When pressed to offer commodity-related cost reductions, suppliers may argue that the effects of raw material prices on their own costs have been smaller than estimated, have been diluted by other players in the value chain, or have yet to trickle through to them. Without a deep understanding of the whole value chain and such facts at their fingertips, companies find it very hard to counter these points.
To claw back the full savings potential offered by commodity price drops, companies need to develop a detailed picture of the end-to-end value chains of their products, and of the way input cost fluctuations percolate through that chain. That is a complex business, requiring an understanding of the underlying chemistry of key raw materials, the structure of the industries that produce those materials, and the evolution of supply and demand over time.
Companies that have taken such a fact-based and structured approach to supplier negotiations in the response to commodity price changes have been able to capture savings of 4 to 6 per cent from their suppliers in a wide range of categories. One large apparel retailer did this by building a “rapid response system” based on detailed analysis of the effect of commodity price changes on the costs of different yarn and fabric types. Significant swings triggered assertive communications with its suppliers, asking for price adjustments within 30 days. The company was able to support subsequent negotiations with the data from its analyses.
