Software product line engineering

Software product line (SPL) is being used as a software development paradigms for increasing the productivity of IT related industries. Product line engineering has been developed to build product variants using product line assets including common architectures and components. These architectures and components are built with variation points based on the commonalities and variabilities of the products in the application domain. The ultimate goal of product line engineering is to improve the productivity of product development and the quality of products and services a company provides. Runtime dynamism is an emerging area of research in product line engineering and the focus of software engineering shifts, from static development-time engineering to dynamic runtime engineering. Non-technical issues as well as technical issues must be addressed to facilitate product line engineering to be adopted by the software development industry.
