Modularity

Modularity refers to designing systems or components in separate, interchangeable parts called modules. Each module performs a specific function and can be developed, tested, and maintained independently. This approach allows for easier updates, customization, and troubleshooting since changes in one module usually don’t affect others. Think of it like building with Lego blocks: you can change or replace a single block without rebuilding the entire structure. Modularity is used in software, engineering, and organizational design to improve flexibility, scalability, and efficiency.
