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 .5 1 2 3 4 5 Refer to Scenario B: What would task 1 's utilization be? Pick the closest answer. 0% 20% 40% 60% 80% 100%
