Companies run in this way have the special ability to foster employees’ deep feelings of personal responsibility (in contrast with the average company, where a recent Gallup survey shows that only 13 percent of employees say they are emotionally engaged with their company). They abhor complexity, bureaucracy, and anything that gets in the way of the clean execution of strategy. They are obsessed with the details of the business and celebrate the employees at the front line, who deal directly with customers. Together, these attitudes and behaviors constitute a frame of mind that is one of the great and most undervalued secrets of business success. We call it the founder’s mentality.
