Question
A (5 minutes) ----- B (4 minutes)----- C (6 minutes)
The diagram above represents a process with 3 steps. The activity time (in minutes) for one unit for each step is included within the diagram. Assume one worker at each step.
The demand for the product from this process is 7 units/ hour, and your company has decided they want to meet all customer demand. As the manager of this process, what should you do?
a) Increase capacity at Step A
b) Increase capacity at Step B
c) Increase capacity at Step C
d) Do nothing
Explanation / Answer
Correct Answer:
D
Working note:
The bottleneck step is C that has longest time of 6 minutes to process.
If the process starts empty, then Time to make first unit = 5+4+6 = 15 minutes
Time to make next 6 units = 6*6 = 36 minutes
So,
Total time to manufacturing 7 units = 15+36 = 51 minutes
Hence, capacity is not required to be improved.
