Impact measurement and data-driven decision making by people working for social enterprises, CSR and NGOs remains limited, both locally and globally. We have built an open-source “Community Development Index,” which is a simplified decision-making and impact analysis tool for people working in social enterprises, community organizations and the civic body. It can be used to achieve a complete cycle of social impact measurement. It comprehends the current state of development and measures the change to communities across nine different domains. We are helping local NGOs and CSRs with CDI implementation.
