"The International Development Working Group brought together development practitioners and investors to explore the ways in which the changing landscape of development is creating new opportunities for effective partnerships to drive improvement in social outcomes. The Working Group assessed how impact investment can help to further drive economic development and improvement on social issues in developing countries. Working Group members agree that there is an opportunity for impact investment, in conjunction with public, private and philanthropic capital, to bring greater effectiveness, innovation, accountability and scale to address some of the world's toughest challenges. The group presents in this report its key recommendations on some proposed joint initiatives to advance the impact investing market for the benefit of the world's poor populations."

"This new report, Measuring Impact, aligns with existing best practices, and includes seven practical guidelines for good impact measurement, as well as five case studies of impact investment organisations that have successfully put these guidelines to use. In writing the report, the Working Group went through a six-month consultative and research process, which included a review of over 60 industry publications and 45 interviews with experts and practitioners in impact measurement."

"The following document presents five case studies to demonstrate how a diverse group of organizations have developed sound impact measurement practices, including how the seven guidelines are being applied in the organization, as well as the organization’s impact measurement practices, the contextual factors that shaped their impact measurement approach, how they involved key stakeholders along the way, and key “impact measurement lessons.” These case studies – which are highly diverse in nature – aim to help investors and investees translate the seven guidelines for impact measurement into an impact measurement approach that is right for them."
