DDD、SDD、TDD：三個維度的邊際效益矩陣
軟體團隊常把 DDD、SDD 與 TDD 當成三選一的方法論，但它們其實分別處理領域語言、介面契約與重構風險。本文用三軸矩陣拆解三者在不同複雜度、協作邊界與變更成本下的邊際效益，提供判斷何時投資建模、規格或測試的實用框架，避免把方法論討論變成宗教戰爭。

DDD, SDD, TDD: A Three-Axis Marginal Return Matrix
DDD, SDD, and TDD address different risks: domain language, interface contracts, and change safety. This matrix shows where each method pays off.
Why I Let AI Write Tests, But Never Let It Decide What to Test
AI wrote 200 tests for me. All passed. We deployed. Then a bug hit production. The problem wasn’t that AI wrote bad tests—it tested the wrong things. This article shares a simple framework: What stays with humans, How goes to AI.
為什麼我讓 AI 寫測試，但不讓它決定測什麼
AI 幫我寫了 200 個測試，全部通過，上線還是出 bug。問題不是 AI 寫錯，是它測的東西根本不是該測的。這篇文章分享一個簡單的框架：What 留給人，How 交給 AI。
AI Won’t Replace QA, But It Will Replace QAs Who Only Execute
AI excels at executing tests, but struggles with judging ‘what to test’ and ‘whether results are correct.’ QA’s core value is shifting from execution to acceptance—validating AI’s validation. This article analyzes the four most important QA skills in the AI era and the short, medium, and long-term impacts on teams.
AI 不會取代 QA，但會淘汰「只會執行」的 QA
AI 擅長執行測試，但不擅長判斷「該測什麼」和「結果對不對」。QA 的核心價值正在從執行轉向驗收——驗證 AI 的驗證。本文分析 AI 時代 QA 最重要的四種能力排序，以及對團隊的短中長期影響。
