Security Sector Reform (SSR) is a broad and ambitious notion that concerns establishing and improving those security relationships and architectures most commonly associated with liberal democracy. Starting from the premise that there is no universally applicable model for SSR, this volume explores the question how best to evaluate SSR in European context and analyses the conditions for determining and confirming criteria of success in this regard. The systematic gathering, analysing and evaluating of international expertise in democratic control, management and reform of the security sector is one of the main functions of the Geneva Centre of the Democratic Control of Armed Forces (DCAF).
