How do I ensure my revision control workflow with engineering change management software is compliant?

To keep a revision control workflow compliant when using engineering change management (ECM) software, you need to make sure the workflow is controlled, traceable, approved, validated, and auditable.

Here’s a practical checklist:

1. Define a formal change process

• Document the steps for proposing, reviewing, approving, implementing, and closing changes.
• Make sure the process matches your applicable standards/regulations, such as:
  • ISO 9001
  • AS9100
  • IATF 16949
  • FDA 21 CFR Part 11 / 820
  • ISO 13485
  • internal quality procedures

2. Use controlled revision numbering

• Ensure every part, drawing, document, and BOM has a unique revision history.
• Prevent uncontrolled edits or overwrites.
• Keep the current approved revision clearly identified.

3. Enforce approvals before release

• Require authorized reviewers/approvers for every change.
• Use role-based access so only approved users can release or modify controlled records.
• Separate drafting, review, and approval responsibilities where needed.

4. Maintain full traceability

• Record:
  • who requested the change
  • why it was needed
  • what was changed
  • who reviewed and approved it
  • when it was released
• Link change requests to affected items, test results, deviations, and downstream documents.

5. Preserve audit trails

• Use software that automatically logs:
  • edits
  • status changes
  • approvals
  • timestamps
  • user identities
• Make sure audit logs are tamper-resistant and retained per your retention policy.

6. Validate the software

• If the ECM system supports regulated records, validate it for its intended use.
• Document that it works as intended for:
  • access control
  • version control
  • approvals
  • record retention
  • electronic signatures
• Revalidate after major upgrades or configuration changes.

7. Control electronic signatures and access

• If electronic signatures are used, ensure they meet regulatory requirements.
• Require unique user IDs and strong authentication.
• Restrict permissions based on job role and need-to-know.

8. Verify implementation and effective date

• Ensure the released revision is the one actually used in production, service, purchasing, and quality systems.
• Define effective dates and cutover rules for obsolete vs. active revisions.

9. Train users

• Train engineers, reviewers, approvers, and operators on:
  • change control rules
  • how to use the ECM system
  • compliance responsibilities
• Keep training records.

10. Audit and improve

• Perform periodic internal audits of change records and revision workflows.
• Check for:
  • missing approvals
  • undocumented changes
  • incorrect revision usage
  • overdue closures
  • incomplete traceability
• Correct gaps with CAPA if needed.

Common compliance pitfalls

• Making changes outside the system
• Approving changes after implementation without justification
• Missing audit trails
• Poorly defined approval authority
• Not validating the software
• Using outdated revisions in production

Best practice

Create a standard operating procedure (SOP) for change control and configure your ECM software to enforce it automatically as much as possible.
