I find unplug and play a useful phrase in talking about service-oriented development directions. My use of it derives from Phil Wainewright’s Loosely Coupled site:
The progression is that web services are providing the infrastructure for service-oriented architecture, which enables enterprises to begin to assemble new composite applications by joining together elements of their existing software investments. The loose coupling inherent in the architecture allows them to do this rapidly in small, tactical projects, spurring the adoption of agile development techniques. Driving all of this is a desire to achieve greater business process agility, and there is a dawning recognition that this can only be achieved by unplugging rigid integrations and embracing the concept of continuous change — in short, unplug and play.
