Doc Society's Impact Field Guide & Toolkit is a series of modules that guide users to develop an evaluation approach for creative projects. While it was originally designed for documentary filmmakers, the Toolkit is useful for any creative arts or journalism group to help define and measure their impact. Best of all, it includes case studies, which are so important to help make the difficult work of impact measurement more real and practical. In addition to its essential work in support of funding and elevating documentary film, Doc Society (formerly BRITDOC) has been a leader in impact measurement for years. They pioneered the idea of "Impact Producers" whose sole focus is to increase the impact of a film.
