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 1 is aimed at business analysts, solution architects, designers and developers. It provides them with a formal method to develop agile, cost-effective and low-risk solutions to meet business requirements - the goals of SOA.
