This is a small book which puts forward the idea that we must return to a better use of product cost data to make decisions. The authors review the literature going back to the first industries in the 1700's that used cost data in a managerial way. The work quotes heavily A. Chandler, J.M. Clark and Vatter for their contributions. It then reformulates their idea's and other historical data to come to the author's conclusion. In summary, it is well done for those interested in the subject and have an appreciation for business history.
