The report describes the development of a System Analysis Model SAM utilizing equipment characteristics and maintenance environments of Air Force equipments, which provides a guide for technical writers in the selection of the most efficient fault isolation presentations for current and R and D systems. From this model, three characteristics which affect the efficiency of fault isolation presentation formats were selected for experimental manipulation and evaluation. These characteristics 1 type of circuitry, 2 type of indicators, and 3 system complexity were used to evaluate the relative efficiency, in terms of performance accuracy and time, of three fault isolation presentation formats 1 standard schematics, 2 data flow diagrams, and 3 proceduralized instructions. Their nonsignificant differences suggest that the criterion for choosing between standard schematics and data flow diagrams would be the cost of development when dealing with equipments with similar characteristics. Significantly, proceduralized instructions were found to be more efficient than the other two formats. Author
