Abstract : This paper describes the user evaluation of 12 decision aids used during Prairie Warrior 94, at Fort Leavenworth, KS. Fourteen students from Command and General Staff Officer College and five data collectors participated in the study. The functions of the decision aids varied from visualization of the battlefield to exchange of information to weather analysis. An off-the-shelf generic questionnaire designed to be tailored for the needs of evaluators of decision aids was employed to rate the systems. The questionnaire was based on a multiattribute hierarchy that was based on a review of the literature to identify criteria used to assess system utility and usability. The data collectors and students rated the aids that assisted with communication as having the highest utility along the dimensions identified in the hierarchy. Differences are described that were noted between the data collectors and student assessments.
