AIDSPLAN is a DSS resource that allows health care workers in Great Britain to plan resources for HIV/AIDS-related services better. The system explicitly encourages decision makers to focus on “what-if” questions so they can creatively experiment with strategies that might prove useful in meeting the needs of this increasing care-needing group. The DSS can be used to explore the consequences of alternative strategies or investments in resources, as well as the sensitivity of those consequences to particular assumptions about uncontrollable and unpredictable factors. This, in turn, allows decision makers to examine the impacts of the decisions in terms of likely overload, need for further resources, and of flexibility to meet future uncertainties.
