Service Integration has made the transition from novel concept to strategic imperative at most large enterprises. It is now seen as the key to solving all kinds of challenges—from improving the quality and consistency of IT services, to streamlining IT operations, to meeting the challenges of supplier management in an increasingly multi-sourced environment. The business value of Service Integration is very real. However, the meaning of the term seems to be in a state of flux, with different vendors defining it to serve their own interpretation. That is a serious issue because it means many companies are not accurately assessing the possibilities of Service Integration, implementing Service Integration solutions that truly align with business objectives, or extracting full value from Service Integration solutions.
