Designing Code for Change

Mon, 15 Jun 2026 00:00:00 +0000

Software changes. This is not a contingency — it’s the nature of software development. Requirements evolve. Systems scale. Technologies improve. Teams change. The useful question is not “will this change?” but “when it changes, how expensive will the change be?”

Code that’s designed for change is not over-engineered. It’s code where the natural boundaries of the design align with the natural boundaries of change. When a change is required, it affects a small, predictable, well-bounded area. When it’s not, the design hasn’t added unnecessary complexity “just in case.”
