XOX Corporation's management keeps track of the time it takes to process orders. During the most recent month, the following average times were recorded per order
Wait time 15.6
Inspection time 0.8
Process time 1.6
Move time 0.7
Queue time 3.9
Compute the delivery cycle time in days.
Percentage of manufacturing cycle time spent on non-value-added activities.
Super Fun Industries manufactures four top-selling toys code named A-148, B-356, B-457, and C-843. The following table shows how long it takes to process each toy through each required station. Note that all times are in minutes. Super Fun’s manufacturing plant is open 16 hours a day, 5 days a week, and 8 hours on Saturday.

a. If only toy A-148 is produced during a specific week, how many units could be produced? b. If weekly demand for the four products are A-148 = 200 units, B-356 = 250 units, B-457 = 250 units, and C-843 = 300 units, which station is the bottleneck, and is it capable of producing all the toys demanded?
