 In the Summary of Case Studies, the report goes on to state, "The VVCRP was effective over a period of five years of sustained involvement in two major neighborhood institutions...at influencing not just individuals, but also organizational policies, practices, and culture.This level of organizational influence is impressive when the relatively modest level of VVCRP staff time and resources invested into making these changes is taken into account.The pivotal levers of change at each organization were individual leaders who were moved by the HR principles to make major changes in their own beliefs, attitudes, and behaviors, and then took the initiative to inspire, enable, and mandate similar changes within their organizations.
