Management Is Prediction --Dickeson

Managing means predicting. When we say, "Until you measure you can't control," we're really saying, "If we don't record the past we can't predict what's going to happen."

If we haven't kept track of what we've spent for wages, salaries and social benefits in the past, we can't project those expenses for the future. If we haven't accounted for production time, we can't predict delivery dates. The better we predict, the better we can manage.
