Successful Evolution of Software Systems

In today's fast-changing, competitive environment, having an up-to-date information system (IS) is critical for all companies and institutions. Rather than creating a new system from scratch, reengineering is an economical way to develop an IS to match changing business needs. Written for professionals working with medium or large information systems, this text outlines the processes involved in reverse engineering and reengineering of older systems. It helps practitioners reengineer a system to continue to provide for business critical missions as well as achieve a smooth transformation to an up-to-date software technology environment. It also demonstrates how to redevelop a flexible system that can evolve to meet future business objectives, and reduce start time and save money in the reengineering process.
