BPMN Essentials: Understanding Exclusive Gateways
Channel: YAWL User Group
Date: 2023-11-28

What is the role of the joining exclusive gateway in BPMN workflows? This video provides an educational overview of BPMN and workflow patterns, focusing on the "simple merge" pattern. It explains how this pattern involves merging multiple branches into a single subsequent branch, demonstrated through a Flash animation. Using examples of excavation tasks and estimating earth movement, the video illustrates how this pattern works in practice and warns against potential issues such as multiple tokens arriving at the merging point, which could lead to errors in process execution.

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