On the Workflow templates tab, you can see all of the workflow templates that you have created (or are an admin for) and how many workflows are past the due date, ongoing, and scheduled. 

On the Workflows tab, you can see all the tasks that have been assigned to employees in the workflows that you are an admin for. 

If you are not an admin of the workflow, you will not be able to see the other tasks in the workflow unless permission has been provided by the workflow admin(s).

On the My Tasks tab, you can see any tasks that have been assigned to you.
