Chapter 15 Evaluation of the mixed - strategy approach

Mixed-strategy supports generic design and enhances software changeability. The main motivation for building a mixed-strategy solution is to exploit opportunities offered by similarity patterns. By doing this, we gain extra levels of changeability, which matters in maintenance, and genericity, which matters in reuse. From the mixed-strategy perspective, there is no difference between maintainability and reusability. Change specifications and generic design mechanisms address these two important, but difficult to achieve in practice, software engineering goals in a unified, simple yet effective way.
