If a task is estimated to take nine hours over three days, how should the duration and planned hours be set up?

The correct answer indicates that the duration is set to three days while the planned hours are set to nine. This is accurate because duration refers to the total time allocated to complete a task, which in this case spans three days. The planned hours represent the total amount of work time anticipated to complete the task, which is nine hours.

When a task is expected to take nine hours spread over three days, it means that the work is either spread evenly each day or might not be worked on every day but still needs to accumulate to nine hours by the end of the duration. Therefore, setting the planned hours to nine reflects the total effort required, while the three-day duration captures the timeframe over which that effort will be distributed.

To solidify understanding, if someone were to choose a different setup, such as adjusting the planned hours to merely three, it would misrepresent the actual effort needed; it suggests only three working hours are allocated. This conflict in understanding the relationship between duration and planned hours could lead to mismanagement of resources and scheduling. Hence, the combination of three days for duration and nine hours for planned hours aligns correctly with the description of the task's requirements.
