This book investigates the strategic shift from large-scale mainframe computing to smaller, distributed systems to achieve greater operational efficiency and cost reduction. Richard H. Baker, an experienced professional in information systems, utilizes historical industry trends and technical case studies to argue that downsizing is a necessary evolution for modern enterprises. He provides a framework for evaluating hardware transitions, software migration, and the organizational restructuring required to maintain productivity during a system overhaul.

Experts recognize this work as a foundational text for understanding the transition period in corporate computing history. Readers frequently note the technical density of the prose, which serves as a practical manual for IT managers navigating legacy system replacement.
