Crew Pro Sprint Activity Diagram shows the system's behavior at a given time. As the sprint activity diagram (AD) suggests, an activity diagram shows business and software processes as a progression of actions. People, software components, or computers can carry these actions out. Activity diagrams are used to describe business processes and use cases and document the implementation of system processes. Depending upon your requirements, you can make an activity diagram as required. Such Activity Diagrams include swimlanes, parallel flows, control nodes, object nodes, expansion nodes, and more. It should be noted here that Join Nodes are introduced to support parallelism in activities. Join node is a control node with multiple incoming edges and one outgoing edge and is used to synchronize incoming concurrent flows.
