Step 1: cut and shape the countertop from a section of Granite. It takes one worker 60 minutes to cut one countertop. Five workers work in the cutting area. Step 3: apply cement to appropriate surfaces. There is only one worker there who takes 8 minutes to do this part. Step 4: position and clamp a sink bowl under the countertop. It takes one worker 45 minutes to perform this step. There are 3 workers at this workstation. Step 5: The cement must dry for 2 hours. (This is not a workstation as no work is being performed.) Step 6: polish the edges of the top side of the countertop. It takes one worker 45 minutes to polish the edges, and 4 workers are positioned here. You are given a flow diagram for the process below. b) Based on the answer in (a), which workstation is the bottleneck? A. polish B. cut and shape C. position and clamp D. cut holes E. apply cement place. (Hint: multiply the hourly capacity of the bottleneck by 7.5 .) per day d) What is the throughput time in minutes? Round the answer to an integer. (Remember to include the 2 hours drying time.) minutes
