Forecasting Systems

When a company has several hundreds or thousands of products, the only viable approach is to perform the analysis frequently using a forecasting system. Some of the desirable factors of a forecasting system include the following:

Support for defining different hierarchies for viewing demand, units, product categories, and the ability to aggregate and disaggregate demand according to specific rules.

Ability to generate statistical forecast by applying time series methods. A good system will provide inbuilt ability to forecast at the SKU level, as well as at any of the group and characteristic levels defined above.

Ability to include external data, such as economic indicators, for regression analysis at the SKU, group, or characteristic levels.

Ability to combine two or more characteristics, and view demand and forecast for the combination. Such a feature can provide the analyst with valuable trend information related to specific product aspects that are of importance to customers.

The ability to perform “what if” simulations, with users evaluating the impact of changes before broadcasting changes to the entire company.
