Product brief
A rough collection of notes must become a concise brief with a clear decision and audience.
What a strong result needed- Leads with the decision
- Preserves material constraints
- Produces directly editable copy
Executive update
A long status log must become a short update that separates progress, risk, and next action.
What a strong result needed- Removes process noise
- Keeps the material blocker explicit
- Uses audience-appropriate language
Precision edit
A draft is energetic but repetitive, overclaims evidence, and hides its main point.
What a strong result needed- Removes unsupported claims
- Makes the main point easy to find
- Preserves the intended voice
