A large product line can be the source of significant buried costs: extra inventory, raw materials, packaging, labels, as well as sub-optimal production scheduling.
The chart on the right shows the profit contribution by product for a specialty company with over 1,000 SKUs. It shows a long tail of low profit products.
Yet, while the majority of profits come from the top products (the bottom 900 generate less than 40%), there are significant profit contributors in the tail ("D" & "C" groups).
Culling the bottom "D" and "C" products is a starting point, but would be overly simplistic. What type of customers are buying them? Who would be impacted?
