| Abstract: | Despite the large number of empirical investigations of DSS on decision outcomes, very few studies have incorporated longitudinal designs to assess DSS effectiveness. This study proposes that effects of DSS on decision outcomes develop over time. The study evaluated whether improvements in decision quality typically associated with DSS were due primarily to "development" or "reliance" effects. Using an add-on and take-away design, the authors examined whether introduction of DSS contributes to decision quality after controlling for task familiarity. |
