The SOA Working Group
The mission of The Open Group SOA Working Group is to develop and foster common understanding of Service-Oriented Architecture in order to facilitate alignment between the business and information technology communities.
It does this by conducting a work program which will produce definitions, analyses, recommendations, reference models, and standards to assist business and information technology professionals within and outside of the Open Group to understand and adopt SOA.

How the Work Program Develops
Any Working Group member can propose a project
A proposed project must Be within the Working Group’s scope Be achievable with Working Group resources
Project proposals are approved by vote of the Working Group
Several project proposals have been approved and others are being developed, based on “Value” team recommendations

Definition of SOA
An architectural style that supports service orientation Service orientation
A way of thinking in terms of services and service based development and the outcomes that services bring
ServiceA logical representation of a repeatable business activity that has a specified outcome (e.g., check customer credit; provide weather data, consolidate drilling reports), is self-contained and may be composed of other Services. It is a black box to consumers of the Service
Architectural StyleThe combination of distinctive features in which Enterprise Architecture is done, or expressed
The SOA Architectural style’s distinctive features: Based on the design of the services comprising an enterprise’s (or inter-enterprise) business
processes. Services mirror real-world business activity Service representation utilizes business descriptions. Service representation requires
providing its context (including business process, goal, rule, policy, service interface and service component) and service orchestration to implement service
Has unique requirements on infrastructure. Implementations are recommended to use open standards, realize interoperability and location transparency.
Implementations are environment specific, they are constrained or enabled by context and must be described within their context.
Requires strong governance of service representation and implementation Requires a “Litmus Test", which determined a “good services”
