Keyword | effort

Purpose | Specifies the effort needed to complete the task. An effort of `6d` (6 resource-days) can be done with 2 full-time resources in 3 working days. The task will not finish before the allocated resources have contributed the specified effort. Hence the duration of the task will depend on the availability of the allocated resources. The specified effort value must be at least as large as the timingresolution. WARNING: In almost all real world projects effort is not the product of time and resources. This is only true if the task can be partitioned without adding any overhead. For more information about this read The Mythical Man-Month by Frederick P. Brooks, Jr. Tasks may not have subtasks if this attribute is used. Setting this attribute will reset the duration and length attributes. A task with an effort value cannot be a milestone.
