GoKawiilNew framework names 'Change Coupling' as hidden driver of code complexity
A software engineering piece describes 'Change Coupling,' a pattern where files that appear unrelated in code still must be edited together, forcing small fixes to ripple across many files. The author distinguishes this from physical, logical and temporal coupling, arguing static analysis alone cannot detect it and developers must build intuition over time working in a codebase.
GoKawiil's interpretation of the reporting above, not reported fact.
The framing positions Change Coupling as a diagnostic lens rather than a metric to minimize, which could shift how teams evaluate technical debt and review processes. By arguing hidden dependencies exist independent of code structure, the author suggests teams may need new practices—such as tracking co-change history—to reduce cognitive load during edits.
- Change Coupling describes files that must change together despite no direct code reference
- It's presented as a sense-making tool, not a metric to optimize
- Static analysis reportedly can't detect it, requiring experience-based intuition
