For the business process flow chart given in Figure 4, where the activity times are given in Table 4, calculate the cycle time efficiency. Table 4 shows the activity time and the resource type needed by each activity as well. For the first loop shown in Figure 4, assume that after re-work the probability of an error remains the same and re-work may be done any number of times. For the second loop shown in Figure 4, assume that re-work is allowed only once. There is 10 unit of resource R1 and 20 units of resource R2.

(a)Calculate the average cycle time for this process [2 marks]

(b)Calculate the pool capacity of each resource and identify the bottleneck.

(c) If the actual throughput is 10 job per hour, what is the business process capacity utilisation? [2 marks]
