Executive Briefing

Options-based pyramid-structured decision packages.

Use This Skill When

• Producing executive decision packages.
• Creating board-level transformation updates.
• Summarizing initiative progress for leadership.

Workflow

1. Synthesize findings from prior phases.
2. Structure with pyramid principle (conclusion → arguments → evidence).
3. Present 2-3 options with explicit trade-offs.
4. State recommended option with rationale.
5. Include risks, mitigations, and next steps.
6. Save to files.

Deliverables

• report.md: executive briefing.
• Reuse assets/exec-briefing-template.md when producing standardized briefings.

Quality Gates

• 2-3 options presented (not a single recommendation).
• Trade-offs explicit for each option.
• Pyramid structure: conclusion → arguments → evidence.
• Risks and mitigations included.
• Document marked "DRAFT — CONFIDENTIAL".

If any gate fails: identify the issue, fix, and re-validate.

Gotchas

• 「推奨オプション1つだけ」は意思決定支援にならない。必ず2-3の選択肢を提示すること
• エグゼクティブサマリーは全セクション完成後に書くこと
• 意思決定者の時間は限られている。1ページ（A4）で核心を伝えられるようにすること

Validation Loop

1. ブリーフィングを生成
2. チェック: 2-3オプション、トレードオフ、ピラミッド構造、リスク
3. 不合格なら修正
4. ユーザー承認後のみ完了 ⏸️
