21 CFR Part 11 and Annex 11 compliance consulting for electronic records an inspector can trust.

What it is

What are 21 CFR Part 11 and EU GMP Annex 11?

They are the two texts regulators turn to when a GxP record is created, approved or kept electronically. 21 CFR Part 11, titled Electronic Records; Electronic Signatures, is a US Food and Drug Administration regulation in Title 21 of the Code of Federal Regulations. Annex 11, Computerised Systems, belongs to the EU guidelines on good manufacturing practice in EudraLex Volume 4, published by the European Commission, and applies to every form of computerised system used as part of GMP-regulated activities.

The two come from different legal systems and are worded differently, yet they ask a shared question: can the organisation show that its software does what it should, that only authorised people can change data, that every change leaves a trace, and that an electronic signature means what a handwritten one would? Companies selling into both the US and Europe usually build one programme that satisfies both texts rather than two parallel ones.

Current texts. Part 11 is read in its current form in the eCFR. Annex 11 is the revision of January 2011, in operation since 30 June 2011. A revised Annex 11 was put out for stakeholder consultation from 7 July to 7 October 2025, together with a revised Chapter 4 on documentation and a new Annex 22 on artificial intelligence; the consultation has closed, and as of September 2026 the revised Annex 11 is still a draft, not yet adopted. Build to the text in force and keep the draft in view.

Who it is for

Who needs 21 CFR Part 11 and Annex 11 compliance?

Any organisation whose regulated records live in software: manufacturing execution and electronic batch records, laboratory information systems, chromatography data, document management, ERP modules that release product, and quality systems. Organisations come to Sterling from four starting points:

• A customer or partner audits your data. A marketing authorisation holder, a sponsor or a US distributor sends a questionnaire on audit trails, access and validation, and your answers need evidence behind them.
• You are preparing for a regulator. A pre-approval, licensing or routine GMP inspection is coming, from FDA or an EU authority, and inspectors will ask how your electronic data is controlled.
• You are replacing paper or old software. A new MES, LIMS, eQMS or cloud platform is being introduced, and validation has to be planned before go-live, not reconstructed afterwards.
• A group standard applies across sites. A parent company wants one approach to computerised systems in every plant and laboratory, whatever the local regulator.

The benefit is data you can defend. It depends on systems being run and reviewed every day, not on a validation binder filed once.

Requirements

What are the main 21 CFR Part 11 and Annex 11 requirements?

Part 11 is arranged in three subparts. Annex 11 runs in seventeen numbered sections, from risk management to archiving. The list below is a plain-language map of the parts your programme must answer; the texts themselves are checked point by point during the gap analysis, with your legal and regulatory advisers where interpretation matters.

• Part 11, Subpart A General provisions: the scope of the part and the definitions it relies on, which decide which of your records and systems are in play.
• Part 11, Subpart B Electronic records: controls for closed systems, how a signature is shown on a signed record, and the link that keeps a signature bound to its record.
• Part 11, Subpart C Electronic signatures: the requirements that apply to electronic signatures themselves.
• Annex 11, Risk management and suppliers: decisions on validation and data integrity controls driven by risk, and suppliers and service providers assessed and bound by agreement.
• Annex 11, Validation: the validation of computerised systems, with documented evidence your quality unit approves.
• Annex 11, Audit trails, change and periodic evaluation: audit trails in place and regularly reviewed; change and configuration managed; systems periodically evaluated to confirm they remain valid.
• Annex 11, Security and electronic signature: controlled access to systems and data, and the rules for electronic signatures in GMP records.
• Annex 11, Business continuity and archiving: arrangements that keep critical processes running if a system fails, and archived data that stays readable and intact.

Compliance process

How do you become 21 CFR Part 11 and Annex 11 compliant?

There is no certificate at the end. Compliance is a state your systems stay in, shown to FDA investigators, EU GMP inspectors and customer auditors whenever they ask. Sterling helps you build and run the programme; the regulator alone judges compliance.

1. 01
   Inventory the systems and records in scope.List every system that creates, changes, signs or stores GxP data, decide which records are regulated, and classify each system by its impact on product quality and data integrity.
2. 02
   Gap analysis: compare each system with both texts.Configuration, access, audit trails, signatures, supplier arrangements and existing validation files are reviewed, and actions are agreed with owners, dates and a priority set by risk.
3. 03
   Remediate, validate and train.Procedures for system life cycle, access and data review are put in place; your team plans and executes validation proportionate to risk, with Sterling beside them; users and reviewers are trained.
4. 04
   Self-inspect and close the findings.A data integrity self-inspection and a mock inspection test systems and records as an inspector would; we raise the findings first and close them on evidence.
5. 05
   Stay in a validated state.Audit trail reviews, access reviews, change control, periodic evaluations and supplier oversight continue between inspections, and the revised Annex 11 is planned for once adopted.

Check the route before you sign. A "Part 11 certificate" or an "Annex 11 certificate" is not something any regulator issues, and a vendor's statement that its software is compliant does not transfer to you: compliance depends on how you configure, validate and use the system. Ask providers what they will deliver, who approves it and which records you keep. In the EU, GMP certificates come only from national competent authorities after inspection.

Cost

How much does 21 CFR Part 11 and Annex 11 compliance cost?

A laboratory with three well-supported systems needs a fraction of the work of a multi-site manufacturer running legacy software and custom spreadsheets. Cost follows the number of systems, their risk and the state of their documentation; every component is shown, and nothing is added later.

Timeline

How long does 21 CFR Part 11 and Annex 11 compliance take?

As an estimate, three to nine months for a typical site, longer where legacy systems must be replaced. The procedures come quickly; time goes into testing, vendor changes and running reviews long enough to show they happen.

If an inspection or a customer audit is booked, tell us at the first meeting. We will say plainly what can be ready and which systems to tackle first.
