Rolling Forecast Version Delta Review

Compare two versions of a rolling forecast line by line and record who changed each assumption and why.

What to provide

Current and prior rolling forecast versions, the assumption log, the owner roster and the change policy.

Workflow

1. Align both versions on the same periods and units before comparing.
2. List every changed line with old value, new value and absolute delta.
3. Match each change to an assumption log entry and owner; flag undocumented changes.
4. Return the delta register without overwriting either version.

Output contract

Line | period | old | new | delta | assumption entry | owner | undocumented | reviewer

Fictional acceptance test

Fictional v4 versus v3: 3 of 40 lines changed; two have log entries and one shows marketing spend up 8% with no entry. Flag the undocumented change only.

Review gates and limits

Re-check period alignment before flagging deltas. A shift in forecast horizon is not a line change.
