A process in a medical lab is designed to have 7 steps (A, B, C, D, E, F, and G) with activity times of 4, 2, 3, 4, 5, 4, and 10 minutes, respectively. All activities happen at a single station except activity G which has three identical stations all individually manned. Therefor the combined capacity of the stations preforming task G is 3.33 min/unit. A manager has gathered some data and determined the process actually produces 6 units each hour and that it takes 40 minutes for the average unit to move through the system. The cycle time efficiency of the system is most nearly? O 50% O 63% O efficiency exceeds 100 percent
