This document summarizes the shift in art museums from object-centered exhibitions designed by curators to visitor-centered exhibitions developed by interdisciplinary teams. It outlines the new process of incorporating visitor research, testing, and evaluation at every stage of developing exhibitions. This approach has led to exhibitions that more successfully communicate key messages, increase visitor engagement and satisfaction, and achieve learning outcomes. However, resistance from curatorial staff and the need for more planning time are ongoing challenges to implementing this new model.
