Understanding the influence of multisite evaluation requires careful consideration of cultural context. The author illustrates dimensions of influence and culture with excerpts from four National Science Foundation evaluation case studies and summarizes what influence teaches everyone about culture and what culture teaches everyone about influence. This chapter argues that raising the visibility of culture is necessary for a full and complete appreciation of evaluation influence beyond a narrow interpretation of use. Thoughtful inclusion of individual and organizational aspects of culture supports valid understanding of evaluation influence and of factors such as involvement that support influence.
