Software reengineering for reusability

Programs are often reengineered for better maintainability or in order to migrate programs into newer computer/software platforms. However, many of the aging business systems must be also upgraded in order to meet strategic goals of an organization. To meet such ambitious objectives, we must fundamentally redesign programs, rather than merely restructure them for improved maintainability. When much program re-design is involved, the reengineering option becomes challenging at the technical level, expensive and risky. To increase the value of the reengineering solution, we address reusability issues in the context of reengineering. In this paper, we discuss lifecycle phases and outline a possible technical scenario for reengineering for reusability
