Suppose you have a four-activity sequential process. Throughput capacities in units per minute are shown in parentheses:

Task 1 (3) ---> Task 2 (4) ---> Task 3 (2) ---> Task 4 (5).

No buffers exist between tasks, so an upstream task must wait if the downstream task is busy.

What is the actual throughput rate for the sequential process as a whole (i.e., at what rate would units exit task 4)? Pick the closest answer

a)0.5 b)1 c)2 d)3 e)4 f)5

What would task 1's utilization be? Pick the closest answer.

a)0% b)20% c)40% d)60% e)80% f)100%
