Most factories that are moving away from paper-based quality records hit the same wall. Someone asks: "Are our digital records actually compliant?" The short answer is yes, but only if your system is set up to meet a specific set of requirements. In the US, those requirements live in 21 CFR Part 11.

This article explains what the regulation covers, who it applies to, and what it actually demands from your systems and processes. It also covers what Quality and Compliance solution we’ve built into our Connected Operations app to help manufacturers operate confidently within those boundaries.

Factbird's e-signature flow uses two-factor authentication: operators select their identity and confirm with a PIN.

What 21 CFR Part 11 actually is

Title 21 of the Code of Federal Regulations, Part 11, is an FDA rule that defines the conditions under which electronic records and electronic signatures are considered trustworthy, reliable, and legally equivalent to paper records and handwritten signatures.

It was introduced in 1997, when the FDA recognized that computer systems were replacing paper in regulated environments, and that new rules were needed to govern that shift.  

The core premise is straightforward: if you want to use a digital system to do what paper and ink used to do, that system needs to meet specific technical and procedural requirements.

The regulation covers any record in electronic form that is created, modified, maintained, archived, retrieved, or transmitted under FDA recordkeeping requirements.

Who it applies to

21 CFR Part 11 is most closely associated with pharmaceutical and medical device manufacturing, but its scope is broader than most people assume.

It applies to any organization operating under FDA oversight that uses electronic systems to manage records. While pharma and medical devices are the obvious cases, food and beverage producers managing safety and traceability records fall under it too.

Regulated manufacturers, including those in food and beverage, are required to maintain traceable electronic records.

What the regulation actually requires

The requirements fall into two areas: electronic records and electronic signatures.

For electronic records:

Validation

The system must be validated to prove it does what it claims to do, consistently and accurately. This is not a one-time checkbox. It means documented evidence that your system performs reliably under real operating conditions.

Audit trails

The system must generate secure, computer-generated, time-stamped audit trails that capture who did what, and when. These trails log every action that creates, modifies, or deletes a record. Users cannot edit them after the fact.

Access controls

Only authorized individuals should be able to access the system or specific parts of it. This requires unique user accounts, clearly defined permissions, and controls that prevent unauthorized changes.

Record integrity

The system must be able to generate accurate, complete copies of records that people can read and review, not just machine-processable exports. Records must also remain protected and accessible for as long as your retention requirements demand.

For electronic signatures:

Unique identity

Each signature must be tied to a single individual. Shared logins do not satisfy this requirement.

Full attribution

Signed records must include the signer's name, the date and time, and the meaning of the signature, for example: reviewed, approved, or verified.

Permanent linking

The signature must be permanently attached to the record it belongs to and cannot be removed or reassigned afterward.

Why it matters beyond just staying compliant

Non-compliance carries real consequences. An inspection that uncovers data integrity failures can result in formal observations, warning letters, delays to product approvals, or in serious cases, legal action. Beyond the regulatory fallout, it damages the credibility of your quality program in ways that are slow to recover from.

If you operate outside the US, the underlying requirements are not unique to the FDA. EU GMP Annex 11 governs electronic records and data integrity for manufacturers operating under European regulations, and the expectations are closely aligned. The same controls that satisfy Part 11 largely satisfy Annex 11 too.

The operational argument for meeting these requirements is just as strong as the regulatory one. Audit trails, access controls, and time-stamped records are not bureaucratic overhead. They are the infrastructure of a trustworthy quality system. When you can trace every check back to the person who performed it and know the record has not been touched since, you have something genuinely useful: a clear account of what happened on the line and when.

For manufacturers dealing with tight margins and high production volumes, that traceability also speeds up root cause analysis. Instead of chasing down handwritten spreadsheets or asking operators to reconstruct what happened, teams can go directly to the digital record.

What we built to support this

Quality and Compliance solution is part of our Connected Operations app, and is built to help manufacturers move quality checks, sign-offs, and recordkeeping out of paper and into structured digital workflows that hold up to scrutiny.

Here is what that looks like in practice:

AI-assisted form conversion

Most factories already have quality forms. They are just on paper, or in a PDF that someone printed years ago. The AI Activity Creator lets you upload those existing forms directly, whether that is a paper checklist, a scanned record, or an Excel printout, and converts them into structured digital workflows that operators can follow step by step on the shop floor. You don't have to rebuild your quality processes from scratch. Digitize what already works.

Built-in e-signatures

Operators and supervisors can sign off on records directly in the system. Each signature is tied to a unique user account, time-stamped, and permanently linked to the record it belongs to. That means there is always a clear answer to who signed what, and when, and that record cannot be altered or reassigned after the fact.

Audit trails

Every action in a quality workflow is logged automatically: who completed a check, when it was done, and whether anything was modified afterward. Nothing requires manual documentation. What gets logged, stays logged.

Access controls

Not everyone on the floor should be able to complete every task, and a quality system that lets anyone sign off on anything is not really a quality system. Connected Operations uses role-based permissions to make sure the right checks are completed and signed by the right people, with a clear record of who did what across every shift.

Traceability across operators, shifts, and batches

Quality records are linked to production context, so teams can follow an issue back to its source without having to dig through paper logs or rely on operator recall. When a defect surfaces or an auditor asks what happened during a specific batch, the answer is already in the system.

Taking advantage of our Connected Operations app means that your quality checks, operator tasks, and maintenance work all live in one place rather than across separate, disconnected tools.

A note on scope

21 CFR Part 11 compliance depends on both the technology and how it is implemented. A validated system used incorrectly, with shared logins or skipped sign-offs, will not satisfy the regulation. Our Connected Operations app provides the technical infrastructure to support compliant workflows, but the procedural side, training, standard operating procedures, and internal governance, remains the responsibility of the organization using it.

If you are operating in a regulated environment and working toward full Part 11 compliance, it is worth involving your quality and regulatory teams early. We can also advise on how to configure workflows to align with your specific requirements.

A foundation for AI, not just compliance

Digitizing quality workflows does more than satisfy a regulatory requirement. When operators capture data as part of guided tasks, every input becomes structured, time-stamped, and tied to production context. For manufacturers who want to use AI to get ahead, that kind of dataset is not optional.

Every AI tool, regardless of vendor or use case, is dependent on the quality of the data it runs on. Inconsistent records, manual entries, and paper-based processes put a ceiling on what any AI feature can do. Getting your documentation right removes that ceiling.

Getting started

If your factory is still running quality checks on paper, or using a digital system that was not built with these requirements in mind, it’s worth looking at the gap on your own terms rather than waiting for an audit to find it.
