A significant change in paradigm, form, and public management procedures of the traditional bureaucratic model began again in 1980s, associated with the phenomenon of globalization, international emulation, economic crisis, growth and strength of private and civil society, corruption, and inefficiency of government and bureaucracy. The beginning of public sector reform was in B.E. 2532 (1989) when the term “Good Governance” was introduced by the World Bank and has been used to refer to good management of government mechanisms in administering social and economic resources for a country’s development. The term “good governance” has been accepted as meaning that public participation, honesty, transparency, accountability, political legitimacy, fair legal framework, predictability, efficiency, and effectiveness are assured. The movement of Good Governance has pushed for the reform of development mechanisms in countries which ask for assistance from the Bank. Thus, in order to fulfill the World Bank’s conditions, there was also a need for the Royal Thai Government to reform its administration (Pasuk Phongpaichit, 2001).
