Development and Evaluation of a Simple Job Performance Aid for M151A1, A2 Truck Operators
Abstract
This report describes the development and evaluation of a prototype job performance aid for M151A1, A2 truck operators. The job performance aid was formatted as a checklist and was derived from a consolidation of operator checks describing the standards of maintenance on the vehicle for the operator and his supervisor. The job performance aid was evaluated in comparison to the operator's technical manual (TM 9-2320-218-10, August 1978). Twenty soldiers were randomly assigned to the job performance aid condition or the technical manual condition, and to one of two vehicles. Each soldier inspected a vehicle using the performance aid or the technical manual, and performance was assessed in terms of the percent of faults found by the soldier in relation to the actual number of faults on the vehicle. Using the job performance aid resulted in better performance than using the technical manual in terms of the percent of faults found (29.8% vs. 10.2%).
