Give each SOP a stable identity and an explicit approved version. Keep the current operating copy easy to find while preserving earlier versions and their effective dates. Editing history helps recover content; it does not by itself show which revision was approved for use.

The example shows the information to record; it is not an approved procedure for your business. Use actual identifiers, decisions and dates.

For a continuously maintained document, a stable name such as OPS-004 Office intake can reduce unnecessary link changes. Put the released version and effective date inside it and in the register. A filename does not prove approval, and stable naming cannot prevent broken permissions or deleted files.

For an immutable export, a versioned name such as OPS-004_v2.1_2026-11-04.pdf helps distinguish snapshots. Printed and exported pages should identify the procedure and version so they can be checked against the current register.

Separate drafting from publishing

Define who may propose edits, review them and release the operating version. In SharePoint, versioning, content approval and draft visibility have distinct settings; check-out also affects collaboration. Verify the configured behavior rather than assuming that saved edits are hidden from readers. Versioning guidance.

When a revision is approved, record the change and effective date, update the index, notify affected users and withdraw obsolete operating copies. Decide explicitly how already-open work is handled.

Preserve history and test recovery

Retain the historical revisions and execution records needed by the organization. Do not delete old versions solely because the active folder looks crowded. Restrict or label them so readers do not confuse history with current instructions.

Test that an authorized person can retrieve the required version and identify when it applied. A successful restore also needs a review of access and release status; restoring text does not automatically authorize it for current use.

Choose a consistent numbering convention. A major/minor scheme can be useful if its meaning is documented, but there is no universal rule that three revisions in a month require a rewrite.

Use the SOP register for current-version lookup and the maintenance log for review decisions. The maintenance guide distinguishes reviewed, revised and effective dates.
