USABILITY ASSESSMENTS FOR HYDROLOGIC FORECASTING DSS

Usability assessments were used to obtain feedback on the development of a flood forecasting decision support system. The feedback was used to guide design of system functionality, interface, training, implemen tation, and operations. The usability process was user focused and was dependent upon implementation of a prototype system in an operational setting. This paper describes concepts and methods applied to collect reflective and objective data on DSS components and information outpu ts. The general structure of the usability assessments is discussed an d results of assessments are summarized.
