Curam supports the ability for a Task to have a 'deadline', which is the reasonable amount of time for a User to complete the Task.

If the deadline passes and the Task has not been closed, the Workflow Engine notifies the specified deadline handler that Task has not yet been closed.

Similarly, an Event Wait can have a 'deadline', which is the reasonable amount of time for an event to occur in the system.

Example

You define a workflow (Process Definition) to allow correspondence to be sent to customers whenever their payment details change.

Person John Smith's payment details change due to an increase in rates. This increase raises an event which causes the Workflow Engine to enact your workflow and create a Process Instance.

The system prints out the letter and assigns a Task to User Ronan Rooney to post the letter. Your Process Definition specifies a deadline time of one day for the letter to be posted.

User Ronan Rooney is called away from the office and does not complete the Task. After one day has passed the Workflow Engine invokes your specified deadline handler, which reassigns the Task to Ronan's supervisor.
