An executive cannot gradually dismiss details. Business is made up of details and I notice that the chief executive who dismisses them is quite likely to dismiss his business. Success is the sum of detail. It might perhaps be pleasing to imagine oneself beyond detail and engaged only in great things, but as I have often observed, if one attends only to great things and lets the little things pass the great things become little; that is, the business shrinks. It is not possible for an executive to hold himself aloof from anything. No business, no matter what its size, can be called safe until it has been forced to learn economy and rigidly to measure values of men and materials.
