An Evaluation of a Job-Aiding Tool for an Inspection Task

Abstract

Various job aids have been developed to improve visual-inspection performance. Many of the job aids have been developed with the purpose of training inspectors to adopt systematic search strategies. While various research has shown that systematic search strategies are superior to random search strategies, exactly what systematic search strategy constitutes the most efficient search is still unclear. The purpose of this paper is to examine the effectiveness of a job-aiding tool that allows inspectors to inspect a stimulus with a natural search strategy while informing inspectors of areas that have already been searched. In general, the job-aiding tool significantly increased accuracy while decreasing search times and stopping times.
