ABSTRACT
Chapter Summary In this chapter, we show a more complete picture of the software evolution life cycle, including analysis, design of an x-framework, and its use during software evolution. We sketch a mixed-strategy evolution support environment (MESE). We describe techniques for organizing x-frameworks for large systems, and illustrate a process of deriving new system releases by x-framework customization in more detail. We extend our working example of a facility reservation system (FRS) to describe these more advanced concepts.
