A Dialogical, Story-Based Evaluation Tool: The Most Significant Change Technique, in American Journal of Evaluation Vol. 24 No. 2

The Most Significant Change (MSC) technique is a dialogical, story-based technique. Its primary purpose is to facilitate program improvement by focusing the direction of work towards explicitly valued directions and away from less valued directions. MSC can also make a contribution to summative evaluation through both its process and its outputs. The technique involves a form of continuous values inquiry whereby designated groups of stakeholders search for significant program outcomes and then deliberate on the value of these outcomes in a systematic and transparent manner. To date, MSC has largely been used for the evaluation of international development programs, after having been initially developed for the evaluation of a social development program in Bangladesh (Davies, 1996). This article provides an introduction to MSC and discusses its potential to add to the basket of choices for evaluating programs in developed economies. We provide an Australian case study and outline some of the strengths and weaknesses of the technique. We conclude that MSC can make an important contribution to evaluation practice. Its unusual methodology and outcomes make it ideal for use in combination with other techniques and approaches.
