The Government Procurement Act has been officially implemented on May 27, 1999. Article 108 of this Act stated that ”The central, municipal, and county (city) governments shall each establish procurement control unit(s) to monitor and supervise procurement affairs”. However, most local government procurement supervision units are currently operated by part-time commissaries. This article tries to assess the most important risk issues in order to save efforts to raise the quality of the supervision. This study is based on the analysis of previous literature and expert interviews to adhibit those supervising elements of the ”Enterprise Risk Management-Integrated Framework” which announced by COSO Committee to the supervising environment for local government. Through the risk perception by members of the supervision committee, and by means of the Analytic Hierarchy Process (AHP) to understand the perception of risk for the procurement supervision personnel of local government. In addition, further to propose the suggestion of risk response as the reference to the competence authority. The results of this study concluded the following suggestions: (1) Government should assist the procurement personnel of each unit in acquiring advanced professional qualification or increasing the number of training sessions. (2) Strengthen the supervision and review on the phase of exercising contract in the supervision report. (3) There should be standardized the effective supervising procedures. Furthermore, we have some specific suggestions for future implementation: first, the supervision report should be categorized on a basis of procurement categories in detail; second, the supervision personnel should acquire advanced professional procurement personnel qualification.
