Here I explain, what the Increased Return on Investment goal is and why it is so important in an service oriented architecture.
What is the Increased ROI goal?
What are the cost-savings of reuse in it-systems compared to the cost of producing an it-system from scratch. Reuse is achieved through agnostic solution logic (which can be used in multi-purpose), which is supported through the intrinsic interoperability goal. Silo-based applications on the other hand have an complex environment with an ever-growing integration architecture and therefor have intensive cost for operation and maintenance.
