"The experience curve says that your costs should probably decline by 15% or 20% with every doubling in your experience making a product, approximately how many of them you turn out. It also says that if you have the biggest market share, meaning the most experience of anybody in your competitive set, you should have the lowest costs, and the resultant capability to underprice your competitors, maybe forever. The abiding lesson of the experience curve is that companies need to discipline themselves to keep reducing their costs, year in, year out, if they are to remain competitive."
