A classification of success factors for decision support systems

Abstract

Whilst considerable experience in the design and development of decision support systems (DSS) has been accumulated, the expected benefits from these systems are often not realized. To help correct this deficiency the knowledge about the factors for success in consultant-led DSS development has been structured within a classification that has been motivated by three major considerations: the needed alignment between the DSS and the business requirements; the wide range of actors who play a role, both in the development of the DSS and in its continued used; and the two phases to DSS development whereby an appropriate environment for development is ensured and the commitment of the major actors is maintained as the required DSS is evolved. Field research was carried out to develop and validate the classification. The implementation of 39 DSS was reviewed in 27 organizations that together were using 22 DSS generators. 131 factors were verified in the field research as impacting on the successful implementation of DSS. A second field research investigated the importance of these factors in one specific situation, and demonstrated the use of the classification in providing guidance to practitioners operating in similar contexts.
