How can the number of repeated components be reduced in system development?

To reduce the number of repeated components in system development, the following approaches can be used:

• Modularity and code reuse: design components to be as universal as possible and usable in different places.

• Use of design patterns: for example, patterns like "Component", "Decorator", "Factory" help create flexible and extendable components.

• Separation of concerns: each component should have a clearly defined task, which facilitates its reuse.

• Use of libraries and frameworks: apply ready-made solutions that are already tested and optimized.

• Documentation and standardization: so developers understand what components exist and how to use them, avoiding duplication.

• Refactoring and code review: regularly analyze the codebase and remove or merge similar components.

Example: in Android, reusable UI components (such as custom Views or fragments) can be created and then used across different screens instead of copying and pasting code.
