Assessing Human Factors Requirements in the Test and Evaluation Stage of Systems Development. Volume I

摘要

The methodology employed in the development of a model for human factors evaluation incorporated in system testing is given. The report outlines an initial attack upon the problem of determining when, where, and how human factors inputs should be provided during the planning and development cycle of Naval Systems, with particular emphasis being given to measuring the consequences of such inputs in terms of systems effectiveness. All work was directed toward the Test and Evaluation (T and E) phase of system development in order to develop measures of effectiveness capable of being applied to a specific system undergoing T and E by the Operational Test and Evaluation Force (OPTEVFOR). By using this technique two advantages result: first, it is possible for human factors specialists to give specific estimates of the change in systems effectiveness induced by attending to or overlooking a number of human considerations; second, the procedure allows systematic accumulation of reference data by which the cost-effectiveness of human factors programs can be contrasted with that of other 'software' or even hardware changes.
