Consider the process described by the process flow diagram below. Each box describes an activity along with time required to carry out the activity, and the arrows show direction of the flow of material between activities.

Suppose Stan carries out activities A and F, Kyle carries out activities D and E, Eric carries out activity B, and Kenny carries out activity C. Given this resource allocation, which of the following change will NOT reduce the capacity of the process (i.e., the maximum number of jobs the process can finish per day)?

Group of answer choices

Time for activity C increases by 1 hour

Time for activity B increases by 1 hour

Time for activity D increases by 1 hour

Time for activity E increases by 1 hour

Which of the following is NOT always true about a critical activity?

Group of answer choices

A critical activity is an activity on a critical path

A critical activity is performed by a bottleneck

A critical activity has no slack (i.e., slack = 0)

Consider the hiring process in a company. During the process each job candidate goes through three activities: Verification, written test, and interview. Verification takes 1 minute, the written test takes 40 minutes, and the interview takes 15 minutes. Assume there is one clerk carrying out verification, 10 examiners carrying out written tests and 3 interviewers carrying out interviews.

If utilization of the clerk carrying out verification is 0.1 (i.e., 10%), what is the utilization of the bottleneck resource?
