What is a software product line l.jpg
What is a Software Product Line?

A software product line is a set of software-intensive systems sharing a common, managed set of futures that satisfy the specific needs of a particular market segment or mission and that are developed from a common set of core assets in a prescribed way.

  • Traditional Software Reuse

    • reuse library with components, modules and algorihtms

    • takes longer to find the desired functionality

  • SPL

    • reuse is planned, enabled and enforced
