SOP Version Control: Review Cycles, Change Logs, and Archiving

Good SOP version control means one source of truth, controlled versions, visible change history, defined review dates, and a clear archive path for retired procedures.

The Minimum Standard

  1. Unique document ID
  2. Version number
  3. Named owner and approver
  4. Effective date and last reviewed date
  5. Short change log
  6. Archive of superseded versions

Review Frequency

  • Annual minimum: stable, low-change work
  • Quarterly: high-change systems or higher-risk procedures
  • Immediate off-cycle: after incidents, audit findings, or system changes

Preventing Stale Copies

  • Train teams against the controlled source, not emailed attachments
  • Mark exported PDFs as uncontrolled copy
  • Archive old SOPs with clear superseded-by references

Archive, Do Not Delete

Auditors request historical evidence. Incident investigations trace back to which version was active when a failure occurred. Regulatory retention may mandate keeping records after retirement.
