Question 9 1 points Save Answer Consider a system that consists of six activities that must be completed in series (one after the other, as we have seen in many examples), with the fourth activity being the system bottleneck, as shown below. Bottleneck Which of the following statements will always be TRUE: a. Assuming that all activities attempt to work at their full capacity, it is possible for some of the activities that are upstream of (before) the bottleneck to achieve 100% utilization, but it is not possible for any of the activities that are downstream of (after) the bottleneck to achieve 100% utilization. b. If the capacity of the bottleneck is doubled, then the capacity of the system will be doubled. C. Assuming that all activities attempt to work at full capacity, the utilization of the activities that are downstream of (after) the bottleneck will be 100%. d. All of the above are true. Oe. None of the above are true
