If you happen to be a Workflow Manager you will have one extra option in the workflow too bar to help manage the Work Triggers you have management authority over.
Click the Workflow Manager button in the Workflow drop down from the tool bar.
This will open the Workflow Manager Console to show you the performance of all Work Triggers you have rights to. You can narrow the reporting by using the Filters and Sorting section on the left.
The Current Work Items tab shows the work items that are currently active.
The Work Item History tab shows the work items that have been completed.
The Charts tab show you several graphical charts that correspond to the current and historical work items including Overall Performance, Active Items, Completed Items and average wait and completion times.
