This operations management lecture covers methods to measure forecast accuracy. These include the mean absolute deviation or MAD, the mean squared error or MSE, and the mean absolute percent error or MAPE. It also covers the tracking signal and forecasting control charts. It concludes with a discussion of how to deal with adding a large customer, losing a large customer, and a temporary disruption in demand.
