwards

REGULATORY CONTEXT

FDA's Process Validation guidance (2011) frames validation as a three-stage lifecycle in which Stage 2 comprises facility and equipment qualification and process performance qualification, with sampling and testing more extensive than routine. EU GMP Annex 15 sets comparable expectations and requires a validation protocol with predefined acceptance criteria. Neither prescribes the number of PPQ batches; that is a risk- and data-based determination belonging to the organisation, and the protocol is where its justification is recorded.
