Report on the quality of production by the relay assembly test room operators. A list of the 23 most frequent causes of rejection of relays was made. The inspector recorded each kind of defect, the hour of assembly, and the operator for each...
Raw production and earnings data on an hourly basis for assembly group two with information on climate. Tables with weekly and monthy averages are included. Some handwritten notes are included, adding context to the figures.
Interviews with the relay assembly test room operators to find out why there was low inspection efficiency. The observer concluded that talking did not delay production, but probably decreased concentration. The group had the tendency to go fast...
Study of the workers reactions to a five-day workweek with standard hours versus a five and one-half day workweek with shorter days. Workers unanimously preferred the five-day workweek with Saturday morning off. Also included is the study that...
