It's the Paper, Stupid --Dickeson

Weights and Measures

How shall we measure the waste? First, determine the pounds of paper required per thousand units of the finished job. Call that the M weight—the weight of the finished product. When multiplied by the count of actually delivered product units, we know the weight of the output. The pounds actually used are the input. Subtract output from input and the difference is waste—total waste. Subtract the cost of the waste directly from profit. That's the global aspect of waste.
