Context and Expertise: The Case of Electronic Troubleshooting.
Flesher, Jeffrey W.
Electronic troubleshooting expertise was explored in the three contexts (design, production, and repair) that reflect distinct problem solving task environments. The purpose of the effort was to provide a more precise definition of the boundaries of expertise in electronics troubleshooting and the relationship of context to the development of troubleshooting instruction. Actual troubleshooting performance was studied in contextually representative tasks. Two subjects (engineers and technicians) were selected from each of the following areas: (1) design engineering; (2) production testing; and (3) customer service or field service. Troubleshooting on an aircraft electrical system simulator board with design, production, or normal wear flaws was studied. Beyond knowing where to start in the process, actual troubleshooting process differences were few. Generally, all subjects were able to perform in a manner consistent with their expertise, and there appeared to be little overall difference in the ability of the troubleshooters to generate and evaluate hypotheses, acquire and interpret information, or select an appropriate problem space beyond the contextual reference. Difficulties were generally overcome through self-correction and continued data gathering. Subjects from all groups were able to demonstrate high levels of skill on these problems that were representative of typical job contexts. Implications for instruction in troubleshooting are explored. Five figures and five tables illustrate the discussion. (Author/SLD)
