A group of 10 workers were responsible for assembling hotplates. Anumber of different modles were manufactured. With small tools, each worker assembled part of a hotplate. The partiallycompleted hotplate was placed on a belt, to be carried from one assembly station to the next. When completed, an inspector would chek it over. The workers were paid a straight hourly rate and were supposed to take the same amount of time to complete their task. Morale seemed to be low, inspector found a relatively high percentage of badly assembled hotplaces. Rejects were caused by operator error rather than faulty materials were 23 percent. The workers decided they would build hotplats individually. Productivity climbed quickly. By the end of the year,productivity rose 84 percent higherthan during the first half of the year. Controllable rejects dropped from 23 to 1 percent during the same period. Absenteesim dropped from 8percent to 1 percent. Reject level was so low that inspections were done by the workers themselves. What changes in the work situation might account for the increase in productivity and tghe decrease in controllable rejects? 2. What might account for the drop in absenteeism and the increase in morale? 3. What were the major changes in the situation? Which changes were under the control of the manager? Which were controlledby workers? What might happen if the workers went back to the old assembly method?
