The single reason that you use IT within your organization is for service enablement. IT has proven itself to be essential to provide the levels of service that customers demand. Implemented well, the operating costs of IT systems provide many opportunities to serve customers’ needs and provide operating margins commensurate with the profitability demanded by the organization’s stakeholders. Now, the concept of business services is being embraced by enterprise IT organizations through the adoption of the Service Oriented Architecture (SOA) paradigm. SOA is IT’s response to the demands from the business that IT be more in tune with the needs of the business. By moving from a software systems development paradigm to a business service development paradigm, it is hoped that IT departments and business units will become more aligned.
