Every new bioreactor or pouch sealer in a regulated plant has to prove itself on paper before it makes anything a patient will use. The proof starts with three test plans, called IQ, OQ and PQ protocols, which fix each test and its pass mark in advance. Much of the time spent on one goes to finding the right documents and copying numbers out of them, and that is the part software can now draft for a person to check.
This guide is for validation engineers and leads, automation and process engineers, quality assurance (QA) approvers and site quality heads at drug, biotech, device and contract manufacturing companies. It also serves leaders deciding whether to automate the paperwork. No background needed.
Imagine you are a validation engineer at a plant in Leiden that makes medicines from living cells. This week's job is OQ-BR204-001, the operational qualification protocol for BR-204, a new 500 liter bioreactor, the tank that grows those cells. Its installation record was approved on September 18, 2026. Fourteen user requirements sit behind the protocol, it holds 31 test steps, and you have been copying setpoints, the values the machine is told to hold, out of a 46-page supplier specification.
At 9:02 am on October 6, a new revision of the requirements arrives, approved by your head of quality. One line on page 4 has changed. A new cell line needs the tank to drop to 28.0 °C on day 5, and QA has tightened temperature control. Before anyone runs a test, you have to say which tests that line touches.

Good protocol work catches this at the desk. Missed, a test passes against a limit nobody holds anymore, or a deviation, a recorded departure from the plan, opens on the floor with the bioreactor occupied.
IQ, OQ and PQ protocols: what they prove, what they are written from and where the paperwork fails
This part names no product. It explains the work, the rules as they stand in November 2026, the arithmetic behind an acceptance range, what FDA has written up, and what regulators say about AI drafting these documents. The bioreactor in the example is fictional, and the rules and letters are real.
01 · In plain words
A machine earns its place in a plant through documents written before it runs
A drug plant buys a bioreactor, a steel tank that grows the living cells that make a medicine. A device plant buys a heat sealer that closes sterile pouches. Neither machine may simply be switched on and used. Regulators expect the company to show, with records, that this machine is fit for this job. Showing it for a machine is called qualification. Showing it for a whole manufacturing process is called validation, and qualified equipment is one of the things process validation stands on.
The proof comes in three stages with three short names. Installation qualification, or IQ, checks that the machine was installed as designed. Operational qualification, or OQ, checks that it runs across its full range. Performance qualification, or PQ, checks that it does the real job under real conditions. Each stage starts with a protocol: a test plan that lists every step, the expected result and what counts as a pass. People approve the plan first, so nobody can pick the pass mark after seeing the answer.
Writing that plan looks like engineering, and part of it is. Much of it is clerical. The author opens the company's locked template, then goes hunting. The operating range is in the user requirements. The drive limit is in the supplier's design specification. The instrument tag is in the installation report. The reference thermometer's accuracy and due date are on a calibration certificate. Each value is found, read in context and retyped with its unit.
Then a table has to tie every requirement to the tests that prove it, usually in a spreadsheet beside the protocol. And the sources keep moving. A requirement gets a new revision, or a drawing does. Someone has to work out which tests just went out of date, usually by reading the protocol again. Validation document automation means software that does the finding, copying and comparing, cites the page for each value, and leaves the decisions and signatures to qualified people.
How a bioreactor goes from a written requirement to staying qualified
Say what you needThe site writes a user requirements specification, or URS: ranges, tolerances, alarms, what the machine must do.
Check the designThe supplier answers with a functional and design specification. The site checks the design against the URS, and may test at the factory.
Write and approve the protocolsIQ, OQ and PQ plans are drafted from those approved records, with a trace back to each requirement. This step is the subject of this guide.
Run and recordPeople run the tests on the machine and record actual results. Anything off plan becomes a deviation. A report sums it up against the acceptance criteria.
Keep it trueEvery later change to the machine, its requirements or its software is assessed for what it does to the qualified state.
Step 3 is the subject of this guide, and changes in step 5 send people back to it. The people, plant and figures in the example are fictional.
Surprises in qualification paperwork, from FDA's missing labels to a value that exists nowhere
FDA's drug rules never say IQ, OQ or PQ
21 CFR 211.63 asks for equipment of appropriate design "for its intended use", and 211.68 for routine calibration and checks.1,2 The three labels come from common practice and two other texts: EU Annex 15, the EU's manufacturing rules on qualification and validation, and ICH Q7, the international guide for active ingredients.3,4 FDA's warning letters, its notices of what it believes are significant violations, use the labels with drug makers all the same.5,6,7
The plan comes before the test, and a change to it has a price
Under Annex 15, a significant change to an approved protocol during execution "should be documented as a deviation and be scientifically justified".3 A number fixed at the desk costs an edit. The same number fixed on the floor costs an investigation.
A perfect test could count for nothing in Europe
The draft revision of EU Annex 11 says test cases not traceable to requirements or specifications "do not meet the requirements to qualification and validation".8 It is a draft and covers computerized systems, but it shows where inspectors' thinking has gone.
The value you need may exist nowhere
In the example, the supplier's alarm table leaves the high dissolved oxygen setpoint "to be set at commissioning", the equipment's setup and first start. No copying fixes that, and someone has to decide. By hand, gaps like this tend to surface late, when the test step has no expected result to write down.
URS, protocol, acceptance criterion and trace matrix: the words on every page
URS
User requirements specification. Annex 15 calls it "a point of reference throughout the validation life cycle".3 It says what the machine must do, in the site's words.
Protocol
The approved test plan for a stage. Annex 15 asks that it define "the critical systems, attributes and parameters and the associated acceptance criteria".3
Acceptance criterion
The result that counts as a pass, fixed in advance. In the example: the temperature probe reads 36.7–37.3 °C at a 37.0 °C setpoint.
Trace matrix
A table linking each requirement to its specification clause, its design record and the tests that prove it. Also called a requirements traceability matrix, or RTM.
IQ vs OQ vs PQ: what each stage proves, and which document it answers to
In shortIQ asks whether the machine was installed as designed, OQ whether it runs across its range, and PQ whether it does the real job. EU Annex 15 lays out the stages from requirement to performance, and it lets a site combine them where that is justified.
Annex 15 runs from a written requirement to a performance test, and each stage is released before the next

ICH Q7, the good manufacturing practice (GMP) guide for active ingredients, gives the shortest definitions. IQ is documented verification that equipment "as installed or modified" complies with the approved design, the manufacturer's recommendations or user requirements. OQ shows it performs as intended "throughout the anticipated operating ranges". PQ shows that equipment and its ancillary systems, connected together, "can perform effectively and reproducibly".4
FDA's 2011 process validation guidance describes the same work with no labels: verifying equipment is built and installed to the design, and verifying it operates "in all anticipated operating ranges".9

Runs with product or a proven substitute, for a later protocol
The pairing in the third column is how PIC/S, the inspectors' co-operation scheme, tells inspectors to read a computerized system's file: "PQ versus URS", "OQ versus FS" and "IQ versus DS or DR".10 Many sites apply the same pairing to equipment.
Qualification vs validation, and how a device maker's process validation uses the same three letters
In drug manufacturing, equipment is qualified and processes are validated, and Annex 15 says computerized systems "should also be validated according to the requirements of Annex 11".3 FDA told one drug firm that qualification of equipment "is an integral part of your process validation program".6
Device makers use IQ, OQ and PQ for process validation itself. FDA's 2015 device training slides describe IQ as whether "everything" is "installed correctly" and OQ as challenging process parameters to assure the process makes product that meets requirements, with a heat sealer as the worked case. They draw on a 2004 Global Harmonization Task Force guidance, which we read only through these slides.11
Since February 2, 2026 the device rule is the Quality Management System Regulation (QMSR), which incorporates ISO 13485:2016 by reference.12 FDA's device inspection program now lists validation of processes under clause 7.5.6 of that standard.13 So a site that runs both kinds of product can hold two sets of rules over one document format.
What an OQ protocol template contains, section by section
WHO's guideline on qualification says a protocol should specify prerequisites and test details, including acceptance criteria, and a report should follow each protocol or stage.14 Annex 15 adds approval by the appropriate people, critical parameters, and a formal release to the next stage.3 The rest is house style, held in a locked template. The example's OQ template has 21 sections:
Locked wording, the URS title and revision, the site's validation master plan
The machine
System description, prerequisites, test instruments
IQ report, drawings, calibration certificates
The tests
Alarms, temperature, agitation, dissolved oxygen, pH, pressure, gas flow, power-failure recovery, access and audit trail
URS for what is asked, design spec for limits, the author for how to prove it
The close
Deviations, acceptance and conclusion
Locked wording
Scaling the file to risk. Annex 15 says decisions on the scope and extent of qualification should rest on "a justified and documented risk assessment".3 The commissioning and qualification guide from ISPE, the pharmaceutical engineering society, second edition, June 2019, is sold, so we read its publisher's page, which describes a system risk assessment that identifies critical aspects and critical design elements.15 A protocol that tests everything because nobody decided what mattered costs time twice, once to write and once to run.
03 · The source records
The six records behind one OQ protocol, and which values each one supplies
In shortAn OQ protocol quotes other controlled documents. In the example, six records and 157 pages supply 19 values and every requirement. Before copying anything, the author has to establish that each record is the current approved revision.
Most of the reading behind the example's protocol is the supplier's paperwork

P&ID means piping and instrumentation diagram. A seventh record, the alarm list of a matching bioreactor called the sister unit, enters the example only as a suggestion, in section 8.
Why copying a setpoint from a design spec takes longer than it sounds
The value has to carry its unit exactly as written, because "60 % air saturation" and "60 %" are different claims. It may sit in a table with a footnote that changes its meaning: the example's alarm table notes that its setpoints are defaults for the 37.0 °C recipe. It may be scanned. It may differ between revisions, and a superseded copy may be the one in someone's folder. The author also has to check it against every other source that mentions it, which is how a disagreement gets found.
Annex 15 says the inter-relationship between documents in complex validation projects "should be clearly defined", and that appropriate checks should ensure "the integrity of all data obtained".3 For documents held in computer systems, 21 CFR 211.68(b) requires that input and output "shall be checked for accuracy".2 A site's own procedure often turns this into a second-person check, which adds that person's hours. Part 211 sets no format for that check, and the degree of verification depends on the system's complexity and reliability.2
04 · The rules and their dates
Annex 15, 21 CFR 211, ISO 13485: who asks for qualification and in what words, as of November 2026
In shortEU Annex 15 is the fullest text and has stood since 2015, with a revision planned: a draft in December 2026 and publication in April 2028. FDA binds drug makers through Part 211 and explains itself in a 2011 guidance. Device makers moved to ISO 13485 under the QMSR on February 2, 2026. The draft EU Annex 11 and Annex 22 are still drafts.

Where FDA's Computer Software Assurance guidance fits. The current version, February 3, 2026, covers "computers or automated data processing systems used as part of production or the quality management system for medical devices".19 It concerns software. It does not govern the qualification of a drug plant's bioreactor. For a device maker it does reach production and quality system software, and its risk framework names "artificial intelligence/machine learning tools" when used that way, so a drafting tool in a device maker's quality system may itself fall in scope.19 CDER, FDA's drug center, has issued no counterpart; its July 2026 agenda lists a planned supplement on AI-based systems, and an agenda does not bind CDER to publish it.28 The computer software assurance guide covers that method in full.
GAMP 5, second edition, July 2022, is ISPE's industry guide for computerized systems. It is sold, and we read only its publisher's page, so this guide quotes no requirement from it.29 It has no force of law.
05 · The trace matrix
The requirements traceability matrix: what each column proves and why it drifts from the protocol
In shortA trace matrix links each requirement to its specification clause, its design record and its numbered tests. EU Annex 11 asks for traceable requirements today, and draft Annex 11 names the matrix. The rows that repay the effort are the ones that show a gap or a disagreement.
Read forward, a trace matrix answers the approver's question: is every requirement proved somewhere? Read backward, it answers the inspector's: why is this test here? In equipment work it has more than two links, because a requirement written by the site is answered by a supplier's clause, built as a design record and proved by a test.

What Annex 11, FDA and PIC/S say about tracing requirements to tests
None of the texts in force calls for a document named "traceability matrix", and each one wants the links.
EU Annex 11, section 4.4: "User requirements should be traceable throughout the life-cycle."16 It applies to computerized systems.
EU Annex 15, section 3.2: the URS "should be a point of reference throughout the validation life cycle", and 3.3 has its requirements verified during design qualification.3
Draft EU Annex 11, sections 6.5 and 9.5: "Documented traceability between individual requirements, underlaying design specifications and corresponding qualification and validation test cases should be established and maintained", "e.g. by means of a requirements traceability matrix".8 It is still a draft.17
FDA, General Principles of Software Validation (2002, devices): a software requirements traceability analysis "should be conducted", and requirements should be "measurable or objectively verifiable".30
PIC/S PI 011-3, for computerized systems: inspectors look for evidence that qualification testing "has been linked with the relevant specification's acceptance criteria", and for "the traceability of actions, tests and the resolution of errors and deviations". Then: "If the firm has not got proper change and version controls over its system life-cycle and validation documents, then the validation status is suspect."10
Four ways a spreadsheet trace matrix falls out of step with its protocol
What happens
What goes wrong in the matrix
A test is renumbered. Section 9.2 gains a step.
Rows now point at the wrong test, and nothing shows it.
A source gets a revision. The URS goes to revision 4.
The header still says revision 3, so links point at wording that has changed.
A matrix is copied from a sister unit's protocol.
The other unit's clause numbers come along.
A cross-referenced protocol is reissued.
A requirement "tested elsewhere" now points at a superseded document.
One cause sits behind all four: the protocol is edited as a controlled document, and the spreadsheet is edited from memory. A matrix that is an appendix of the protocol is approved and superseded with it. It also has to be traced to numbered test steps, because a requirement traced to "section 9.2" forces a full re-read of that section when anything moves.
06 · The arithmetic
Working out an OQ acceptance range on a ±0.3 °C requirement
In shortThe sums are short. A setpoint plus or minus the tolerance gives the expected reading. The test limits come from the range. The design and the reference instrument both have to be good enough for the new tolerance. In the example, tightening control moves three numbers and leaves others standing.

Annex 15 asks OQ to include tests "to confirm upper and lower operating limits, and /or 'worst case' conditions", which is why a new low end of 28.0 °C changes a test step even though the everyday setpoint is unchanged.3 The thermometer row's accuracy ratio is the tolerance divided by the reference instrument's accuracy: how much finer the instrument is than what it checks. The ratio has no fixed value in the texts this guide cites. Your calibration procedure sets the ratio you accept, so a protocol should state it and name the certificate.
Three smaller sums that catch test steps out
Calibration due dates against the run date. The example's portable oxygen meter is due November 20. If tests 9.4-01 to -03 run after that date, they need a newer certificate. The date goes in the plan.
Resolution against tolerance. The example's drive speed displays to 1 rpm against a ±2 rpm tolerance. Round to what the instrument can show, and say so.
Counting coverage. Fourteen requirements, three proved elsewhere, 31 unique test steps. One step can serve two requirements, as 9.2-01 does, so count steps once, and show the sum.
07 · When a source changes
Change impact assessment after a URS revision: how to find the tests it rewrites, and what still holds
In shortEU Annex 15 expects a planned change to be assessed for its effect on documentation, validation and calibration. Compare the new revision with the one each document used, list the linked tests, mark the affected ones and write down what still holds. Approved documents get a new version and are never edited in place.
One changed requirement among 14 comes down to three of 31 test steps to rewrite

Annex 15 says any planned change that may affect quality "should be formally documented and the impact on the validated status or control strategy assessed". Section 11.4 has quality risk management evaluate a change for its effect on "documentation, validation, regulatory status, calibration, maintenance", to plan "any necessary process validation, verification or requalification efforts".3
PIC/S's 2007 recommendation calls commitment to change control "essential to ensure a continued validation status".31 Annex 11 puts the record in the file: validation documents "should include change control records (if applicable) and reports on any deviations".16 FDA's guidance says the qualification plan should include "the firm's requirements for the evaluation of changes".9
Five steps from a new revision to an approved new version of the protocol
Compare line by line, against the revision each open and approved document was drafted from. Those may differ.
List every linked test case, from the trace down to numbered steps.
Mark what must change and say what still holds. The second list matters as much. It is the evidence that you looked: the design range, the reference instrument and the unaffected step.
Redraft in a new version. An approved document stays as it was.
Review and approve again. If the protocol has already run, the question moves to requalification, whether to test the machine again, and any change during execution is a deviation under Annex 15, section 2.7.3

08 · Gaps and disagreements
Specs that disagree and values nobody wrote down: 150 rpm against 140, and an alarm set at commissioning
In shortThree kinds of row stop a protocol: a disagreement between two approved documents, a gap where a test has no value, and a design feature with no requirement. Each needs a named person to decide and a written reason. Software can find them. Picking the answer stays with people.
The requirement asks for 150 rpm, and the design limit and factory test both stop near 140

What to record
Disagreement
URS-022 asks for 20–150 rpm. The design spec limits the drive to 140 rpm at 400 L to stay within shaft torque. The factory test measured 140.4 rpm.
Accept the limit and change the URS under change control, or ask the supplier to meet 150 rpm.
Who decided, why, and whether the process needs 150 rpm at full volume
Gap
URS-031 wants alarms within 5 s. The alarm table leaves the high dissolved oxygen setpoint "to be set at commissioning", so test 9.1-04 has no expected result.
Get the commissioned value, or take the sister unit's value and mark it to verify before the test runs, or type a value with a reason.
The source, who verifies and when. Another unit's value is a suggestion until checked.
Design with no requirement
The design spec includes antifoam dosing with a pump and foam probe. The URS does not ask for foam control.
Add the requirement and test it, or record that the site does not rely on the function.
Whether the batch relies on it. Under draft Annex 11, a test with no requirement behind it would not count.8
A test at the equipment limit leaves the requirement open. Testing at 140 rpm proves the machine runs at 140 rpm, and it says nothing about a requirement for 150 rpm. Annex 15 has the URS as the point of reference, so a limit that falls short of it needs a recorded decision and, where the requirement itself changes, a change to the URS itself.3 The approver should see which of these happened.
Supplier documents have their own rules. Annex 15 lets tests done at the factory stand in for tests on site "where appropriate and justified" and "if it can be shown that the functionality is not affected by the transport and installation". It says the site's people should "confirm suitability and compliance with internal procedures before approval" of a third party's protocols.3
FDA's 2011 guidance leaves the last word with the firm's quality control unit, as section 4 quotes.9 Buying good instruments settles nothing by itself: FDA told one animal drug maker that "merely purchasing measurement instruments does not constitute equipment qualification".32
Borrowing a value from a sister unit has similar logic. Annex 15 allows data from outside a manufacturer's own program "provided that this approach has been justified" with adequate assurance about how it was obtained.3 That clause concerns supporting data, and a site's own procedure should say whether and how a sister unit's setpoint may be used. In practice, the safest form is the one the example shows: named source, named verifier, verified on the panel before the test runs.
09 · What inspectors cite
Form 483 counts and warning letters on equipment qualification and process validation files
In shortA Form 483 lists inspection observations that, in the investigator's judgment, may violate FDA's requirements.33 FDA publishes how often it cites each rule. In fiscal 2025 the device process validation section drew 153 citations and the drug equipment sections drew hundreds. Recent letters to drug makers show document faults in plain view: a qualification protocol that left out the machine in use, a qualification with no comprehensive range of operating parameters, and qualification documents completed after inspectors asked for them.
Process validation is the sixth most cited section on device 483s in FDA's last full year under the old rule

Read these with FDA's own caveats. Not every Form 483 is in the data, since some are manually prepared. A 483 lists observations and can carry several: 2,837 drug citations sit on 713 forms and 2,660 device citations on 791 in fiscal 2025.33 The rows name a rule and a short description, so they cannot say how many concern a protocol. The 820.75 rows count the old rule's last full year. Inspections under the QMSR read ISO 13485 instead.12,13
Seven warning letters to drug makers, and the document fault inside each one
Letter
What FDA wrote
The document fault
736888, September 2, 2026, over-the-counter drug maker
A qualification protocol and report "lacked total organic carbon (TOC) testing, conductivity, or microbial content" to show the system was "fit for its intended use".34
A plan that left out the tests its use depends on
728604, June 12, 2026, animal drug maker
"You failed to provide a comprehensive qualification protocol", and buying instruments did not fill the gap.32
Equipment bought, with no plan behind it
718601, January 7, 2026, drug maker
An "executed metal detector qualification protocol did not include the qualification of the metal detector MFG-1276", which inspectors found not working.35
A file that misses the machine in use
711191, September 23, 2025, drug maker
"Process validations for both drug products were last executed in 1999", despite later formula changes.36
Changes that never reached the validation file
704786, June 12, 2025, drug maker
Investigators saw the "quality assurance manager generating and completing equipment qualification documents investigators previously requested".37
A record written after someone asked for it
700242, April 16, 2025, active ingredient maker
One passage says a qualification "lacked a comprehensive range of operating parameters". Another says a qualification lacked "evaluation of operating conditions for different flow rates or product throughput".38
Limits not proved
610444, March 10, 2021, drug maker
The firm "did not have installation qualification and operation qualification documentation for your manufacturing equipment".6
No qualification record at all
Each letter also carries other findings. A warning letter records FDA's view of one firm at one time, and we cite each only for what it says.
Why qualification documents go wrong: eight common causes
The error
Why it happens
What catches it
A value copied wrong, or into the wrong field
Long retyping across six documents

A value from a superseded revision
A local copy from last quarter
One current-revision list, checked at draft time and again at approval
A requirement with no test
The matrix was built after the protocol
Building the trace first
A test with an impossible range
Limits retyped by hand with nothing to test them, for instance columns swapped
A simple rule: lower must be below upper, inside the design range
Limits never challenged
The template's default setpoint stayed in
A review question: which test proves each limit?
An instrument out of calibration on the run date
The due date sits on a certificate no one rereads
Due date against planned run date
A protocol copied from a sister unit
Speed: the structure is right and the clause numbers are not

A change that never reaches the file
No link from the change record to the tests
Requirement-to-test links read at each change

10 · What a wrong number risks
What a wrong number in a protocol puts at risk: copying error rates, failed runs and late equipment
In shortNobody has published a copying error rate for qualification protocols. Studies of single-entry typing in other settings run from about 3 in 1,000 to 37 in 1,000 values. A wrong value becomes an expected result nobody can meet, or a test that passes against the wrong limit. The first costs days and the second is worse, because it stays hidden.
How often people mistype data depends heavily on how they do it

Queue time is the cost that seldom reaches a budget line. Equipment waits for its protocol, a protocol waits for a reviewer, and a project waits for release to the next stage under Annex 15, section 2.10.3 Nothing public measures that delay for qualification. A week of delay on one machine can matter more than the engineer's hours, and only your project plan can price it. Part C shows how to find your own figure.
11 · Digital validation and the market
Paperless validation reached 58% of organizations in one vendor's survey, while protocol hours stay unmeasured
In shortOne validation software vendor's surveys are the main public numbers. Digital validation systems jumped from 30% to 58% of organizations surveyed in a year, and most respondents report rising workloads. Market size and hours per protocol have no measured public figure, so treat any you see with care.
More than half of the organizations in one vendor's survey now run a digital validation system
58 in 100
organizations use a digital validation system in the 2025 survey, up from 30 the year before. Vendor survey, over 300 professionals.
The same vendor's 2024 survey has 60% of respondents saying validation consumes "8% to 10% or more of their project budgets", and 48% organizing validation site by site.42 Its 2025 report has 16% using AI in validation and 46% with no current plans.41 The 2026 report, as sponsored content, has 614 respondents, 39% "already using or evaluating AI for validation" and 78% confident it will be standard by 2030.43
These come from a firm that sells digital validation, so read them as direction and allow for who answered. The 16% and the 39% ask different questions and do not make a trend.
What paperless validation changes, and the part it leaves with the author
A digital validation system generally replaces paper in execution: electronic test steps, captured results, routed approvals, and a trace generated from links people enter. That removes wet signatures and missing pages. A value still has to reach the system from a PDF, and a person usually types it.
Drafting from source records and redrafting after a change are a separate job, and a site can buy one, the other or both. On the vendor pages we read, most AI claims about protocol generation carry no method, so this guide quotes none of them.

12 · AI and its limits
Can AI draft a qualification protocol? Draft Annex 22, FDA's letter on AI documents and the review duty
In shortNo text in force that we read forbids a drafting aid, and none approves one. Draft EU Annex 22 says generative AI "should not be used" in critical GMP applications, and that qualified people answer for outputs elsewhere. FDA has told one firm it must review AI-generated documents. Whether a protocol draft is critical is your own documented assessment.

Draft. EudraLex Volume 4 lists no Annex 22 on November 3, 202617,22
Generative AI and large language models (LLMs) "should not be used in critical GMP applications". In non-critical uses, "personnel with adequate qualification and training should always be responsible for ensuring that the outputs ... are suitable for the intended use".
If this stands, you assess whether your use has "direct impact on patient safety, product quality or data integrity", and document it.
EMA workshop report, EMA/156789/2026
Workshop of June 30, 2026. No revised text published47
Comments supported allowing LLMs in GMP applications. The drafting group "has therefore discussed" widening the scope under a fully documented, risk-based control strategy, and concerns remain.
The wording may move. Inspectors' target for final text is Q4 2026, with no adoption date.18
"If you use AI as an aid in document creation, you must review the AI generated documents to ensure they were accurate and actually compliant with CGMP", under 21 CFR 211.22(c). CGMP means current good manufacturing practice.
No statement of general policy, and a clear signal about who answers for the result.
Does not address AI "used for operational efficiencies (e.g., internal workflows, resource allocation, drafting/writing a regulatory submission)" that do not affect patient safety, drug quality or study reliability.
Aimed at AI behind regulatory decisions. A protocol-drafting aid is more plainly a CGMP question under Part 211.
Manufacturing AI should follow quality risk management and ICH Q8, Q9 and Q10, "awaiting revision of current regulatory requirements and GMP standards".

Timing for high-risk categories.
A separate legal question from GMP. Ask counsel where a tool sits.
Where AI drafting goes wrong in a protocol, and why a reviewer may miss it
A model can state a value that appears in no source, called a hallucination, or leave one out. One company's own study on generating clinical notes reports a 1.47% hallucination rate and a 3.45% omission rate across 12,999 annotated sentences. All its authors worked for that company, the setting differs, and it reports the rates falling as prompts and workflows improved.53 It shows why every value needs a page a reviewer can open.
The second risk sits with the reader. Automation bias is the tendency to over-rely on automated output. A systematic review drew 74 papers from 13,821 retrieved and found that workload, task complexity and time pressure feed it, and that training and emphasizing the user's accountability reduce it.54 A clean draft reads as correct. A site that replaces four days of copying with ten minutes of skimming has lost the checking it used to get by accident.
Controls that make an AI draft reviewable in a GMP file
No value without a source page, so an unread or missing value stays empty and flagged.
Locked wording stays locked. Approved template text changes only through its own change control.
Superseded revisions are never a source, and the revision used is recorded per section.
Only a person clears a flag, accepts a draft or signs, with name, date, time and meaning.27
Every step is on an audit trail, in line with 21 CFR 11.10(e) and the ALCOA+ data integrity principles the UK regulator MHRA describes: attributable, legible, contemporaneous, original, accurate, plus complete, consistent, enduring and available.26,55
Your own intended-use and risk assessment of the tool, and your validation of your use of it. A tool used in a GMP activity is a computerized system, and that work stays with the regulated company.16,22
Reviewer measures. Seed known errors in a pilot draft and count what reviewers catch.
13 · How teams do it today
Four days on one OQ by hand: what the author, reviewer, QA and supplier each do to a protocol today
In shortA validation engineer writes, an automation or process engineer checks the content, QA approves, and a validation lead owns the templates. By hand, the example's OQ takes four working days, and only one of them is test design. Teams work from Word and spreadsheets, a digital validation system, consultants, or a mix.
Typical roles
VE
Validation engineer
Writes protocols and reports, usually several at once, from a queue set by project dates.
Cares about: more hours on test design and fewer on transcription.
AE
Automation or process engineer
Reviews test content, knows what the machine does, confirms commissioned values on the panel.
Cares about: being told which tests changed.
QA
QA approver
Approves requirement revisions and protocols before execution, and answers to inspectors for both.
Cares about: seeing every requirement traced before signing.
VL
Validation lead
Owns the master plan and locked templates, sets the rules, and watches the queue.
Cares about: templates changing only through change control.
SP
Supplier or commissioning contractor
Supplies the design spec and factory test report, and sometimes drafts protocols that the site must confirm under Annex 15, section 2.6.3
Cares about: handover dates, and acceptance of the factory results.

14 · One protocol, one change
A 28.0 °C requirement reaches three test cases: the OQ-BR204-001 redraft, step by step
In shortLena Ortiz, the validation engineer, starts from the trace matrix. It shows one gap and one disagreement before she reads the protocol. A new URS revision arrives at 9:02 am.

1
The trace matrix comes before a word of the protocol
Every requirement in URS-BR204 runs across to its functional spec clause, its design record and the test cases that prove it: 14 requirements and 31 test steps. Nine are traced end to end, three are tested in their own approved protocols, one needs a decision and one is a gap. Each cell is a link with its evidence.
The trace matrix. The banner reports the new revision. On the right, URS-031: the alarm table leaves DO_HI, the high dissolved oxygen alarm, "to be set at commissioning", so test 9.1-04 cannot state its expected result.
2
The requirement says 150 rpm and the design spec says 140
The consistency checker marks URS-022. The design spec's clause 6.3, on page 15, limits the drive to 140 rpm at the 400 L working volume because of shaft torque. The test runs at the equipment limit until Lena decides: keep 140 rpm, or ask for a URS change. As Part A says, keeping the limit should come with a recorded reason, and a true change belongs in the URS.
Specs that disagree. Both documents are approved. The screen shows the clause, the full chain and the two choices.
3
"Show what it changes": three test cases turn amber and one stands
Revision 3 and revision 4 sit side by side. Test 9.2-02 expects 36.5–37.5 °C where revision 4 needs 36.7–37.3 °C. Test 9.2-03 accepts ±0.5 °C. Test 9.2-04 tests 30.0 °C and misses the new 28.0 °C low end. Test 9.2-01, the fill step, is not affected. The panel also lists what still holds: the controller's 25.0–45.0 °C range and ±0.2 °C accuracy, and thermometer TR-07 at 6:1.
What the change touches. The checker marks and never clears a mark, and it never edits an approved document.
4
Section 9.2 redrafted, with the old wording struck through
Lena clicks "Draft the updated section 9.2". The section writer reads page 4 of revision 4, rewrites the three test cases in the locked template's wording, and shows old and new expected results together. Temperature probe TT-204-01 now reads 36.7–37.3 °C, and steps 2 and 3 repeat at 28.0 and 40.0 °C within ±0.3 °C.
The redraft. Nothing takes effect until the author accepts.
5
She accepts, and the matrix moves to revision 4
The header reads URS-BR204 rev 4, the protocol moves to version 0.2, and URS-021 shows "Traced · rev 4" with its four tests green. The protocol goes to Omar Haddad, the automation engineer, and the step goes on the activity record.
Traced to the new revision. Test 9.2-04 now repeats its steps at 28.0 and 40.0 °C. The agitation row still shows that the specs disagree, because that is a separate decision.
15 · Inside the protocol
From a locked template to a signed OQ protocol: 19 sections drafted, 19 values cited, one still missing
In shortThe protocol moves through four steps on screen: Template, Review, Validate and Output. The author ticks sections and gives instructions in plain English. Software drafts and checks. She decides the missing value and the disagreement, and export waits until she has. Three people then sign, each with a stated meaning.
The screen's step called "Validate" is the author checking values against their sources, and its status reads "Validating" while she does. It is a name for that step. Qualification and validation remain work your own people do and sign.
1
The right template and the current records for BR-204
Templates are approved and locked. The source finder lists six records for this unit, current approved revisions only, with pages and dates. The sample shows the view before revision 4 was accepted.
Pick a template. Version 4.2 of the process equipment OQ has 21 sections. The records add up to 157 pages.
2
Plain English in, locked wording untouched
Lena ticks 19 of the 21 sections. Clean-in-place is marked as having its own protocol, and foam control is suggested because the design spec lists a pump and probe the requirements do not. The run on the right reads six records, drafts the ticked sections, extracts 19 values and builds the trace. The sample reports a draft ready in 52 seconds.
Drafting the sections. Each value in section 9.2 carries its citation, here URS-021 rev 4, page 4. The last step ends amber: one value missing, one where sources disagree.
3
Every value beside its source page
All 19 values are listed with the document and page: 17 matched, one to check and one missing. Clicking a value opens the page with the passage marked. A reviewer opens the same page to check the number.
Every value and its source. The page on the right is the sample's URS, which is fictional. "1 missing, export waits for it" sits at the foot.
4
The missing alarm setpoint stays empty until a person decides
Page 12 of the design spec shows why no source holds it: DO_HI is "to be set at commissioning". The closest match is the sister unit's approved alarm list, at 60% air saturation. Lena can use it and mark it for verification, ask Omar Haddad, or type a value with a reason. In the story she takes 60%, marked for Omar to confirm on panel HMI-204 before test 9.1-04 runs. Another unit's value is only a suggestion until that happens.
A value no source holds. Three choices, each recorded with who and why.
5
The controlled template, with both trace appendices
The protocol is written into the plant's controlled Word template, 38 pages, with Appendix A (requirement to test) and Appendix B (value to source). Blank results tables are ready for execution. Every page carries a draft watermark, marked not for execution, until QA signs. The sample's scope paragraph names foam control, although section 9.10 was only suggested at this point: a reviewer's catch.
The output. Word or PDF/A, the archival form of PDF, with the purpose paragraph now citing URS revision 4.
6
Three signatures, each with its meaning
Lena signs as author at 9:18 am. Omar signs at 9:41 am with the meaning "Reviewed — test content and commissioning values checked". Dr. Maya Chen re-enters her password and approves "for execution" at 10:05 am, and version 1.0 is released. Each signature shows name, date, time and meaning, the elements 21 CFR 11.50 asks an electronic signature to show.27 On screen the controls read "designed to support 21 CFR Part 11 and EU Annex 11", which is the accurate wording: your validation of your own use decides the rest.
Three signatures. Approved protocol, version 1.0. Execution comes next, and it stays with your people.
The approval dialog. It states the document version and the meaning before the password.
16 · The other screens
Source changes, every open protocol, locked templates, the dashboard and the rules QA sets
In shortAround the single protocol sit the screens a validation lead works in: what changed in the last two weeks, what is open at each site, the approved templates, where values came from, and the settings that hold your own rules.
Design with no requirement. Antifoam dosing is in the design spec and missing from the URS. The panel suggests a test, and the next URS revision should say whether the batch relies on it.
Further down the matrix. Test 9.1-04 is red. Audit trail, log-ins and restart have tests of their own, and batch backup points to another approved protocol.
Source changes. The six revisions from section 7, each with what changed and what it touches. Approved documents are never edited in place: a change opens a new version.
Every open protocol and report. Sample equipment at two plants, including a filling line, autoclave, freeze dryer, ultrasonic welder and pouch sealer, so one team can run drug and device-style work in one list.
Approved templates. Nine in the sample, each with a version, owner and approval date. Wording changes only through change control, with the template owner.
The dashboard, on sample data. The by-hand bars are the sample's 2025 document log with an 8-hour day, and the current times are sample figures. Of the 23 flags, 11 are values not found in any source.
Approvers and rules. One default deserves a look when you configure it: "Prefer the equipment limit" lets design limits win over requirements with the author's confirmation. Decide whether your QA wants a URS change each time.
When a source changes. Mark linked tests, draft the update, open a new version, and choose who hears about it.
17 · Who drafts, who signs, results
Who drafts a protocol and who signs it: six agents, three people and what one medtech result says
In shortEach agent has one job and a limit it cannot cross. Only people accept a draft, clear a flag or sign. Sources go in, and a controlled document, a trace matrix and a value-to-source record come out. The one customer result is stated exactly as published, and every other figure is sample or target.
From source finder to change impact checker: what each agent does to a protocol, and where it stops
Agent
Its job
Its limit
Source finder
Finds current, approved records for the equipment and indexes each page.
Never uses a superseded revision as a source. Another unit's records appear only as a flagged suggestion.
Value extractor
Pulls setpoints, ranges, tolerances, tags and dates, with the unit as written and the page and passage.
Never fills an unreadable value. It says so.
Section writer
Drafts each ticked section, and redrafts when a source changes.
Never changes locked wording. A value with no source page stays empty and flagged.
Consistency checker
Compares each value with every source that mentions it: missing, disagreeing, out of range, wrong unit.
Never clears a flag.
Trace-matrix builder
Links requirement to clause, design record and test case, and builds both appendices.
A requirement is covered by a test or a justification, and anything else is reported as a gap.
Change impact checker
Compares a new revision with the one each document used, marks linked tests and lists what still holds.
Never edits an approved document, and never clears a mark.
A formatting step then writes the controlled template and PDF/A, and it keeps the draft watermark on until QA signs.

The customer result, in the words Botminds publishes. "In production at a global medtech manufacturer: 100+ protocols live, four weeks from start, 80%+ automation." The 80%+ refers to the authoring work. That is everything we state about this customer's result. The customer validates: the product drafts, and the customer's people review and approve. Treat it as evidence that the approach can run in production, then test it on your own documents, since your templates and records will differ.
What stays yours: your assessment, your validation and your signatures
The tool's status under the rules. Drafting of this kind relies on generative AI. Draft Annex 22 would keep such models out of critical GMP applications and hold qualified people responsible elsewhere.22 Whether this use is critical at your site, and how you control it, is your documented assessment. Draft text may change.47
Your validation of your use of it. For a device maker this may fall under FDA's Computer Software Assurance guidance; for a drug maker, Annex 11 and 21 CFR 211.68.16,2,19 The platform carries controls that support your compliance: roles, maker-checker separation, signatures, the audit trail and export of it. Botminds is SOC 2 Type II audited, and its information security is managed to ISO 27001.
Reading what you sign. Citations make checking faster, and the checking is still yours. Plan for the reviewer risk described in section 12.
Part C · Are you ready to automate?
Automating IQ, OQ and PQ protocols at your own site: what copying costs, what it can return and how to test it
You run validation or site quality, or you are waiting on a machine to be released. This part is written for you: where the hours and the risk sit, how to put your own numbers on them, whether your records and procedures are ready, and what to ask any vendor of validation protocol software, including us.
18 · What it costs you
What hand-written protocols cost you: engineer days, re-reads after each change and deviations on the floor
In shortThe direct cost is engineer days, and you are already paying them. The bigger costs tend to sit in the queue in front of the validation desk, the re-reading after each change, and deviations caused by a wrong number. Each can be measured from records you already hold, in about a week.

19 · Your return
What automating protocol drafting returns on your yearly document count
In shortTwo levers can be counted directly: authoring hours and hours spent tracing changes. Three more depend on your records: fewer review cycles, fewer deviations caused by the document and a shorter queue. The calculator takes your numbers, and its defaults are illustrative.

Time saved, valued$0
Net of yearly cost$0
Formulas: authoring hours saved = documents × (hours today − hours after). Tracing hours saved = changes × (hours per change today − hours after). Engineer days = hours saved ÷ 8. Value = hours saved × cost per hour. Net = value − yearly cost. Review cycles, deviations and queue time are left out, and so are hours spent on your first-year template loading and tool validation beyond the yearly cost. Savings only become cash if the freed hours go somewhere: fewer consultants, or a backlog cleared.
Saved hours must not come out of the risk assessment. ICH Q9(R1) is direct about it: "Resource constraints should not be used to justify the use of lower levels of formality in the quality risk management process."57 The saving here comes from copying and re-reading, which no regulation asks for.
A small site may find the net close to zero or negative, and that is a sound answer. At 10 documents a year, the same inputs save 570 hours and leave a net loss of about $48,700, so the case rests on the queue or the risk, or it waits.
20 · Readiness check
Is your qualification program ready to automate? Eight questions on records, templates and review
In shortScore each from 0 to 2. Drafting software reads what you have, so clean revisions, numbered requirements and locked templates matter more than budget.
1
Your yearly protocol count
Do you know how many IQ, OQ and PQ protocols and reports you issue a year, by site and type?
Why it mattersThe count is the multiplier in every sum, and a low one may not repay the effort.
A strong answer"Yes, from the document system, and a capital plan for the next two years."
2
Current revisions, findable
Can someone find the current approved URS, design spec, drawing and certificates for a machine in minutes?
Why it mattersSoftware can only cite what it can reach, and a wrong "current" poisons every value after it.
A strong answer"All in the document system with a status field, supplier documents included."
3
Requirements a test can address
Is each requirement a single numbered, measurable statement?
Why it mattersFDA's software guidance asks for requirements that are "measurable or objectively verifiable".30 One line holding three requirements gives a bundled trace nobody can audit.
A strong answer"Yes on new machines, and we fix legacy URSs when they change."
4
Locked templates with an owner
Are protocol templates approved, versioned and owned, with clear locked wording?
Why it mattersDrafting into a template only works if the template's wording is settled.
A strong answer"One per equipment class, with a named owner and change control."
5
Your trace, today
Does your matrix reach numbered test steps, through the specification and design record?
Why it mattersTracing to a section forces a full re-read, and tracing to a step lets you assess a change.
A strong answer"Yes, as an appendix approved with the protocol."
6
How a change reaches the author
When a source gets a new revision, does the validation author hear, with a record of what was assessed?
Why it mattersAnnex 15, section 11.4, expects the effect on documentation and validation to be evaluated.3
A strong answer"Change control names affected qualification documents, and we can show it."
7
Your position on AI in GMP documents
Has quality decided how an AI drafting aid would be assessed, validated and reviewed?
Why it mattersDraft Annex 22 and FDA's letter 722591 to one firm both leave the review to people, and the final EU text may differ.22,47,46
A strong answer"A written intended use and risk assessment, a review procedure, and someone watching the EU text."
8
A baseline you can defend
Do you have hours per protocol, review cycles and document-caused deviations from your own records?
Why it mattersNo measured public benchmark exists, so without your own numbers a pilot proves nothing.
A strong answer"Yes, from 20 recent protocols and the deviation log."
9
The days you get back · for reflection
If your engineers had three of their four days back on each protocol, what would they do first: design better tests, clear the requalification backlog, or take on work you now send to consultants? Not scored.

Legacy protocols. Will you bring approved documents into the trace, or only at their next change?
Your SOP. Does your documentation procedure need to say what counts as "author" when software drafted the text and a person accepted it?
Regions. If the final EU Annex 22 keeps its wording on LLMs, what would you need to show? Keep your assessment in a form you can update.
Suppliers. Can suppliers send design specs in a form with stable clause numbers, and will you write that into purchase terms?
Device and drug under one roof. If one site runs both, which rule does each template answer to, and who says so?
Requalification. Annex 15, section 4, asks for evaluation at an appropriate frequency. Can the same trace feed your requalification reviews?
23 · FAQ
IQ, OQ and PQ questions: meaning, trace matrices, FDA, Annex 15, AI and paperless validation
In shortThe questions people search about qualification documents, each answered on its own.
What is validation document automation?
It is software that drafts qualification and validation documents, such as IQ, OQ and PQ protocols, reports and trace matrices, from a site's approved requirements, design specs and certificates. It cites the page behind each value and marks the tests a new revision touches. Qualified people still decide open questions, review and sign.
What is the difference between IQ, OQ and PQ?
Installation qualification (IQ) checks that equipment was installed as designed. Operational qualification (OQ) checks that it works across its operating range, including upper and lower limits. Performance qualification (PQ) checks that it performs its real job, consistently, with production material or a proven substitute. EU GMP Annex 15 describes all three and allows combining them where appropriate.
What is the difference between qualification and validation?
In drug manufacturing, equipment, utilities and systems are qualified, and processes are validated. Qualified equipment is a precondition for process validation. Device makers commonly use IQ, OQ and PQ as the stages of process validation itself. Computerized systems are validated under EU Annex 11 or equivalent rules.
Does FDA require IQ, OQ and PQ?
The drug rules in 21 CFR 211 do not use those words. They require equipment fit for its intended use, calibration and checks, and approved procedures. FDA's 2011 process validation guidance describes equivalent activities, and FDA warning letters do refer to IQ, OQ and PQ. Many firms use the labels because EU Annex 15 and ICH Q7 define them.
What should an OQ protocol include?
It should name the equipment, purpose, scope, responsibilities, references, prerequisites and test instruments with their calibration status, then each test step with its action, expected result and acceptance criterion. It should test upper and lower operating limits or worst case conditions, and it closes with how deviations are handled. Approval comes before execution.
Is a requirements traceability matrix required?
The EU and FDA drug GMP texts in force that we read do not demand a document by that name, but the links are expected. EU Annex 11 says user requirements should be traceable throughout the life cycle for computerized systems, and PIC/S tells inspectors to look for testing linked to specifications. Draft EU Annex 11 names the matrix as an example, and it is still a draft as of November 2026.
What happens to a protocol when the URS changes?
The change should go through change control, with its effect on documents and qualification assessed, as EU Annex 15 section 11.4 expects. Compare the new revision with the one the protocol used, list linked tests, and rewrite those affected in a new version for review and approval. Changes during execution are deviations, and after execution the question becomes requalification.
Can AI write a validation protocol?
AI can draft one for a person to check, and no text in force that we read bans that. Draft EU Annex 22 says generative AI and large language models should not be used in critical GMP applications, and that qualified people are responsible for outputs elsewhere; it remains a draft. FDA has told one firm it must review AI-generated documents. Your site should write down its own assessment.
What does draft EU GMP Annex 22 say about LLMs?
Section 1 of the July 2025 consultation draft says it does not apply to generative AI and large language models, and that such models should not be used in critical GMP applications. EudraLex Volume 4 lists no Annex 22 as of November 3, 2026. EMA's report on a June 30, 2026 workshop says the drafting group has discussed widening the scope, with no revised text published.
Does FDA's Computer Software Assurance guidance apply to equipment qualification?
Not as such. The current final version, dated February 3, 2026, covers computers and automated data processing systems used as part of production or the quality management system for medical devices. It is about software and is written for device makers. A drug maker's equipment qualification rests on 21 CFR 211, FDA's 2011 guidance or EU Annex 15.
How long does it take to write an OQ protocol?
We found no measured public benchmark, only vendor estimates with no study behind them. It depends on the equipment, your template and your records. The sample in this guide uses 4 working days by hand for one piece of process equipment, of which about one day is test design. Your document system's dates and a time log on three protocols will give your own number.
What is paperless validation, and does it remove the writing?
Paperless or digital validation means running test steps, results and approvals in software instead of on paper. It removes wet signatures and lost pages. Someone still has to find and enter the values, and to work out what a new revision touches, unless a drafting tool does that part too. One vendor's 2025 survey reports 58% of organizations using a digital system.
How did the QMSR change process validation for medical devices?
The Quality Management System Regulation took effect on February 2, 2026 and incorporates ISO 13485:2016 by reference. Process validation now rests on subclause 7.5.6 of that standard, and 21 CFR 820.75 is no longer in the rule. FDA's Form 483 counts for fiscal 2025 still cite the old section, which was in effect during those inspections.
Can software be validated, GxP compliant or Part 11 compliant out of the box?
No. A product can carry controls that support your compliance, such as audit trails, role separation and signatures with their meaning.

Writing a qualification protocol on one screen: the method, the rule dates and a 14-term glossary
Print this page
In shortThe whole guide on one screen: the method, the rules, the readiness bands and the terms.
The method
Confirm each source is the current approved revision.
Build the trace first, down to numbered test steps.
Name who decides each gap and disagreement, and record why.
Give every value a document and a page.
Test upper and lower limits, and check instruments against the run date.
Approve before execution. Later changes are deviations.
Read each new revision against the one each document used, and write down what still holds.
New version under change control. Never edit an approved document.
Where the rules stand
