As a part of the operational decision aid program of the Office of Naval Research, one of the decision aids a strike timing aid developed to date was tested to evaluate comparatively the merit, if any, of the full aid and its various components. The aid was developed to be representative of a class of operational decision aids which provide trend output information. Flight experienced and flight inexperienced subjects solved hard and easy strike launch time problems using the full aid, selected portions of the aid, and without the aid. The results were analyzed by a variety of methods and supported contentions favoring the value of the aid. The results suggested 1 an increase in decision validity by a factor of five, when unaided decisions were compared with aided decisions, 2 a quite strong achievement by the aid of its goals, and 3 differential effectiveness as a function of problem difficulty and the experience of the users. Implications for aid development and evaluations of such aids are also presented.
