phuryn/pre-mortem

對產品需求文件(PRD)或發布計畫執行預先檢討風險分析,將風險分類為老虎(真實問題)、紙老虎(被誇大的擔憂)與大象(未說出口的憂慮),並區分為阻礙發布、快速跟進或持續追蹤。適用於準備發布、壓力測試產品計畫或找出可能出錯之處。

pre-mortem 是什麼?

這項技能能幫助開發者與產品經理在發布前進行系統化的風險預測分析。它會將風險分為三大類:Tigers(真實且需立即解決的問題)、Paper Tigers(表面嚴重但實際上影響有限的問題)以及Elephants團隊未明說但可能潛在的巨大隱憂。分析完成後會進一步根據嚴重性將風險分級為Launch-blocking(必須在發布前解決)、Fast-follow(發布後立即處理)或Track(長期監控)。此技能支援任何可執行AI代理的平台如Claude Code或Cursor,用戶只需提供PRD或發布計畫文字,AI便會自動生成風險矩陣與行動建議。

pre-mortem 是做什麼的?

對產品需求文件(PRD)或發布計畫執行預先檢討風險分析。將風險分類為老虎(真實問題)、紙老虎(被誇大的擔憂)與大象(未說出口的憂慮),然後區分為阻礙發布、快速跟進或持續追蹤。適用於準備發布、壓力測試產品計畫或找出可能出錯之處。

如何使用

  1. 提供你的 PRD 或發布計畫文字內容(例如貼入文件或摘要)。
  2. AI 代理會辨識並分類每項風險:
    • 老虎 🐯:高影響、高確定性的實際問題,需立即處理。
    • 紙老虎 🐆:表面嚇人但實際上影響有限的擔憂。
    • 大象 🐘:團隊未討論但潛在影響巨大的隱憂。
  3. 每項風險會進一步被標記為:
    • 🚫 launch-blocking:發布前必須解決。
    • ⚡ fast-follow:發布後立即處理。
    • 📋 track:持續監控。

範例

輸入:"我們計畫在兩週後發布新功能「智慧推薦」,但目前推薦演算法僅完成 80%,且未進行 A/B 測試。"

輸出:

  • 🐯 老虎:演算法未完成且無 A/B 測試 → 🚫 launch-blocking
  • 🐆 紙老虎:擔心用戶不理解推薦邏輯(但已有引導教學) → 📋 track
  • 🐘 大象:團隊未說出口的壓力來自時間緊湊,可能導致品質妥協 → ⚡ fast-follow

適用場景

  • 產品發布前的壓力測試。
  • 季度或年度路線圖審查。
  • 重大功能上線前的風險評估會議。

注意事項

  • 提供的文件或計畫應包含足夠的細節(至少包含目標、時間線、資源與假設)。
  • AI 分析僅供參考,最終決策仍需由團隊判斷。
