coupling-cohesion

You can analyze code structure to diagnose structural decay by evaluating code relationships to identify high coupling and low cohesion, which directly impacts maintainability and readability.

High coupling and low cohesion occur when code relationships are tightly intertwined and poorly grouped, causing structural decay where changes in one part trigger unintended side effects in others.

Refactoring a difficult-to-test module requires assessing its coupling and cohesion levels to improve the design hierarchy, which isolates changes and prevents unintended side effects across the codebase.

You need coupling and cohesion analysis when new features require extensive modifications in multiple places, or when module dependencies cause changes in one part of the code to have unintended side effects.

Yes, you can assess code relationships and advise on improving the design hierarchy of coupling and cohesion levels directly within your codebase directory without requiring external dependencies.

The best way to improve maintainability and readability is to diagnose structural decay by analyzing coupling and cohesion levels, then applying targeted refactoring recommendations to optimize code relationships.
