Once this roadmap is laid out, organizations need to identify the infrastructure services required for delivering business solutions. The core of SOA is to lay that blueprint which depicts the design and build that enables organizations to transform itself to the needs of the business, proactively enabling IT to deliver global solutions, with reduced application and infrastructure complexity, increased reuse of business services and orchestrate service capabilities. As business demands new processes or change to existing processes, the SOA blueprint enables building the IT infrastructure in tandem with business to enable them realize quick wins.
