The IBM Component Business Modeling (CBM) framework is an

alternative to traditional views of a business - the building block of a

component business model is a business component

ceEach business component has

differentiated capabilities

Each business component defines

and decides on the use of all

resources needed to perform thedefined activities

Each business component has a

governance structure within which itmanages its activities

Each business

component hasbusiness services

which form the

interfaces to other

business

components

Business Component Elements

A component is a business in microcosm. It has activities, resources, applications,

infrastructure. It has a governance model. It provides goods and services (business

services)

We use a Business Component Map as a tabular view of the

business components in scope

Example component business model for the credit card industry

Columns are Business Competencies,

defined as large business areas with

characteristic skills and capabilities, for

example, product development or supply

chain.

A Business Component is a part of

an enterprise that has the potential to

operate independently, in the extreme

as a separate company, or as part ofanother company.

An Accountability Level

characterizes the scope and intent ofactivity and decision-making. The

three levels used are Directing,

Controlling and Executing.

Directing is about strategy, overall

direction and policy.

Controlling is about monitoring,managing exceptions and tactical

decision making

Executing is about doing the work

CBM can be very helpful in framing client issues

Example 2: sourcing


1.We can highlight non-differentiated capabilities

that present potential

opportunities for

alternate sourcing

What is Service-Oriented Architecture?

SOA in context

- a set of services that a business wants to expose to their customers and partners,

or other portions of the organization

- an architectural style which requires a service provider, requestor and a service

description

- a set of architectural principles, patterns and criteria which address characteristics

such as modularity, encapsulation, loose coupling, separation of concerns, reuse,

composability and single implementation

- a programming model complete with standards, tools and technologies such as

Web Services
