21 CFR Part 11 Compliant Software for FDA-Regulated Maintenance
In pharma, food, and medical device plants, your maintenance records are FDA records too — and Part 11 sets the bar for how electronic records and signatures must be controlled.
What Is 21 CFR Part 11 Software?
21 CFR Part 11 software is software built to meet the FDA regulation (21 CFR Part 11) that defines when electronic records and electronic signatures are considered trustworthy, reliable, and equivalent to paper records and handwritten signatures. The rule applies to companies in FDA-regulated industries — pharmaceutical manufacturing, food and beverage, medical devices, and biotech — that create, modify, maintain, or transmit records electronically under FDA predicate rules such as GMP.
In plain terms: if your maintenance operation logs equipment calibrations, preventive maintenance, or repairs in software rather than on paper, that software needs to be 21 CFR Part 11 software to protect those records. It exists so an auditor can trust that a digital record is complete, attributable, and hasn’t been altered without a trace. The FDA’s own guidance on scope and application is available directly from the FDA’s guidance library.
What does Part 11 require?
Part 11 requires that electronic records stay accurate, attributable, and tamper-evident, and that electronic signatures are uniquely tied to the person who applied them. Those principles translate into a handful of concrete system controls:
- Audit trails — secure, computer-generated, time-stamped records of who did what and when, capturing creation, changes, and deletions without overwriting prior entries.
- Electronic signatures — signatures bound to their records, showing the signer’s name, the date and time, and the meaning of the signing (approval, review, responsibility).
- Access controls — limiting system access to authorized individuals, with role-based permissions so people can only reach the functions their job requires.
- Record integrity and retrieval — the ability to generate accurate, complete copies of records for inspection throughout the required retention period.
- Operational and authority checks — enforcing permitted sequences of steps and verifying that only authorized users perform signings or critical actions.
Part 11 compliance is a shared responsibility. The software must provide the technical controls; your organization owns the procedures, validation, and training that put those controls to use.
Why regulated maintenance needs it
Maintenance records carry regulatory weight because equipment condition directly affects product quality and patient safety. When a chromatography system is calibrated, a cleanroom HVAC unit is serviced, or a sterilizer is repaired, the FDA expects a defensible record proving the work happened, who performed it, and that the asset was returned to a qualified state.
Paper logs and generic spreadsheets struggle here — they can be edited without a trace, lack enforced signatures, and are slow to produce during an inspection. That’s why preventive maintenance programs in regulated plants increasingly run on systems built to protect the record itself, not just schedule the task. The same discipline that governs electrical safety work under NFPA 70B applies to FDA environments: the record has to hold up under scrutiny.
How a CMMS supports Part 11 requirements
21 CFR Part 11 software built into a CMMS supports Part 11 by enforcing the electronic-record and access controls the regulation calls for across every work order, PM, and asset history. Rather than bolting compliance onto paper, the system captures a defensible digital trail as maintenance happens. The table below maps core Part 11 requirements to the CMMS capabilities that support them.
| Part 11 requirement | How a CMMS supports it |
|---|---|
| Audit trails | Time-stamped, user-attributed history on work orders and asset records — captures who created, edited, or closed each entry without overwriting prior data. |
| Electronic signatures | Sign-off steps that tie a named user to an action (completing, approving, or reviewing a work order) with date and time recorded. |
| Access controls | Role-based permissions restrict who can view, edit, approve, or delete — so technicians, supervisors, and QA each see only what their role allows. |
| Record integrity | Centralized records that can’t be quietly altered, with complete asset management histories retained and retrievable for inspection. |
| Accurate copies for inspection | On-demand reporting and export produce complete, readable records for auditors instead of reassembling paper files. |
eWorkOrders provides these supporting controls — audit trails, granular permissions, and electronic records across the maintenance workflow — as part of our broader move toward serving validated, regulated environments. We position the platform as supporting Part 11 requirements, not as a pre-validated or FDA-certified system; validation of any computerized system remains the responsibility of the regulated organization that deploys it.

For 31 years we’ve helped maintenance teams — including operations at McDonald’s, Burger King, and ASSA ABLOY — keep assets running with 99.99% uptime and a 4.9 rating on both Capterra and G2. Let us show you how audit trails, role-based access, and electronic records fit your compliance workflow, configured to your operation in a single working session.
Frequently Asked Questions
Is eWorkOrders 21 CFR Part 11 certified?
No software is “Part 11 certified” — the FDA does not certify products. eWorkOrders supports Part 11 requirements through audit trails, access controls, and electronic records, and is moving toward serving validated, regulated environments. Validation of the deployed system remains the regulated organization’s responsibility.
What’s the difference between electronic records and electronic signatures?
An electronic record is the data itself — a work order, calibration log, or asset history. An electronic signature is the authenticated act of a named user approving or attesting to that record. Part 11 covers both and requires signatures to be linked to their records.
Do audit trails have to be automatic?
Yes. Part 11 calls for secure, computer-generated, time-stamped audit trails that record actions independently of the user. A compliant maintenance system logs creation, changes, and deletions automatically rather than relying on people to note them.
Which maintenance operations need Part 11 controls?
Any FDA-regulated facility keeping maintenance records electronically — pharmaceutical, biotech, medical device, and food and beverage plants — where equipment upkeep affects GMP-governed product quality, safety, or process control.
