When General Chaovalit Yongjaiyuth was the Prime Minister of Thailand, the Master Plan of the Public Sector Reform B.C. 2540-2545 (1997-2001) was introduced to the Thai public sector. Based on the concept of “good governance”, the Plan was to strengthen the bureaucracy to be an efficient mechanism in developing economic, social, and political systems by reforming the functions and sizes of public organizations, and improving the operating systems of public organizations. The plan proposed to change the principle philosophy of governing the country from centralization to decentralization. The two principles of the plan concerned the reform of functions and size and relating to the improvement of operating systems in public organizations with the aim to develop public management and its service delivery in terms of efficiency, equity, and fairness (The National Bureaucretic Reform Committee, 1997). As a result, the Plan was the starting point of the present Thai public administration reforms.
