3. Bottleneck Analysis I A process requires six sequential steps with the following times. Assume only one machine at each step: i. Step 1: 2 minutes ii. Step 2: 3 minutes iii. Step 3: 2 minutes iv. Step 4: 4 minutes v. Step 5: 1 minute vi. Step 6:5 minutes 3.a Which step is the process bottleneck? What is the capacity of the process in units per hour? 3.b 3.c What is the capacity of the process (in units per hour) if a second identical machine is added to Step 2
