This document introduces social return on investment (SROI) as a framework for benefits management. SROI provides a standardized process to quantify social, environmental, and economic outcomes of projects, programs, or organizations. It involves identifying and valuing outcomes for stakeholders, mapping how outcomes are achieved, and calculating a ratio of benefits to costs. The document outlines when SROI is useful, principles of the approach, the six-step process, and examples of how SROI has been applied to evaluate family rehabilitation services, corporate social responsibility initiatives, and user experience audits. SROI aims to capture both financial and non-financial benefits in a rigorous yet transparent way to inform management decisions.
