The Public Construction Commission was established on July 20, 1995. In order that government departments have a rule to follow, the Government Procurement Act is promulgated by presidential decree on May 27, 1998. Furthermore, its spirit was established on the Chapter I- General Principle, the Article one ¡§This Act is enacted to establish a government procurement system that has fair and open procurement procedures, promotes the efficiency and effectiveness of government procurement operation, and ensures the quality of procurement.¡¨ There are more than 40 seed laws and 10 types of operating regulations enacted by the administration, the Public Construction Commission, since the implementation of the Government Procurement Law. Hence, the Government Procurement Act tends to be more complete. However, the act is not only applied to the public departments, but also applicable to other organizations, such as public schools. It can be observable from the Act 3 ¡§Procurement conducted by any government agency, public school or government-owned enterprise (hereinafter referred to as the "entity") shall be governed by the provisions of this Act. With regard to the matters not provided for in this Act, other relevant laws shall govern.¡¨; Act4 ¡§A juridical person or organization which takes a grant from an entity shall conduct a procurement in accordance with this Act and be under supervision by the entity provided that the amount of the grant is not less than half of the procurement value and also reaches the threshold for publication.¡¨ and Act 5 ¡§An entity may entrust a juridical person or organization to conduct its procurement.¡¨ From the above, it is obvious that they should abide by the Government Procurement Act, and the purchasing behavior of organization, which takes the financial subsidy over 50% from government, also should obey the act. Therefore, regardless of whether a formal civil servant, as long as the purchasing behaviors are relevant to the government procurement, the contractor personnel must to follow the Government Procurement Law. In this study, the architecture-oriented government procurement management model (AOGPMM) is constructed which is based on six fundamental diagrams of the structure-behavior coalescence (SBC) architecture. AOGPMM represents multiple views of procurement management by integrating the structure and behavior of government procurement. So, the purchasing officers can effectively understand the whole picture of government procurement through AOGPMM. Keywords: Enterprise Architecture, Government Procurement, AOGPMM
