OECD evidence shows that, despite the existence of many open government initiatives at national and subnational government levels, a coherent and structured approach is often lacking, even though it is important to ensure a cultural shift and to enable a strategic use of open government initiatives. Therefore, the OECD Recommendation on Open Government advises adherents “to develop, adopt and implement open government strategies and initiatives.” According to the Recommendation, “an open government strategy is a document that defines the open government agenda of the central government and/or of any of its subnational levels, as well as that of a single public institution or thematic area, and that includes key open government initiatives, together with short, medium and long-term goals and indicators.”
