This document discusses best practices for corporate social investment (CSI) and measuring the impact and return of CSI programs. It defines key aspects of best practice CSI, including formal strategies, management involvement, stakeholder engagement, and impact assessment. The document notes common reasons why CSI programs fail, such as a lack of professionalism and understanding of local contexts. It emphasizes the importance of viewing CSI as an investment rather than just giving, and measuring the impact and return through frameworks like a program logic model and impact value chain. The goal is to demonstrate CSI program effectiveness, value, and contribution to community sustainability and business benefits like reputation and talent recruitment.
