Benefits of Object-Oriented Analysis and Design (OOAD) Reusability of Components – Objects and classes can be reused across projects. Improved Maintainability – Encapsulation allows easier updates without affecting other parts. Better Mapping to Real-World Systems – Intuitive design based on real entities. Modularity – Self-contained objects simplify development and debugging. Enhanced Scalability – Easy to extend with new features. Encapsulation for Security – Data hiding improves integrity. Easier Communication – UML improves collaboration among stakeholders. Support for Concurrent Development – Teams can work in parallel on different components.
