In the philanthropic sector, measuring social impact is still perceived as a challenge. The number of projects a social investors funds, combined with their diversity often result in large time and resource investments for both the investor and the investee (or grantee). Many social investors therefore feel they do not have the means to measure more than a few outputs, like the number of participants or workshops, or the total amount of volunteer work. Although this is a good starting point, it only scratches the surface of what the project or program has established, and tells you nothing about the true impact (and value) it has created. Has the target audience really been reached? Have their circumstances been changed? Only by giving a voice to the beneficiaries will you be able to decide if the right investment choices have been made.
