This article contributes to research on evaluation by examining the capacity and contribution of developmental evaluation for innovating. This case study describes the "preformative development" of an educational program (from conceptualization to pilot implementation) and analyzes the processes of innovation within a developmental evaluation framework. Developmental evaluation enhanced innovation by (a) identifying and infusing data primarily within an "informing" process toward resolving the uncertainty associated with innovation and (b) facilitating program cocreation between the clients and the developmental evaluator. Analysis into the demands of innovation revealed the pervasiveness of uncertainty throughout development and how the rendering of evaluative data helped resolve uncertainty and propelled development forward. Developmental evaluation enabled a nonlinear, coevolutionary program development process that centered on six foci--definition, delineation, collaboration, prototyping, illumination, and reality testing. This article concludes by encouraging evaluators to understand the demands of innovation and the value of design thinking when innovating.
