Information is cheap, powerful, but viscous ◊ One factory saved $30,000 the first year by… labeling the light switches ◊ A hard-drive factory saved a great deal of money by properly labeling the red/green-zone “idiot gauge” showing pressure drop in its big filter banks “Cents per drive” and “Million $ profit per year” (nonlinear) ◊ Innumerable facilities have saved untold energy and maintenance costs by measuring ◊ But many more use poor or uncalibrated sensors ◊ Few plants are designed to measure what’s needed ◊ And very few present key efficiency metrics to the operator, real-time, in effective graphics
