In order to insure that a decision support system meets the needs of t
he user, it is necessary to understand the environment in which the DS
S operates and the factors that make up the environment. This research
identifies specific DSS structures and their relationship with key en
vironmental factors. Five specific DSS structures were identified and
tested against ten environmental factors identified in literature as i
mpacting DSS structures. All five of the DSS structures were significa
ntly influenced by different combinations of the ten environmental fac
tors tested. A framework for DSS development is also presented.
