SPARROW DSS: Web-based Decision Support
Online - No requirements other than a web browserView and investigate modelsRun reports from modelsTest “What if” scenarios
Decision Support:• User Investigation• Scenario Testing

Decision Support for a Wide Audience
Well labeled sections help make data unambiguous
Context awareexplanatory information

Advantages of Web-BasedDecision Suppport
Reach more audiences and levels of sophisticationRemove the need for special software after the model is completedPermanent, always available archive of model in usable formUseful for modelers as well
Bottom Line: More mileage from the model

The Real Value: The Model
The report is a snapshotThe model is likely capable of predictions for scenarios beyond the scope of the report
The model offers decision support
The report gives resultsThe model allows investigation

New Paradigm Project Flow
Build Support and funding for the projectDo the project
Gather DataBuild ModelPublish report and Launch online DSS
Begin Building theDSS Tool

Plan for Decision Support Up Front
Value in Launching the DSS and report togetherDSS developers can work with modelers while they are still on the projectIncompatibilities will be uncovered and can be addressed early
