Purpose – The purpose of this paper is to clarify how IT managers' decision styles affect their evaluation of information technology. Design/methodology/approach – Four different decision styles were assessed in a leadership test directed towards IT managers. Each style included two dimensions: confidence judgment ability and decision heuristic usage. Participants belonging to each style were interviewed and their answers analysed with regard to their reasoning about central areas of IT management. Findings – Results suggest that a decision style combining intuitive and analytical capabilities lead to better evaluations of information technology. Originality/vale – The results of the present study are valuable for the understanding of how decision styles impact on IT management in everyday life
