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 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.
