But most importantly, the process dependencies are also clearly exposed through interfaces(business services in Business Modeler). This effectively means that a process modeled in this way is a component in the sense that it embodies the most fundamental property of components: a component declares the services it provides and those that it depends on Cohesion is another property that is typically associated with software components and that is also highly desirable in the context of business process modeling. While the idea behind component cohesion may be simple( keep related functionality together), it does require good analysis skills to achieve. The number and comple of process dependencies may provide a measure of process cohesiveness; the exity lower the number of dependencies and the lower the dependency complexity, the more cohesive a process tends to be If we agree that business processes are components if they(1)are cohesive and(2) expose services and dependencies, then "component-oriented business process modeling" is an adequate term to describe the activity of creating such process models. This notion of business processes as components is not one that is exclusive to the technical or implementation domain. A component view of a business is also sary for greater business agility. Thus if your goal is to better align business with technology, and to easily respond to changing business requirements, then the use of components in one domain necessarily implies a component view in the other Figure 3. a process component exposes its services and its dependencies Model business processes for flexibility and re-use: A component-oriented approach o Copyright IBM Corporation 2009.
