In recent years, the concept of new public management (NPM) has gained significant attention in the field of public administration. NPM is a modern administrative doctrine that emerged in the 1980s and 1990s as a response to the perceived inefficiency of traditional models of public administration. It is an approach focused on results, aimed at improving the delivery of public services by introducing management techniques from the private sector into public sector organizations. NPM is a modern approach to public administration that emphasizes efficiency and accountability in providing public services. This concept is implemented worldwide, especially in developed countries, and has significantly influenced administrative reforms in Europe. This paper aims to explore the origins, development, and implementation of NPM as a modern administrative doctrine. The paper also highlights the fundamental principles of NPM and critically analyzes the advantages and disadvantages of the concept. Additionally, the paper provides an overview of the implementation of the new public management concept in different countries around the world. The significance of this paper lies in its contribution to the literature on contemporary administrative doctrine.
