Each level for each attribute provides levels of visibility but also provide varying levels of effectiveness or ineffectiveness. The most common forecasting hierarchies are:
Are there two or more levels of aggregation?
Despite all the potential attributes, levels of aggregation, and combinations of them, historically the debate has been condensed down to only two options, top down and bottom up,
