id SOA as a contributing factor in managing enterprise software

SOA or bust??

what’s a portal? simplify, streamline, and expedite the entire process of interacting with a corporation

Provide an inviting and secure web-based interface to a diverse range of corporate information, services and applications.

Directly interact with a corporation without having to deal with a representative.

Reduce operational costs while increasing company reach

what is SOA? Service Oriented Architecture Neither a technology or a technology standard.

Technology independent, high level concept that provides architectural blueprints

SOA is a business design discipline

why design… SOA what? key driver for SOA

Agility

Meet the Business

Meet the I.T. Guys and Gals… err… folks???

Challenges to Agility Develop a solution

Project management and SMEs move on to new projects

No more political support Tight budgets = changes & fixes aren’t done properly

Critical structuring decisions made on the side without proper control.

enterprise Solutions are unique tightly coupled with the internal organization, processes and business model of the enterprise

large numbers of different requirements from various departments

heterogeneous teams, political environments, heterogeneous technologies

cross dependencies between functional requirements

SOA Ground rules The IT organization will partner with the line of

business managers to create a high-level map of what the business will look like.

The IT organization will create a flexible structure that will turn key IT software assets into reusable services that can be used no matter how the business changes. These services will include everything from business processes and best practices to consistent data definitions to code that performs specific business functions.

The IT organization will use only accepted industry standards to link these software assets together.

The IT organization will use the service oriented architecture concepts to begin to create business services that are consistent with the way the business operates.
