False

If the sum of the task times required to produce a product is 80 minutes and the cycle time for the same product is 15 minutes, the theoretical minimum number of workstations is 8 using the assembly-line balancing procedure.

True

In assembly-line balancing, the theoretical minimum number of workstations is found by a ratio of the sum of all task times divided by the cycle time.
