Session 2 Operations Management 6 Bottleneck Analysis The stove, operating 100% of the time, can push out:  20  hamburgers / 45 seconds = 0.44 hamburgers per second. The workers, operating 100% of the time, can push out:  10  hamburgers / 15 seconds = 0.66 hamburgers per second. The stove is the  bottleneck  resource; it pushes out the  slowest amount of hamburgers per time period. There is no reason to hire another worker at any cost. Having an additional worker does not speed up the hamburger delivery process.
Session 2 Operations Management 7 Capacity Definition:  The number of units, per unit of time,  that can be processed. Examples:   The capacity of the Macdonald’s in the previous example  was 0.44 hamburgers per second, or approximately 26  hamburgers per minute.   (Note:  Units are important!) A bank can serve 100 customers per day  The capacity of a server is 30000 hits per min.
