Task cancellation in BPMN: How tasks are withdrawn or halted mid-execution. This video explores the cancel task pattern in BPMN, where an enabled task is withdrawn before execution, or if already running, it is halted and removed. Using the example of insurance assessors assessing damage, it demonstrates how one assessor's task can be canceled when the other completes their assessment. The BPMN modeling involves signal events, showing how tasks are canceled in the workflow.

This video is part of a series on modeling the workflow patterns with BPMN.
