The Full Form of JBPM is‍ Java Business Process Model.

A Business Process is a collection of actions that take place in your company, revolving around a specific business practice. These processes can involve a variety of participants and might include internal and external computer systems or personnel. In Oracle Java CAPS Business Process Manager (BPM), you create a graphical representation of the Business Process called a Business Process model. The model defines each component in the process and the flow of data through those components.

The Business Process model indicates the flow of data from start to end, and can include activities performed by the software, decision points, and any business logic used to transform and transfer the data. A Business Process can also contain activities that must be performed by a user, meaning that the flow of data is paused until the specified user performs the required activity.

Business Process components, or modeling elements, include activities, branching activities (decision points), intermediate activities, and links, as well as the business rules that define the logic of how data is transformed and moved. You can create sub-processes that can then be incorporated into a main Business Process.

The modeling elements you add from the Business Process Designer are standard BPEL elements, and are described in detail in Business Process Activities.

By default, the Start and End activities appear on the blank Business Process Designer as soon as you create a Business Process. There is only one starting point for any Business Process model. There can be multiple end points.
