Assume

Does each class or module have only one job? For example, an email module should only handle sending emails, not deciding who gets them.

Do high-level modules depend on abstractions rather than low-level details? This keeps components isolated and easier to test. 2. Reviewing the "Assume" Factor assume

Are interfaces small and specific? Clients shouldn't be forced to depend on methods they don't use. Does each class or module have only one job

In software engineering, a refers to checking code against five key principles to ensure it is maintainable and scalable. This keeps components isolated and easier to test

If you are looking to review assumptions—whether in research, design, or personal life—a "solid" approach involves moving from guesswork to evidence.

Can a subclass replace its parent class without breaking the program? If is a subtype of , you should be able to use is expected.

When you hear "SOLID," you might be thinking of the gold standard for software design, or perhaps you're looking for a "solid" way to review the assumptions we make in everyday life. Since your request is a bit open-ended, 1. The Technical "SOLID" Review
