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

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

SOA Governance

Governance widely recognized as crucial for 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
