The goal of this paper is to produce an evaluation of IT-based support of human decision capabilities, as seen by the decision makers themselves. Recent research efforts, conducted in communication with actual decision makers in business and public administration, have been directed at the evaluation of potential of information technologies (IT) in supporting high-level information activities and creation of new knowledge for the participants. Author’s research experience shows that, apart from preference for simple support tools and techniques, there is a preference for tools and techniques that hold their efficiency over time in related situations, and are oriented towards more stimulation than automation. Also, a hypothesis is made that decision makers prefer more variety and flexibility in information sources than in decision models and other forms of “frozen knowledge”.
