🌏 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
