Services-Oriented Architecture?

The Problem

• IT organizations often focus on implementing technology yet not enough on helping a customer organization accomplish its missionenough on helping a customer organization accomplish its mission. This problem becomes critical for any organization in Today’s “bonkers” environment.*

T d ' IT l ti t d t b b d COTS hit t th t• Today's IT solutions tend to be based on COTS architectures that often enforce specific business processes and lack open technology upgrade paths– Flexibility: Large-scale COTS applications have limits on theirFlexibility: Large scale COTS applications have limits on their

configurability, so the application does not readily support the organization’s continuously changing processes

– Technology Upgrade: Upgrading or replacing technology is often very difficult that hinders the organization in achieving its mission with thedifficult, that hinders the organization in achieving its mission with the current IT technology

• Therefore, too often the organization conforms to the IT needs, instead of IT conforming to what the organization requires

SOA as a Solution

• Service Oriented Architecture (SOA) assists the organization with f i it IT l i b i blfocusing its IT on solving business problems– Measurably links the applications to the organization’s processes to enable

the organization to understand the contribution of each application within the process. This enables the organization to determine whether itsthe process. This enables the organization to determine whether its investment is worthwhile

– Provides “line-of-sight” or Traceability• From the Organization’s Mission through its Strategies to its Processes to

determine the optimal place for the next investment • To support the intent of the Federal Enterprise Architecture (FEA), a concept

which is being incorporated into the DoD Architecture Framework version 2

SOA as a Solution

(Continued)

• The SOA enables the organization’s IT to support continuous hprocess change

– Existing “composite” applications can be reassembled to support a change in the organization’s processes in a Continuous Operational and Development Environment (CODE)Development Environment (CODE)

– The “Composite” applications are the Services and are assemble from Service Components, each of which is a separate application (which may be a Web Service)

• Each Service Component may be upgraded to new technology or replaced independently

• These Service Components are assembled using a process flow which may be redesigned independently of the components being used g p y p g

ID-SOA™

• A good SOA process will help management to: Id tif d IT t th t d i i i l l– Identify processes and IT systems that are producing minimal or no value for the organization, that is, IT systems that are good candidates for investment

– Recommend deletion or investment (by updates/upgrades or replacement)– Execute projects that the customer has approved as IT investments– Evolve toward a service-based business vision/model with the agility to

successfully respond to unexpected challenges and opportunities

h d d SO ll h• In other words, a good SOA process allows the organization to use an IT investment process to optimize its processes and the supporting IT systems and applications in a CODE

• Northrop Grumman’s Investment-Driven Service-Oriented Architecture (ID-SOA™) is such a process
