Four classic symptoms of bad software design are examined with practical examples and solutions. Rigidity (cascade of changes from tight coupling) is addressed with the Strategy Pattern and Open/Closed Principle. Fragility (unrelated breakage from changes) is solved through encapsulation and Interface Segregation. Immobility (inability to reuse code) is fixed via Clean Architecture and Dependency Inversion. Viscosity (resistance to doing things correctly) is tackled through automation and infrastructure improvements. Each symptom includes a concrete scenario and actionable solution.

Symptoms of Bad Software Design

Interesting article. First step to implement this is recognizing the bad patterns in the code which can be only understandable if someone made many mistakes before. In the world of the artificial intelligence it is difficult to learn those patterns as most people now outsource the thinking part to model.

Nice article indeed. Clear and practical examples that pop ups relatively often. Bookmarked ;)

Well-written article. I enjoyed reading it.
