What is Extendibility in Software Development?

Extendibility refers to the ability of a system or software to be modified or expanded to meet new requirements or to adapt to changing circumstances. It is the capacity to add new features, functionality, or components to an existing system without disrupting its core functionality.

In software development, extendibility is often achieved through the use of modular design, where different components of the software are designed to be independent and interoperable, allowing for easy integration of new modules or features as needed. Other techniques for achieving extendibility include using open APIs, designing for scalability, and using modular architectures.

Extendibility is important because it allows organizations to adapt their systems and software to changing business needs over time, without having to completely replace existing systems. This can save time, money, and resources, and can help organizations stay competitive in a rapidly changing marketplace.
