Abstract

From its inception, the notion of management support systems (MSS) has been closely linked to task structure, which influences both the need for management support and the ability to provide it. This article presents the results of an empirical analysis to show the relation between task structure and satisfaction with MSS. Two dimensions of task structure are distinguished: task difficulty and task variability. The results of the analysis indicate that task difficulty negatively affects satisfaction with MSS, whereas the influence of task variability is insignificant.The provision of EIS functionality generally contributes to satisfaction with an MSS. This contribution is larger when task difficulty is high; as a result provision of EIS functionality fully compensates for the negative effect of task difficulty. However, task variability may frustrate this positive influence. Overall the effort indicates that, in researching the effectiveness of MSS success, one should not only look at the information that managers would like to have but also at the possibility of providing such information. The effect of both dimensions of task structure on this ability differs: task difficulty does not lead to problems, as long as the support does not require that cause-effect relations are understood but task variability leads to numerous exceptions when data are missing or not provided timely enough. If more features are build into the system, this situation tends to get worse.
