Complexity is a fact of life in information technology (IT). Dealing with the complexity while building new applications, replacing existing applications, and keeping up with all the maintenance and enhancement requests represents a major challenge.

If all applications were to use a common programming interface and interoperability protocol, however, the job of IT would be much simpler, complexity would be reduced, and existing functionality could be more easily reused. After a common programming interface is in place, through which any application can be accessed, existing IT infrastructure can be more easily replaced and modernized.
