Commissioning and qualification stopped being two separate projects when ASTM E2500 and the ISPE integrated C&Q model let good engineering practice count as evidence. Under the older approach the contractor commissioned a system and the validation group then re-tested it in IQ and OQ; under the risk-based approach the site decides, from a product and process risk assessment, which system attributes affect quality, and commissioning evidence for those attributes, when generated under the right controls, is leveraged into the qualification record rather than repeated. That puts the installer’s records on the critical path of the qualification. Paul Industries builds pharmaceutical systems so their commissioning evidence can be leveraged, and supports the site’s C&Q program through FAT, SAT, IQ and OQ.
ASTM E2500 in one paragraph
ASTM E2500, Standard Guide for Specification, Design, and Verification of Pharmaceutical and Biopharmaceutical Manufacturing Systems and Equipment, replaces the fixed IQ/OQ/PQ sequence with a verification process driven by product knowledge, process knowledge and risk: define the critical aspects of a system that affect product quality, design and build to them under good engineering practice, verify them with subject matter expert involvement and quality unit oversight, and document the acceptance and release. The FDA’s 2011 process validation guidance and the ISPE Baseline Guide on C&Q describe the same lifecycle. The practical effect is that a well-documented commissioning test becomes qualification evidence and a poorly documented one becomes rework.
What the contractor’s evidence has to prove
| Stage | Contractor record | What it is leveraged into |
|---|---|---|
| Design review | Approved drawings, P&IDs, specifications, design qualification input on critical aspects | DQ or design review record |
| Factory acceptance test (FAT) | Skid, vessel or generator tested at the fabricator against the specification, with witnessed results | IQ/OQ evidence where the test is repeatable and controlled |
| Installation | Material certificates, weld maps and logs, borescope records, slope and dead-leg verification, pressure tests, passivation records, instrument calibration | Installation qualification |
| Site acceptance test (SAT) and commissioning | Loop checks, functional tests, alarms, interlocks, capacity, sanitization and SIP cycle runs, spray coverage | Operational qualification where critical aspects are covered |
| Turnover | The organized package, indexed to systems and critical aspects, with deviations closed | The qualification file |
What makes commissioning evidence leverageable
- Pre-approved test protocols with acceptance criteria written before the test, not results written up afterward.
- Calibrated instruments with certificates traceable to the measurement.
- Trained, identified people executing and witnessing; quality unit involvement where the risk assessment requires it.
- Deviations recorded, investigated and closed, not corrected silently.
- Good documentation practice: legible, attributable, contemporaneous, original, accurate.
- Traceability from each test to the critical aspect it verifies and the requirement it came from.
A commissioning test that meets these conditions is qualification evidence; one that does not is a contractor’s note. The difference is set up before the work starts, in the C&Q plan, and it is why we ask for the site’s plan and templates at mobilization.
Direct-impact, indirect-impact and no-impact systems
The impact assessment sorts systems by whether they contact product or affect a critical quality attribute: WFI, clean steam, product piping, CIP and process vessels are direct impact and get full verification of critical aspects; plant steam to a jacket, chilled water and compressed air to non-product uses are indirect or no impact and are commissioned under good engineering practice without qualification. The installer’s records are scaled accordingly: a WFI loop gets the full package; a glycol loop gets drawings, tests and a commissioning report.
Where the contractor’s scope ends
We generate and organize the engineering evidence, execute FAT, SAT and commissioning under the site’s protocols, support IQ and OQ execution with the crews and equipment the tests need, and close our deviations. The site’s validation group owns the risk assessment, the C&Q plan, protocol approval, PQ and process validation, and the release of each system. Where a site has no C&Q function, we work with its validation consultant; we do not act as the quality unit.
Common failures
Turnover packages assembled after the fact from incomplete records; commissioning tests run before the protocol was approved so they cannot be leveraged; instruments used for tests without calibration certificates; modifications made during commissioning without change control; critical aspects never defined, so everything is qualified at the same depth and the schedule doubles; and the validation group first seeing the system at IQ. Each is prevented by agreeing the C&Q plan, the critical aspects and the document templates before the first weld.

Frequently asked questions
Where does commissioning end and qualification begin under integrated C&Q?
Commissioning is the engineering verification that a system is installed and works as designed, under good engineering practice; qualification is the documented, quality-unit-overseen demonstration that the system’s critical aspects meet requirements for GMP use (IQ, OQ and, for processes, PQ). Under ASTM E2500 and integrated C&Q, commissioning evidence generated under the right controls is leveraged into qualification instead of being repeated.
What is ASTM E2500?
A standard guide for specification, design and verification of pharmaceutical and biopharmaceutical systems that replaces a fixed IQ/OQ/PQ sequence with a risk-based verification process: define the critical aspects that affect product quality, design and build to them under good engineering practice, verify them with subject matter experts and quality oversight, and document acceptance. It is the basis of the ISPE integrated C&Q approach.
How does leveraging work in integrated C&Q?
A single, planned verification effort in which commissioning tests are written and executed so that the results for critical aspects can be used directly as qualification evidence, avoiding duplicate testing. It requires pre-approved protocols, calibrated instruments, identified personnel, good documentation practice and quality unit involvement defined in a C&Q plan before work starts.
What is a critical aspect of a system?
A function, feature or attribute of a system that affects product quality or patient safety, identified from product and process knowledge and a risk assessment: for example WFI conductivity, TOC and temperature control, SIP hold temperature, spray coverage, alarm and interlock function. Verification focuses on critical aspects; the rest is commissioned under good engineering practice.
What is a direct-impact system?
A system that contacts product, provides a product-contact utility or otherwise affects a critical quality attribute, WFI, clean steam, product piping, CIP and SIP, process vessels, classified HVAC, and therefore has its critical aspects qualified. Indirect-impact systems support direct-impact systems and no-impact systems (plant steam to a jacket, chilled water) are commissioned only.
What contractor records go into an installation qualification?
Material certificates indexed to heat numbers, weld maps and logs with borescope records, surface finish reports, slope and dead-leg verification, pressure test records, passivation records with rinse and verification results, instrument calibration certificates, as-built drawings and P&IDs, and the equipment nameplate and vendor documentation, organized by system and critical aspect.
What makes a commissioning test usable as qualification evidence?
A pre-approved protocol with acceptance criteria written before the test, calibrated instruments with traceable certificates, trained and identified executors and witnesses, quality involvement where the risk assessment requires it, deviations recorded and closed, good documentation practice, and traceability from the test to the critical aspect and requirement. Without these it is a commissioning note, not evidence.
What is a FAT and how is it leveraged?
A factory acceptance test at the fabricator of a skid, vessel or generator, executed against the specification with witnessed results. Where the FAT protocol was pre-approved and the tests are repeatable and controlled, its results can be leveraged into IQ/OQ so the tests are not repeated at site, which is why FAT protocols are written with the C&Q plan in mind.
What is a SAT?
A site acceptance test after installation confirming the system performs at site as it did at FAT: loop checks, functional tests, alarms and interlocks, capacity and, for water and steam systems, sanitization and SIP cycle runs and spray coverage. Under integrated C&Q, SAT and commissioning results for critical aspects become operational qualification evidence.
Who owns the risk assessment and the C&Q plan?
The site’s validation or quality function, with engineering and subject matter experts contributing, because the risk assessment depends on product and process knowledge the contractor does not have. The contractor builds and tests to the plan and provides the evidence; it does not act as the quality unit.
Why do turnover packages fail qualification?
Because they were assembled after the fact from incomplete records, tests were run before protocols were approved, instruments lacked calibration certificates, modifications during commissioning skipped change control, or critical aspects were never defined so the package does not map to them. Building the package as the work proceeds against an agreed structure prevents this.
How does change control apply during installation and commissioning?
Any deviation from the approved design during installation or commissioning is recorded, assessed for impact on critical aspects, approved and documented before the work proceeds, so the as-built system matches the qualified design. Silent field changes are the most common reason a qualified system’s drawings are wrong at the next inspection.
What is good documentation practice in C&Q?
Records that are attributable, legible, contemporaneous, original and accurate (ALCOA), with additions dated and signed, corrections single-line with initials and reasons, and no backdating, applied to commissioning records as strictly as to batch records because they become qualification evidence.
How does the FDA 2011 process validation guidance relate to C&Q?
Its Stage 2, process qualification, includes qualification of the facility, utilities and equipment before process performance qualification, and it endorses a risk-based, science-based approach consistent with ASTM E2500. Commissioning and qualification of systems is the foundation on which PPQ runs are built.
What does the ISPE Baseline Guide on C&Q say?
The ISPE Baseline Guide Volume 5 (Commissioning and Qualification) describes the integrated C&Q process: system risk assessment, definition of critical aspects, design review, leveraging commissioning for qualification, and acceptance and release, with roles for engineering, subject matter experts and quality. It is the practical companion to ASTM E2500.
How long does C&Q add to a pharmaceutical project?
Less than the old sequential model when planned: FAT, SAT and commissioning are executed once under approved protocols and leveraged, so IQ and OQ become reviews of evidence plus a limited set of tests. Unplanned C&Q, with duplicated testing and reconstructed packages, commonly adds months.
Can commissioning of indirect-impact systems be lighter?
Yes; that is the point of the impact assessment. Indirect- and no-impact systems are commissioned under good engineering practice with drawings, tests and a commissioning report, without qualification protocols, which concentrates the qualification effort on systems that affect product quality.
What role do subject matter experts play in E2500 verification?
They define critical aspects from product and process knowledge, review designs, approve test approaches and assess results for the systems they know, with the quality unit overseeing the process rather than approving every test. The contractor’s engineers act as SMEs for construction and installation aspects.
What happens when a system is modified after qualification?
The change goes through change control with an impact assessment on the critical aspects, is designed and installed to the same standards with records, and is re-verified proportionately to the change, from a document update to a partial requalification. Installation records for the modification are produced exactly as for the original.
What does Paul Industries provide within a site’s C&Q program?
Design review input, FAT witness and execution, installation records built as the work proceeds, SAT and commissioning under approved protocols with calibrated instruments and identified personnel, turnover packages indexed to systems and critical aspects, IQ and OQ execution support, deviation closure and change control discipline, for water, steam, piping, CIP/SIP, vessel and cleanroom systems.
