The Principles of Scientific Management

94 THE PRINCIPLES OF SCIENTIFIC MANAGEMENT it was found to be necessary to measure the output of each girl as often as once every hour, and to send a teacher to each individual who was found to be falling behind to find what was wrong, to straighten her out, and to encourage and help her to catch up. There is a general principle back of this which should be appreciated by all of those who are espe- cially interested in the management of men. A reward, if it is to be effective in stimulating men to do their best work, must come soon after the work has been done. But few men are able to look forward for more than a week or perhaps at most a month, and werk hard for a reward which they are to receive at the end of this time. The average workman must be able to measure what he has accomplished and clearly see his reward at the end of each day if he is to do his best. And more elementary characters, such as the young girls inspecting bicycle balls, or children, for instance, should have proper encouragement either in the shape of personal attention from those over them or an actual reward in sight as often as once an hour. This is one of the principal reasons why coopera- tion or “profit-sharing” either through selling stock to the employés or through dividends on wages received at the end of the year, etc., have been at the best only mildly effective in stimulating men to work hard. The nice time which they are sure to have to-day if they take things easily and go slowly proves more attractive than steady hard work with a possible reward to be shared with others six months
