What is the supervisor's responsibility to the wage incentive program 1 Does it include the responsibility for rate setting, for standing on the manufacturing floor with a stop watch, putting pencil marks on a time study form? This has been tried before, early in the history of time study. When the idea first occurred of paying a man for the amount of work he performed, the question arose "Who is to de-termine how long it takes to do a job so that management will know how much to pay?" In almost every case, management assumed that this time could best be determined by the man who knew most about the job.
