The minimum planned effort for the completion of a task that is part of a change or project was one minute. But because more and more tasks are executed automatically, it is now possible to set the Planned effort fields to zero (or 00:00).
Setting the planned effort of an approval task to zero may also be useful in cases where the approval needs to be provided by a customer whose effort should not be considered when estimating the total effort for a change or project.
A small usability enhancement has also been added to make it easier for change and project managers to add approvers or assignees to tasks. When another person is added to a task, the planned effort for the new person is automatically set to the planned effort of the previous assignee.
This ensures that the manager of a change or project only needs to set a planned effort for the first assignee of a task, rather than specify the same planned effort for each assignee individually. Only in the relatively exceptional cases, where a different planned effort needs to be specified for each assignee, would the manager need to manually enter a value in the Planned effort field after selecting an additional assignee for a task.
