Number of Forecasts
The third set of questions concerns how many forecasts you need, and this is a function of the following:
1. At what levels, time horizons, and intervals are forecasts required?
2. How many products, that is, product lines and product items (SKUs), must be forecast?
3. In how many distribution channels are your products marketed?
4. How many product/location combinations (e.g., by sales regions, distribu- tion centers, individual customers) must be forecast?
