Prologue :

Components that come in different shapes, sizes, and colors

Interfaces that know how to connect to and interact with each other

Reusableto assemble and create new things

that are greater than the sum of parts

Scalableto add new bricks to meet increase in user requirements

Interoperable with any bricks from different packages (platforms)

SOA (Service Oriented Architecture)

A system architecturein which business functions are built

as components (services)

that are

loosely-coupledand well-defined

to support interoperabilityand

to improve flexibilityand re-use.

Approaches

The Five Levers Model

Centralize

Bring operations under a single authority to reduce

overhead costs and create a single decision-makingauthority to manage risk

Standardize

Reduce the variety and variability of processesdelivering similar outputs to further reduce costsand minimize risks.

Modularize

Deconstructthe system into its componentsubsystems and standardize interfaces for futurecost reductions.

Optimize

Eliminate redundant steps, substitute lower-costcomponents, out-task appropriate elements,streamline remaining operations, and instrument theprocess for monitoring and control.

OutsourceDrive processes out of the enterprise entirely tofurther reduce overhead, variabilize costs, and

minimize future investment.

The Idea in Practice

Describe your operations in terms of desired outcomes.

Identify the activities supporting your desired

outcomes.

Identify the capabilities supporting each of youractivities.

Identify activities most critical to your companyssuccess.

Design a more efficient operating model.

Building or buying SOA software should be the last not the first

step in creating a new operating model.
