Our research on the success of top performing companies confirms the adage that “God is in the details.” Every company puts on its best effort when it is negotiating and executing a large order from its most important customer, when it is making a large capital purchase, when it is negotiating a large bank loan, or recruiting an executive to head up a critical activity. But the real test of a company’s quality and efficiency is not shown here. It is shown rather in the way the company handles the hundreds of small, routine, apparently insignificant acts that make up the bulk of our daily activities. The secret of non-stop profitable growth is to do the small things perfectly.
