This document describes the approach taken by the OpenDRI team to design and enact impactful and sustainable projects with our partner organizations and communities. It is organized into a series of nine principles, the first 5 of which guide our thinking about how risk information should be created, managed, and used. The final 4 principles shape our relationships with other actors involved in OpenDRI work. Following a short description of the principle, we also provide examples from past OpenDRI projects and suggestions for relevant resources.
