List 4 types of specialization of software product lines?

Ans: Various types of specialization of a software product line may be developed:

1. Platform specialization: Versions of the application are developed for different platforms. For example, versions of the application may exist for Windows, Mac OS, and Linux platforms. In this case, the functionality of the application is normally unchanged; only those components that interface with the hardware and operating system are modified.

2. Environment specialization: Versions of the application are created to handle particular operating environments and peripheral devices. For example, a system for the emergency services may exist in different versions, depending on the vehicle communications system. In this case, the system components are changed to reflect the functionality of the communications equipment used.

3. Functional specialization: Versions of the application are created for specific customers who have different requirements. For example, a library automation system may be modified depending on whether it is used in a public library, a reference library, or a university library. In this case, components that implement functionality may be modified and new components added to the system.

4. Process specialization: The system is adapted to cope with specific business processes. For example, an ordering system may be adapted to cope with a centralized ordering process in one company and a distributed process in another.
