If you look at Page 4 of The Foundation® FastTrack, you will see the number of units each product has sold in the previous year (in thousands). These numbers will help you determine how much capacity is appropriate for your product.

The Segment Analyses and the Market Share report will breakdown these sales on a segment by segment basis. So if you are inventing a brand new High Tech product which is positioned outside of the Low Tech circle, you can base your Capacity purchase on what yours or other products have sold within that segment.
