model dimension of governance, not on the total policy enforcement con-

text for IT policies. As such, it is an incomplete governance framework.

We will explore the many facets of SOA governance in the chapters that

follow so that you will not only understand what must be governed in order

to capitalize on a SOA initiative, but how to begin designing and imple-

menting SOA governance to ensure you realize the value of SOA. The rise

of SOA can be considered to be an inevitable evolution of IT based on the

industry adoption of key technology standards and the continued persis-

tence of IT integration and business agility challenges. Below we discuss the

SOA governance trend and how to enable SOA governance to be successful.

WHO ARE THE SOA STAKEHOLDERS?

One of the reasons SOA governance is more complex than IT governance is

that SOA governance adds many more governance requirements and pro-

cesses, and therefore more governance stakeholders, into the equation. In

addition, as we have emphasized, the fundamental difference between man-

agement and governance is that governance requires stakeholder represen-

tation. Governance is an oversight process that ensures appropriate

stakeholder representation for key enterprise decisions. Who are the stake-

holders in an SOA initiative? There are a multitude of SOA stakeholders, as

Exhibit 1.2 illustrates.

There are business stakeholders, which includes business unit execu-

tives who are concerned with driving revenue, sales, and proﬁt by servicing

customers with great products and services. These stakeholders are consum-

ers of IT resources and thus will also be consumers of SOA and services.

Their interests include the desire to increase market responsiveness and cus-

tomer service, while driving IT costs out of their business.

IT stakeholders include IT executives, enterprise architects, project

managers, business analysts, developers, and outsourcing partners. These

stakeholders represent the service provider roles in an SOA initiative. Their

interests include supporting business goals, increasing effectiveness of infor-

mation exploitation, increasing IT efﬁciency and reusing of architecture and

services, and speeding delivery of products and services to customers.

Service consumers are also stakeholders in an SOA initiative, as are ser-

vice providers. These two groups of stakeholders are joined by the SOA/

services development lifecycle process, which receives services requirements

and demand from consumers and then produces services that can be con-

sumed and composed into business processes and applications for end users

and customers. In fact, these stakeholders are best joined by re-engineering

the systems development lifecycle to accommodate SOA and services. In our
