Electronic Signatures and Approvals in Quality Workflows

What Every Approval Has to Prove Later

An approval is only as good as the evidence behind it. Months later, an auditor or a customer will pick one NCR or CAPA and ask four questions. If the record answers all four on its own, the approval stands. If someone has to explain it from memory, it does not. Review your current sign-off records with our compliance team.

Six Clauses Behind Every Electronic Signature

For FDA-regulated records, 21 CFR Part 11 sets the rules. FDA's August 2003 Scope and Application guidance narrowed how Part 11 is applied and eased enforcement in areas such as validation and audit trails, but it stated that the signature sections, 11.50, 11.70, 11.100, 11.200 and 11.300, would still be enforced. Walk through each clause on a live record in a Part 11 walkthrough.

Author, Reviewer, Approver: Say What Each Signature Means

Part 11 lists review, approval, responsibility and authorship as examples of signature meaning. A signature without a stated meaning leaves an auditor guessing whether the person checked the work or simply saw it. Fix the meanings in your procedures and make the system show them every time. Ask our support team for a sample signature manifest.

Segregation of Duties Built Into the Route

Part 11 requires authority checks so only authorised people can sign or change a record, and written policies that hold people accountable for actions under their signatures. Segregation of duties takes this one step further: the person who raises a nonconformance should not be the one who approves its disposition. Map your roles in a role design session.

Route Each Approval by Its Risk Level

Not every record needs three signatures. ICH Q9(R1) sets the principle that effort, formality and documentation should match the level of risk, and the same logic works for approval workflows. These routes are illustrations, not a standard. Your own procedures and customer requirements set the final rules. Plan your risk tiers with our quality specialists.

One Session, Many Signatures: When to Ask Again

Section 11.200 handles a common situation: a QA manager signing several records in one sitting. The first signing in a continuous session uses all signature components. Later signings in the same session need at least one component that only that person can use. A new session starts the full check again. See the signing steps on screen in a sign-off demo.

What the Audit Trail Shows Around One Approval

The signature tells you the decision. The audit trail tells you how the record got there: who changed what, when, and the reason they gave. Earlier values stay visible, and the trail is kept as long as the record itself. The example is illustrative. Ask our support team for a sample audit export.

EU GMP, IATF 16949, ISO 9001 and AS9100

Traceable approvals are not only a pharma concern. EU GMP has its own rule, and in automotive, aerospace and general manufacturing it is usually the customer's auditor who asks to see who approved a release or a concession. One set of signature controls can serve all of them. Compare your audit requirements in a compliance review call.

An Approval Route Template for Each Record Type

Write one route per record type before go-live. It turns your procedures into rules the system can enforce and gives auditors one place to see who may sign what. Ask our compliance team for a blank version.

Size the Time Spent Chasing Signatures

The main value of signature controls is an approval that holds up in an audit, which is hard to price and should not be inflated. The part you can size is the time spent carrying paper between desks and chasing signers. The figures below are assumed inputs that show the arithmetic only. Build your own case in a sizing session.

Add faster audit preparation and fewer findings on missing signatures only where your own records support a figure.

Implementation Guide: Signature Controls on Your Own Server

iFactory delivers Signature Controls as a turnkey package. A pre-configured NVIDIA AI server ships racked and ready, so records, signatures and audit trails stay on your site, and the AI can flag stalled approvals and route records locally. You rack it, plug in power and Ethernet, and the AI is live. Scope the rollout with our implementation team.

Approvals Your Auditors Can Follow

iFactory builds signature controls into the quality workflow itself, so the right approval is also the easiest one. See it on your own records in a signature controls demo.
