If you record time against tasks, you can report on the difference between the estimated time and the actual time recorded against them. You can use this report in any workspace and report across all of your workspaces and their members.
You will find a link to this report in the summary panel of the task area in a workspace. You can filter on Users, Workspaces, the state of the tasks (whether they are completed or not), as well as being able to filter by date.
The report will display the estimated time against the time that’s actually recorded and calculate the difference. To give a quick visual representation, if the estimated time is exceeded the difference in time will be highlighted in red. Alternatively if the estimated time has yet to be met the difference will be displayed in green.
The results can be download to CSV for easy analysis.
