The business process component in WebSphere Process Server implements a WS-BPEL compliant process engine. Users can develop and deploy business processes with support for long and short running business processes and a robust compensation model in a highly scalable infrastructure. WS-BPEL models can be created in WebSphere Integration Developer or imported from a business model that has been created in WebSphere Business Modeler.

• Human Tasks

Human task in WebSphere Process Server are stand-alone components that can be used to assign work to employees or to invoke any other service. Additionally, the Human Task Manager supports the ad-hoc creation and tracking of tasks. Existing Lightweight Directory Access Protocol

WebSphere Process Server supports multi-level escalation for human tasks, including e-mail notification. WebSphere Process Server also includes an extensible Web client that can be used to work with tasks or processes. This Web client is built based on a set of reusable Java Server Faces (JSF) components that can also be used to create custom clients or embed human task functionality into other Web applications.

• Business Rules

Business rules are a means of implementing and enforcing business policy through the externalization of business. This allows dynamic changes of a business process for a more responsive business environment. Business rule authoring is supported by an Eclipse
