Scenario The process of a firm is as follows. Flow units enter at the rate of 5 units per minute. All units wait in line for Step A and then do Step A. Then about 65% go to wait in line for step B. When flow units finish Step B, 100% exit. About 35% of the units leaving Step A go to Step C. After Step C, 100% of the flow units that went through Step C goto Step D. After Step D, 100% of the flow units that went through Step D exit. On average 3 units are waiting for Step A and it takes 1.5 minutes to do Step A. 1 units waiting for Step B and it takes 6 minutes to do Step B On average 4 units are waiting for Step C and it takes 3.5 minutes to do Step C 2 units waiting for Step D and it takes 3 minutes to do Step D On average On average 1 Create a process flow diagram of the above scenario in the space below. Be sure to label each Activity (A, B etc) and include the buffers. Also, include the variable for Little's Law below the symbols.
