2 Agenda What is SOA and Why the Hype? How does SOA mean for the Enterprise? Managing the SOA Journey 2

3 What is SOA? SOA Defined SOA is an emerging paradigm to integrate systems, applications, processes and businesses. SOA delivers differentiated business capabilities or products through the assembly of autonomous business and technology capabilities (services). SOA changes the way an enterprise is run by making the business process the focus. 3

4 SOA: Why the hype? What s new? SOA defines a business architecture of how separate business functions on autonomous systems inter-operate to execute a business process This business architecture is orchestrated by a separate mechanism rather than hardwired into the applications Differentiation on the outside Simplification on the inside Platform-neutral, Low-risk, Low-cost Agility Technology & process outsourcing Horizontal & vertical integration 4

14 Accenture SOA Approach: SOA Drivers The move toward SOA can be driven from a top-down approach (e.g., need for process optimization/automation), a bottom-up approach (need to establish a services foundation) or a hybrid of both approaches Need for a Services Architecture: Must create a services foundation to improve time to market and reduce integration costs (i.e., create a service wrapping to re-purpose legacy system and expose services to additional applications) Need for Process Automation: Must automate the core business processes with high ROI (i.e., automate corporate product provisioning process to save x million dollars) How ready is the enterprise architecture and the IT organization to implement SOA? Applications, architectures, processes and organizations must be evaluated Identify Driver (Process/Integration) Govern SOA Journey Define SOA Roadmap Strategy Assess Enterprise Architecture Readiness Execute SOA Roadmap 14

15 Establishing a Service Foundation or Process Automation? Considering their adoption drivers, organizations are focusing on building a services foundation or increasing their level of process automation. There are three possible approaches: Scope of Services Large / Cross Enterprise Medium / BU Realized Business Value Organization A OrganizationB High business value Organization A ( Services Focus ): Focused on establishing a comprehensive services foundation expanding from a department to the entire enterprise architecture. Organization B ( Iterative Processes/ Services Focus ): Focused on a mix of business process focus and services focus. Small / Dept 0% Automated low business value Organization C Semi Automated Degree of process automation Organization C ( Processes Focus ): Focused purely on creating business processes that may span from a department to the entire enterprise with a small services footprint. 15
