"The report examines the impact measurement approaches of 13 GIIN members (including development finance institutions (DFIs), fund managers, banks, and foundations) who invest directly into healthcare delivery companies- detailing the metrics, methodologies, and assumptions that are commonly used by these investors, as well as the challenges and limitations they face.

The report aims to bring greater transparency to the diversity and limitations of current impact measurement approaches, facilitate shared learning, and provide a tangible resource for those who are new to the sector or seeking to improve practice."

"This handbook provides investors, businesses and private sector development practitioners with an overview of tools and methods for effective and appropriately tailored data collection for impact measurement and management. It builds on the recognition that the methods of larger, independent impact evaluations of, for example, government-funded programmes rarely lend themselves well to a private sector context. In reviewing select private sector-relevant tools and methods, it draws out how such tools can deliver impact insights while often feeding valuable business intelligence back into companies."

"Impact assessment is a key component of managing an impact investment portfolio, and many investors today are building methodologies that bring value
beyond simply reporting outcomes.

For many investors, the impact goal is the common thread across a portfolio of various sector, geography and instrument types and this diversification can make choosing an impact assessment methodology challenging. As such, the process for developing a methodology is often an iterative one, refined with experience and data over time.

To help inform that iterative process, this research presents sixty-eight case studies from twenty-one leading impact investors that share best practice and
debated viewpoints on impact assessment along the investment process."

"Impact due diligence creates value for a broad range of stakeholders across the impact investing ecosystem, including impact investors, investees and the field at large. Key benefits include fostering internal alignment around intended impacts and priorities, deepening understanding of investees’ activities, supporting the construction of more positively impactful portfolios, improving investor and investees’ ability to communicate impact, strengthening relationships between investees and investors, and increasing firms’ ability to attract additional capital. In combination, the benefits of widespread adoption of impact due diligence should attract additional capital to the field and thereby foster the formation of more inclusive and sustainable financial markets."Impact Due Diligence: Emerging Best Practices" is the first of two reports intended to elevate the practice of impact due diligence."

"The Handbook on Impact Evaluation serves two broad audiences – researchers new to the evaluation field and policy makers involved in implementing development programs worldwide. We hope this book will offer an up-to-date compendium that serves the needs of both audiences, by presenting a detailed analysis of the quantitative research underlying recent program evaluations and case studies that reflect the hands-on experience and challenges of researchers and program officials in implementing such methods."

"Over the last six months, Nesta has been working with the Impact Management Project to explore how we think about evidence of impact. This document provides guidance on both using existing evidence of impact, and building your own evidence base."

Written by ANDE's Director of Research and Impact, this article gives an overview of why to measure impact, what to measure, how to collect data, and practical considerations for putting impact data into practice.

"The Global Value Exchange (GVE) is an online platform developed by Social Value UK that allows users to set up their own projects, start to monitor the social value they are creating, and helps them to manage and maximise their social value."

"A consistent approach to impact calculations allows companies, investors, policymakers, multi-lateral institutions, non-government organizations, and other sector stakeholders to estimate the impacts created by off-grid solar in a consistent, clear, and coherent manner. The metrics help build the evidence base for the many benefits that off-grid solar lighting and high-performing appliances unlock for people previously living in energy poverty."

"The guide provides investors with a basic overview of social metrics for impact investing, an outline of the issues and challenges of social impact measurement, a summary of existing social impact measurement tools and a description of how they are being used, and a set of diagnostic tools to help investors think through key questions and issues related to measurement."
