What does it mean that output versioning?

Track versions of important outputs so you can compare and revert if needed.

Example: You shipped a strategy memo on Monday, received feedback Tuesday, and revised it Wednesday — but because you saved each version with a clear label, you could compare all three side by side and prove to your skeptical VP that the revision actually addressed every objection, rather than scrambling to remember what changed.

Try this: Pick one important output you produced in the last month. Reconstruct its version history — how many distinct drafts or revisions existed? Can you access earlier versions? If not, establish a versioning protocol for that output type today: name the convention, choose the storage location, and save the current version as v1.0 with a one-line changelog entry describing its state.
