Adopting a product line paradigm creates an organizational shift. Managing product line evolution is the most DIFFICULT part of the paradigm. The product line will change as new versions of the current product come out. An organization would need to use the new versions to satisfy changing client needs. Additionally, new IMPROVEMENTS to various components may change the way the products are built. New version of components may not be entirely backward COMPATIBLE, thus additional rework will need to be done to ACCOMMODATE the changes.
