This document provides guidance on implementing the International Aid Transparency Initiative (IATI) standards within an organization. It discusses scoping the implementation, getting data ready, publishing to the IATI Registry, and integrating IATI into existing work processes and organizational culture. The implementation schedule should define what data will be covered, publication frequency, and which data fields will be published and when. Resources like an implementation schedule and process mapping are also recommended to support the transition to more open data practices.
