OECD Public Governance Reviews examine governance and public management issues from a comprehensive perspective, helping countries to identify how reforms can better reinforce each other in support of overall government objectives. They also examine reform strategies that have worked in other countries and provide advice as to which reforms can be appropriately adapted to a given country. Since the restoration of independence in 1991, Estonia has met the challenge of establishing a fully functional, stable, and modern state. This review looks at how, building on its significant accomplishments to date, the Estonian public administration can work together as a single government to improve and sustain service delivery to citizens and to meet new challenges on the horizon.
