"State and local government information technology leaders are in the transformation business.

Your on-demand constituency is clamoring for improved and available products and services.

It's your job to allocate limited IT resources to achieve the outcomes identified in your plan.

You must engage and rely on carefully selected vendor partners to supply the exact set of skills and tools to help you reach your destination.

The challenge is great, but the opportunities and options are greater. You are not alone.

- Dan Ross, Chief Information Officer, State of Missouri

Why is SOA relevant to State Gov’t?

Shared Services and Consolidation

Contrasting the Strategies

. . . Services Orientation as well as SOA is an architectural style whose goal is to achieve loose coupling among interacting services. A service is a unit of work done by a service provider to achieve desired end results for a service consumer. Both provider and consumer are roles played by organizational units as well as software agents on behalf of their owners.

. . . service-oriented architecture (SOA) is an approach to EA (enterprise architecture) where each major element is exposed as a “service.” The result is a distributed computing environment with a high level of interoperability between systems. . . . SOA enables the enterprise architect to “defy the laws of gravity” and combine and recombine software elements without the necessity of spending substantial amounts of time or money, assuming it has been implemented intelligently. (Eric Pulier and Hugh Taylor)



External mandates which impose standards & regulatory compliance

Improve operational efficiency – manage

costs

Acquisitions and mergers

Seamless access to infrastructure – any

time / any place

Silos of data – need for a consolidated view of

information & applications

Infrastructure is complex & heterogeneous

More demanding expectations for

personalized service - right now

Protect the security & privacy of critical

information assets

Need to streamline linkages with

partners & suppliers

Do more with less

Legacy system integration

Motivation for SOA Programs

Reducing cost to deliver solutions

Reducing time to deliver solutions

Reducing cost to maintain solutions

Reduced time to market

Increased utility from existing investments

Increased number of features available to the business

Motivation for SOA Programs


Government imperatives

Drive down cost

Integrate across departments and agencies

Reduce cycle times and costs for external constituents

Provide a flexible business model

e.g. US Federal Enterprise Architecture (FEA)

Reduce risk and exposure

Enhance revenue and collection

“Public sector executives face a unique set of challenges, including a management agenda that can change with each election, con-stant budget scrutiny and a heavy reliance on external providers.”

Holistic Enterprise ArchitectureEnterprise Architecture is a

management engineering disciplinethat presents a holistic, comprehensive view of

the enterpriseincluding strategic planning, organization,

relationships, business process, information, and operations.

The organization must be viewed as a fluid – changing over time as necessary based on

the environment and management’s response to that environment.

Capability

Now, Service Oriented Architectureprovides a new set of capabilities for

enabling the Agile Enterprise


SOA is an Enabling Capability

Are streets safer? Are this nation’s citizens healthier? Is healthcare available to those that need it? Is education available and effective in preparing our

citizens for the opportunities and demands of a new economy?

Is there the necessary economic development in this country to present employment, career, and personal development opportunities to our citizens?

Are we able to respond quickly and effectively to national emergencies such as natural disasters, pandemics, terrorist threats and attacks?

However, we must“…begin with the end in mind…”

Stephen Covey
