OPM is an independent research organisation and consultancy. In June 2013 they produced this report Giving Together to judge the effectiveness of Islington Giving. The charity is a ground-breaking campaign that tackles the most pressing issues facing residents in Islington, London. At the heart of the project is one simple idea: that the whole can be more than the sum of its parts. The campaign seeks to establish whether a combination of partnership, collaboration, local focus and local knowledge can achieve greater impact than a disparate collection of organisations working in isolation on their own particular priorities.
