What task setting needs to change to allow 4 users to complete a task originally planned with a 10-day duration in less than 3 days?

To enable four users to complete a task originally planned with a 10-day duration in less than 3 days, it is necessary to change the Task Duration Type to Calculated Work. This is because Calculated Work accounts for the number of resources assigned to a task and how those resources can affect the overall duration.

When using Calculated Work, the system adjusts the task duration based on the total available work hours contributed by the assigned users. In this scenario, if the task originally requires 80 hours of work (10 days with one user working 8 hours per day), assigning 4 users can significantly reduce the time it takes to complete the work, depending on their availability and allocation. Thus, with a sufficient number of resources, they could theoretically complete the task in less than 3 days.

Effort Driven – which is the alternative option – allows for the duration of the task to change based on how many resources are allocated. However, it might not reduce the duration in this case sufficiently to meet the requirement as directly as Calculated Work would, since effort-driven duration is focused primarily on maintaining the same total work effort rather than dynamically adjusting the completion time given the resources.
