Abstract
As computer technologies evolve, it becomes a necessity for companies to upgrade their information systems. The objective of reengineering is to protect their huge investments and to maintain their competitive edge. However, information systems reengineering is a complicated task that requires much expertise and knowledge. It needs users’ input to recover lost semantics inside the existing database system and/or the existing expert system. It also requires technical expertise to replace the obsolete information systems with newer systems. Very often, due to lack of methodologies and expertise, companies choose to redevelop rather than reengineer when upgrading their information systems. The purpose of this book is to convince these companies that reengineering is a more cost-effective and feasible solution.
