A workflow is complete when it reaches the End activity, even if there are still active branches of the workflow in progress. To ensure that both branches are completed, add a Join activity to resolve the branches.

For example, the following figure shows a workflow with two branches that execute independently. When Task 1 and Task 2 of Branch B are completed, the workflow is marked complete even if the Branch A tasks are not completed.

Figure 1. Workflow with uncompleted branch

For both branches to complete, add a Join activity to resolve the branches. When one branch reaches the join, the workflow waits for the other branch. When both branches are complete, the workflow reaches the end. The Incomplete condition of the a Join activity is met only if one of the branches cannot be completed.
