CoRaven: model-based design of a cognitive tool for real-time intelligence monitoring and analysis

Describes a model-based design method to develop CoRaven, a decision support tool that is intended to assist military intelligence analysts in managing and interpreting large quantities of battlefield information. In this method, we use observations of practitioners solving specific tasks in order to understand and model how they use information. We use this model of the task to help identify user needs that the tool must support, and, during initial prototyping, to guide usability analyses. We have found task models to be an important consideration in the decision support tool design process that can help to constrain the design space and reduce the time required to develop an effective decision support tool prototype
