  22. 22. In summary  Software product lines epitomize the concept of strategic, planned reuse.  The product line concept is about more than a new technology. It is a new way of doing one’s software business.  There are essential product line activities and practices areas.
  23. 23. At the heart of sucessful SPLs  A pressing need that addresses the heart of the business  Long and deep domain experience  A legacy base from which to build  Architectural excellence  Process discipline  Management commitment  Loyalty to the product line as a single entity
  24. 24. Entry Criteria for SPL  Are there multiple systems with sufficient commonality?  Does the organization have articulated goals it is trying to achieve with a software product line approach?  Do the benefits of successful product lines match the goals of the organization?  Is there sufficient support within the organization to launch a software product line adoption effort?
