To measure a person's physical health, physicians use certain standards — proper weight, cholesterol count, lung capacity, and the like. Without ever seeing the patient, a doctor can predict health and longevity based simply on the numbers. Similarly, you can track the health of your business using what I call baseline numbers. And just as a physician may prescribe a workout to help you lose weight, you can use your baseline numbers to diagnose business problems and decide on a course that will improve your company's performance.
