Version history is a record of changes to material over time. It helps you recover an earlier state, explain a changed result and distinguish a correction from a new business rule. The history is most useful when meaningful changes have a short explanation.
Keep the source, the working revision and the published version distinguishable. A file's modified date alone cannot tell you whether a price changed, a typo was fixed or the document was simply copied to another folder.
A small-business example
A company updates its delivery guidance after changing courier arrangements. Someone searching a shared drive can still find the old document, whose filename does not identify it as superseded.
The team marks the effective date in the current guidance, records what changed and retains the earlier version in a clearly labelled archive. Published references point to the current guidance. When staff investigate an older order, they can still determine which instructions applied at the time.
Try this
Pick one business note that changes regularly. Add an owner, a review date and a short change record for substantive revisions. Decide how the current version is identified and how a previous version can be recovered. Test that recovery before relying on the process for an important publication.
Freshness determines when another check is due. Source of truth identifies the maintained version, while Publish with care connects approved revisions to the public copy.
