In business success is measured by profits. That's how you keep score. That's how you are judged.
Management styles come and go, profit or loss is always there.
The past few years have seen the Quality Revolution, Management by Objective, Management by Walking Around, Employee Empowerment, Teams, Site Based Management and dozens of other business philosophies intended to help owners and managers build successful companies. It's easy to be so caught up in these movements you forget why you are in business in the first place. Profits are a measure of your competence as a businessperson. Profit serves to let you know if you are on track and if the product or service you offer the marketplace is really needed. In a free market consumers vote with their pocketbooks.
