Collective impact is described as a way to collaborate to resolve issues by sharing information that can influence change. This framework uses different stakeholders that collectively shares the same vision to impact and change an organization. Different tools and methods are used to measure and monitor activities. Collective impact I believe is very similar to program evaluations. Both approaches identify and agree to measure programs and initiatives. The Collective impact approach as well as a program evaluation, both emphasizes consistent and open communication between stakeholders to maintain a level of transparency.
