Single Responsibility Principle: Strengths and Weaknesses

Advantages

The advantages of following the Single Responsibility Principle (SRP) include the following:

• Better code organization and maintainability.
• Improved readability and understanding of code.
• Easier debugging and testing of code.
• A higher degree of code reusability.
• Facilitation of parallel development and implementation of new features.
• Ability to make changes to code with less risk of introducing bugs.

Disadvantages

Some of the disadvantages of the Single Responsibility Principle (SRP) include the following:

• Increased complexity, as a system may require more classes to implement the same functionality.
• Potential for over-engineering, leading to too much abstraction and unnecessary code.
• Difficulties in determining the appropriate granularity of responsibilities.
• Challenges in balancing the trade-off between separating responsibilities and maintaining performance.

When programmers try to add features or new behaviour to a software product, they frequently integrate everything within the current class. When something needs to be changed later, due to the complexity of the code, the code refactor process is extremely time-consuming and tedious.

The Single Responsibility Principle helps us create simple classes that perform just one task. This helps make modifications or adding extensions to the existing code much more effortless.
