🌏 閱讀中文版本 By: rajatim Abstract: We celebrate “agile” and “failing fast,” but we seldom talk about the cost of failure. This article explores an ongoing paradigm shift in product development: moving from “Hypothesis-Driven Development” to a “Continuously Evolving Intelligence” formed by the synergy of DevOps, PM, and AI. This is not just a process optimization; … Read more
本文探討一個產品開發的範式轉移：從被動驗證假說，演進為由 DevOps、PM 與 AI 構成的「持續進化智慧」體。文章將闡述這個新範式如何重塑技術人員的價值，並提供一個可執行的架構藍圖，將團隊從功能實現者，升級為自我進化系統的建築師。

🌏 閱讀中文版本 Have you experienced this scenario: Your product manager says “Support a new discount rule,” and suddenly you’re modifying OrderService, DiscountService, PromotionService, PricingService, and CustomerService. By the time you’re done, you realize this “simple” requirement touched 5 different modules. This isn’t an edge case. It’s a symptom of poor system design. Domain-Driven Design (DDD) … Read more
