"The Guide to SROI provides a clear framework for anyone interested in measuring, managing and accounting for social value or social impact. This Guide was originally written in 2009 by the UK Cabinet Office. Updated in 2012, it is the result of consultation with practitioners, members, academics and others with an interest in social and environmental value and impact measurement."

"Acumen and Unilever have partnered to bring a gender lens to impact measurement with a new toolkit designed to better understand how programs and services are affecting women and girls across the globe. Created with Acumen's Lean Data team, the toolkit, A Lean Data How-to Guide: Understanding Gender Impact, delves into the work of five different programs within Acumen's portfolio and Unilever's initiatives to develop a new, highly effective framework that entrepreneurs, impact investors, corporations, donors and philanthropists can use to measure their impact on women and girls."
