  1. 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
  2. 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
  3. 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
