Boundaryless Information Flow
Enterprise IT should make information available Where it is needed When it is needed
To support the business operation of the boundaryless organization
April 13, 2023 (C) The Open Group 20069
Achieving Boundaryless Information Flow
Boundaryless information flow is implemented through enterprise IT architecture
It needs open standards to enable Interchangeable and
interoperable products Interworking between
enterprises

Service Oriented Architecture
SOA is an architectural style That re-structures applications as loosely-
coupled, modular services To deliver Boundaryless Information Flow

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.
April 13, 2023 (C) The Open Group 200614
SOA WG Membership
Open to all Open Group Supplier and Customer Council members (platinum members, forum buyout members, and silver members)
149 participants from 50 companies

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”

Value that The Open Group can Add
The main goal of the subgroup was to establish a set of areas which the Open Group could benefit the industry in the context of SOA.
There were 10 recommendations selected. Definition of SOA (existing project) SOA Case Studies (existing project) SOA Maturity Model SOA Reference Model SOA Relation to EA (TOGAF) Business-Driven SOA Legacy Evolution to SOA SOA Governance Ontologies for SOA SOA Key Performance Indicators

Ontologies for SOA
Objectives: Improve Understanding Basis for Model-Driven Implementation
Current State Draft base ontology developed Refined following workshop in Lisbon
To be presented to OMG joint SOA ABSIG, Ontology PSIG and Healthcare DTF at 13:00 on December 5

SOA Governance
Governance widely recognized as crucial for SOA
Project team currently Establishing scope Reviewing inputs – members and SOA
Alliance Will meet face-to-face in San Diego in
January to start substantive drafting

SOA/TOGAF Practical Guide
Relation of SOA to EA/TOGAF perceived as highest value the WG can add for SOA
Joint project of SOA WG and Architecture Forum
Working through steps of TOGAF Architecture Development Method to evaluate impact of SOA

In Conclusion
SOA is important to The Open Group because The Open Group exists to drive the creation of boundaryless
information flow through enterprise architecture SOA is the style of enterprise architecture that enables
boundaryless information flow The Open Group is working on
