Sarah Miller Beebe began thinking about a book of cases during her career as an analyst and manager in the U.S. Government. A variety of broadening experiences, including an assignment as Director for Russia on the National Security Council staff and a position as a national counterintelligence officer at the then National Counterintelligence Executive, drove home the need for rigorous and effective approaches to intelligence analysis. It became apparent to her that cases could not only teach important analytic lessons surrounding historical events but also give analysts experience using a question-based thinking approach underpinned by practical techniques to improve their analyses. Now, as owner of Ascendant Analytics, she helps organizations apply such techniques against their specific analytic problems.
