An executive brief is a high-stakes communication where more is worse. Claude drafts the structure and the language. You validate the recommendation and the facts.
A well-structured executive brief answers five questions in order: What is the situation? What is the decision or action needed? What are the options? What is the recommendation and why? What is needed from the executive right now?
For investment decisions: Add a financial summary section before the rationale: investment required, expected return, payback period.
For risk or crisis situations: Lead with the risk severity and timeline, then move to recommended response, then options considered.
For board-level decisions: "Now create a 3-slide version of this brief for a board presentation: one slide per: situation and recommendation, options and rationale, ask and next steps."
Time estimate: One-page executive brief: 15-20 minutes with Claude, 15-20 minutes of editing. Versus 90 minutes to 2 hours writing from scratch.
Before the brief goes out, verify: (1) The recommendation is actually what you intend to recommend. (2) Every factual claim is accurate and verifiable. (3) The ask section is specific: vague asks do not drive decisions. (4) The tone matches the relationship you have with this executive: Claude defaults to formal.
