The document outlines the principles of Service-Oriented Architecture (SOA), detailing the key aspects necessary for its design and implementation, including the 6 W’s (who, what, where, when, how, why). It highlights the benefits of SOA, such as cost reduction, increased agility, competitive advantage, and alignment within organizations. Additionally, it lists 8 foundational principles for SOA, including standardization, loose coupling, reusability, and discoverability.

Editor's Notes
- #3: My name is Douwe Pieter van den Bos. I’m the Thoughtleader Oracle Service-Oriented Architecture at Capgemini The Netherlands. Since 2010 I’m an Oracle ACE. I’m a published author at Packt Publishing and have presented at various international conferences, like Oracle OpenWorld.
- #5: There are,like in every design, 6 questionsthat we need to askourselves.
- #14: This model shows us the service layers as the SOA ReferenceArchitecture, courtesy of The Open Group, desrcibes.
- #15: A SOA isn’tachieved withoutstrugle, and notwithin a short amount of time. It’s a model anorganizationneeds to growinto, the complete organizationneeds to mature. The Open Group SOA Maturity Model describeswhere the maturity is found and howitcanbeachieved.The onlyway to “go-SOA” is by “Baby steps”
