High Output Management

by Andrew S. Grove

Indicators tend to direct your attention toward what they are monitoring. It is like riding a bicycle: you will probably steer it where you are looking. If, for example, you start measuring your inventory levels carefully, you are likely to take action to drive your inventory levels down, which is good up to a point. But your inventories could become so lean that you can’t react to changes in demand without creating shortages. So because indicators direct one’s activities, you should guard against overreacting. This you can do by pairing indicators, so that together both effect and counter-effect are measured. Thus, in the inventory example, you need to monitor both inventory levels and the incidence of shortages. A rise in the latter will obviously lead you to do things to keep inventories from becoming too low.
