This article explains why software requirements must be testable, traceable, and feasible—especially for AI‑generated code—by detailing the three key qualities, practical guidelines for achieving them, and the consequences of neglecting testability, observability, controllability, and traceability.
The article examines why software requirements frequently change, introduces a four‑layer software value model—from business value to UI aesthetics—and explains how this model guides product managers and engineers in handling requirement volatility, balancing flexibility, and maintaining architectural integrity.
Using a vivid restaurant analogy, the article illustrates how original requirements, mid‑project changes, underestimated costs, indecisive features, and client pressure can lead to extensive rework, schedule delays, and chaotic development, highlighting essential product management strategies to handle evolving demands effectively.
