need to make work order scheduling to be maintained to match the following case

Summary:

If we produce 1 quantity of Product X, which takes 1 labor unit and 3 hours of required usage, the lead time for this 1 quantity will be 3 hours.

However, if we have a work order for 5 quantities of Product X, the total time required should be (5 quantities * 3 hours) = 15 hours.

If I increase the assigned labor units to 3, the expected behavior should be:

Each assigned labor unit will work for 3 hours to produce 1 quantity of the 5.
-The first labor will work for 3 hours, the second labor will work for 3 hours, and the third labor will work for 3 hours.
The first, second, and third labor work at the same time, so the cycle time is 3 hours for 3 produced quantities.
