Developing a Difficulty Metric for Open Source Analytic Tasks



T T. Hewett, Jean C. Scholtz


Our goal is to produce metrics for assessing the impact of software tools and environments produced for the intelligence community. To this end we need to understand the variables that make some analytic tasks harder than others and to determine which data need to be captured to meaningfully assess the effects of these variables on process and effectiveness. In this paper we describe the initial stages of development of a task difficulty questionnaire and report some feedback on the questionnaire collected from professional intelligence analysts in the context of their work. We discuss some additional steps needed to further clarify and refine the task difficulty questionnaire and explore the implications for possible task difficulty metrics.
