To identify SOLID design violations during a code review, apply a structured checklist to spot design smells like fat interfaces, tight coupling, and improper dependency management in object-oriented systems.

The best way to refactor a Single Responsibility Principle violation is to split the bloated class into smaller, more cohesive modules. This refactoring strategy reduces technical debt and improves overall software maintainability.

Dependency Inversion improves clean code architecture by enforcing loose coupling between high-level and low-level modules through abstractions. This design principle prevents improper dependency management and reduces architectural fragility.

Yes, you can use this SOLID methodology to review existing codebases for technical debt. It provides actionable definitions for all five design principles to identify architectural fragility and suggest specific refactoring steps for complex systems.

You should apply interface segregation to fix fat interfaces when a single contract forces classes to implement methods they do not use. This refactoring strategy splits bulky interfaces into cohesive, client-specific contracts to improve maintainability.
