Chapter 1. The state of business integration technology 9
anywhere on the Internet, making a huge contribution toward doing business
on the Internet.
Both of these developments are beyond the scope of this redbook and are only
mentioned here to complete our overview of Enterprise Application Integration.
1.3 Integration capabilities
WebSphere is positioned as the IBM platform for integration. There are many and
varied products in the platform, but the common denominator is that they all
support integration in one way or another. To help categorize this large number
of products on the basis of their functionality, different phases of building an
integration solution were identified. The integration capabilities of a product of the
Business Integration family of products can be categorized in six activities.
Figure 1-1 Integration capabilities
The following overview helps to position the functional offerings in the Business
Integration product set and enables us to delineate their capabilities against each
other in an effort to employ the correct technology for each solution.

These six types of integration capabilities have been identified:
Model business functions and business processes
During this stage, business analysts design or redesign processes quickly
and graphically across people, partners, and applications. The modeled
process can be simulated using what-if scenarios and optimized to obtain
projected business benefits. The modeling phase also results in deployable
components, without much code writing.
The business analysts, not the IT developers, would use a powerful graphical
tool to define and describe a new business process. Using a standard library
of processes, interfaces, and business definitions, the business analyst could
draw up a new process or make changes to an existing process. The
business analyst could document the business requirements in a
straightforward manner, which could then be shared with colleagues in the
organization. If necessary, the analyst could design forms and apply standard
business objects to the forms, or create new forms that could be used
throughout the process.
The analyst could take standard business cost for the selected elements or
apply unique costs to build up a profile of the process. Using a standard test
selection, the analyst could then run a set of transactions through the process
to see what business results arise.
IBM WebSphere Business Integration Modeler enables line-of-business
analysts to describe a new process using graphical tools and to put into that
process the steps that are necessary to integrate applications, people, and
processes across the business. The analysts can designate resources and
activities that are within the department, within the enterprise, or in any part of
an extended process.
Transform applications processes and data.
Transforming applications and data is the phase where you apply tools to help
you reuse existing applications in an e-business on demand™ environment.
This is all about transforming applications, processes, and data, whether
creating new business value from existing IT systems or maximizing
predictability, efficiency, and quality development overall. The IBM Enterprise
Transformation portfolio provides tools that enable you to:
Transform the user experience.
Convert green screens to a user-friendly Web interface, improve the
workflow and navigation of host applications, and provide host access
through a browser or portal.
Transform the connectivity.
Create Web services from CICS, IMS, or iSeries™ applications and
transform legacy processes into reusable, shareable business
