What is Driving Business Today?
The Changing Business Landscape in the Globally Integrated Economy
Early findings from the IBM Global CEO Study to be published Spring 2008
2
Globally Integrated Economy Needs the Power of….
… service orientation
… a service
A way of integrating your
business as linked
services
and the outcomes that
they bring
A repeatable
business task – e.g.,
check customer credit;
open new account
… service oriented architecture (SOA)
An IT architectural style that supports
service orientation
But haphazard SOA deployments can reduce value

Leverage SOA Experience and Best Practices
The SOA Entry Points
 When selecting SOA projects, focus on solving specific business problems as part
of an evolving enterprise architecture
 IBM has a variety of assets and best practices around the SOA entry points, based on
our extensive experience with customers
People Entry Point:
Interaction and Collaboration
Process Entry Point:
Process Automation
Information Entry Point:
Information as a Service
Connectivity Entry Point:
Securely and flexibly interconnecting
6
Reuse Entry Point:
Creating and reusing
proven, high-value assets
Process Integrity Takes SOA to the Next Level
Enabling Integrity of Transactions, Interactions and Information

Advanced: Process Integrity
Enabling Integrity of Transactions, Interactions and Information
Process Integrity is the ability to conduct reliable business activity in a secure,
scalable SOA environment with seamless synchronization between:
Services n Human Tasks n Information n Domains n Users
Transactions Must
Execute Consistently
with Ability to Recover
as Required
Users Must Be Provided
with Up-to-date, Secure
Access to Information and
Content
Information Must be Reliable,
Complete and Manageable

Service Oriented Modeling and Architecture (SOMA)
Links Business Intent with IT Implementation
<< Input from Business Analysis >>
SOMA
Service Identification
Service Specification
Service Realization
<<Output to SOA Implementation >>
17
 SOMA gets inputs from business analysis
activities, and produces outputs necessary
for SOA implementation
 The analysis and modeling performed
during SOMA is technology and product
agnostic, but establishes a context for
making technology and product specific
decisions in later phases of the lifecycle
Service Exposure Decisions Within Service Identification
 Business Alignment:
Candidate Services
- Is the service business relevant?
- Is funding available for service development and management?
- Is the service sharable?
 Composability
-
Is the service consistent with NFRs at the composite level?
Is service stateless?
Is the service self-contained? (Are there dependencies?)
Is the service technology neutral?
Business Alignment
Composability
Externalized Service Description
 Externalized Service Description
- Is there an externalized service description e.g. WSDL?
- Can the service be discovered and bound via the service description?
- Does the description contain meta-data about itself?
Redundancy Elimination
Service Litmus
Test
 Redundancy Elimination
- Can the service be applied to all processes where its function is
required?
