Most business processes depict real-life, business or scientific scenarios, which need the interactions of a human at least once in its workflow design. Typically, these interactions are initiated by the process itself, and requests a user input to proceed. These human interactions, which are initiated by business processes are referred to as Human Tasks.
After deploying Human Tasks, you can use the Human Task Explorer of the Business Process profile to explore it. To do this, in the Management Console, click Main → Manage → Processes → List → BPEL and click the Process ID of the deployed process.
