Write four lines for each thing you report:
- The result. What changed because of your work.
- The proof. A document, a figure or a person who can confirm it.
- The limit. What it does not show.
- What comes next.
Example
Result: I rebuilt the pricing model, and sales has used it for every quote since January. Proof: the sales lead's email of 14 January, and the quote log. Limit: there is no margin comparison with last year yet. Next: report margins after the second quarter.
