The following diagram shows a 4-step process that begins with Operation 1 and ends with Operation 4. The rates shown in each box represent the effective capacity of that operation. 12/hr 15/hr 11/hr 14/hr Operation 1 Operation 2 Operation 3 Operation 4 a. Determine the capacity of this process. Capacity per hour b. Which action would yield the greatest increase in process capacity: (1) increase the capacity of Operation 1 by 15 percent; (2) incroce the capacity of Operation 2 by 10 percent; or (3) increase the capacity of Operation 3 by 10 percent?
