. Demand planning is the same as forecasting. 2. All forecasts should include two estimates: an estimate of the demand and an estimate of the forecasting error. 3. Forecasts are more accurate at the individual level compared to a group level. 4. Tracking signal is the ratio between cumulative forecast error and the most recent estimate of mean absolute deviation. 5. Actual demand is always equivalent to actual sales. 6. Increasing the flexibility of operations and the supply chain is a main method for counteracting forecast error. Multiple Choice (2 points each, please do NOT show your work) 1.
