Why is it principled to adhere to SOLID principles when developing software?

The SOLID principle helps create flexible, maintainable, and extendable code. Following it reduces the likelihood of errors and simplifies testing.

Briefly about each principle:

• S (Single Responsibility Principle) — a class should have one responsibility.
• O (Open/Closed Principle) — software entities should be open for extension but closed for modification.
• L (Liskov Substitution Principle) — objects of subclasses should replace objects of base classes without affecting correctness.
• I (Interface Segregation Principle) — it's better to have several specific interfaces than one universal interface.
• D (Dependency Inversion Principle) — dependencies should be based on abstractions, not on concrete implementations.

Adhering to SOLID allows the team to make changes faster and scale the project more easily.
