Leadership programs are often asked the question, “leadership to what end?” In other words, is the purpose of a leadership strategy to help individuals be better leaders in general or is it a strategy for achieving a community benefit, like helping to reduce the number of young people smoking or to increase the number of children staying in school? There are some interesting examples of leadership programs that are evaluating the contributions of their programs to these larger social purposes, but unfortunately they are the exception. However, there has been a significant body of research about collaborations that are having a measurable impact on community changes, like school improvements. For example, the White House Council on Community Solutions supported research by Bridgespan on what can be learned from community collaboratives that achieved a 10% plus improvement on indicators. OMG Center for Collaborative Learning conducted research on investments made by the Bill and Melinda Gates Foundation to improve postsecondary education systems and The California Endowment has sponsored a number of studies of their investment in the Building Healthy Communities Initiatives. This research can help leadership programs learn about the collaborative capacities they could develop to increase the likelihood that their participants will contribute successfully to the larger social purpose the programs seeks to advance.
