Under the principles and intentions of The Royal Decree on Criteria and Procedures for Good Governance B.E. 2546 (2003) to create responsive public administration with citizens at the center of government activities, the OPDC published the New Public Management Techniques and Methods Handbook: Citizen-centered Approach to Public Administration in B.E. 2549 (2006), which has been used as an operational handbook for responding to and satisfying the needs and wants of citizens. This handbook proposes a paradigm shift in public service. Traditional public services that prioritize the input permeated with rules and regulations in order to guarantee the legitimacy, accuracy, and equitability of public services have been transformed to objective achievement, output, outcome, and value for money of public services, including service quality and customer satisfaction. The handbook describes five procedures of Citizen-centered public service which are customer and stakeholder identification, public service identification, customers’ or stakeholders’ needs and wants surveys, administrative resource identification, and public service quality improvement.
