Dependency-Oriented Thinking: Volume 2 – Governance and Management

by Ganesh Prasad on Aug 04, 2014

About the Book Author

Ganesh Prasad has 27 years of IT experience and has been a developer and application designer through four generations of technology - mainframes, minicomputers, client-server and the web. His experience as an architect over the last 10 years, especially in the Shared Services area, has led him to pioneer radically simpler and less expensive alternatives to traditional corporate IT strategy.

Service-Oriented Architecture (SOA) is a somewhat disappointing technology buzzword from the last decade, associated with expensive and heavyweight technology that does not provide as much of a return on investment as was hyped - or is it? Has the industry just failed to understand and exploit the power of SOA?

Ganesh Prasad, an industry veteran with over a decade's worth of SOA experience at varied organisations, has discovered the secret to unlocking SOA's wasted potential. He aims to reignite SOA practice with a fresh, lightweight yet rigorous method based on the single most important element that underlies all types of system interactions - the notion of dependencies. "Dependency-Oriented Thinking" is the book that reveals these secrets for the first time.

Volume 2 is aimed at business executives, heads of IT, enterprise architects and project managers. It provides them with a formal method to direct and manage the development of systems that deliver business agility, sustainably reduce cost and minimise operational risk - the goals of SOA.
