Welcome to the world of Predictive Demand/Supply Planning whose mission is to predict imbalances as far in advance as possible, in order to provide ample time and opportunity to design and implement corrective Sales & Operations solutions.

So how do we design a system for identifying potential issues and expressing them via a commonly understood key process indicator (KPI) where the cause and effect of our actions can be readily measured?
