This textbook examines public administration from a comparative perspective by incorporating theory and practice from two separate fields: Political Science and Development Administration. It explores the intricate interplay of diverse administrative frameworks, emphasising the adaptation and efficiency of governance models in varied political and cultural landscapes, especially in the selected five countries: the UK, the USA, France, Japan and India. This volume explores the evolution of comparative public administration and the approaches of F. W. Riggs, Ferrel Heady and John D. Montgomery to understand the major administrative systems around the world. It examines the extent to which the various forms of polities, regimes and public opinion can influence bureaucracies in multiple countries and analyses the role of public administration systems in their democratic frameworks. This book will be useful to students, researchers and teachers of Public Administration, Public Policy, Political Science and General Management. It will also be an invaluable companion to the policymakers in the government sector as it will strengthen their conceptual understanding of the subject.
