Army experience with a small mechanized stock accounting system, the NCR 500, was studied with respect to personnel and training, in order to improve implementation of newer and more complex computer-based logistics systems. Officers and enlisted personnel in various duty positions connected with NCR 500 systems in four Far Eastern commands were interviewed. Data showed there had been a continual input of underskilled personnel into nearly all of the duty positions in the mechanized stock accounting system and at its major interfaces. Interviews indicated that efficiency would have been promoted by (1) integrating NCR 500 procedures and concepts with repair parts supply procedures and concepts, (2) a total systems approach to training, (3) upgrading the storage operation as well as the supporting stock accounting system, (4) assigning more well-qualified technical supply officers, and (5) training in the NCR 500 system for more noncommissioned officers with repair parts supply experience.
