This study presents an approach to harnessing the power of case studies for research evaluation called R&D value mapping (RVM). While this method uses case studies in the traditional manner to provide in-depth insights, it also structures case studies through an analytical framework that yields quantitative data and less subjective "lessons learned." When properly applied, RVM can yield an inventory of outcomes and empirical generalizations regarding the determining variables. A particular advantage of the approach is that it not only provides an indication of the type and amount (though not a single numerical index) of outcome, but also gives insight into the reasons outcomes are achieved. Thus, RVM is useful for policy management strategies seeking to replicate success. The specific steps associated with the R VM method are illustrated through studies that have applied the technique.
