The quality of architectural design mostly rested with the individual performance of architects in the past. Today, with the increasing development of technical level, the quality of a design project more than ever before entails the cooperation among different professions invovled and the teamwork of a professional team. The engineers and scholars, however, tend to disregard the errors in cross-professional communication and the unnecessary duplicate labor which cause problems for the quality of design. Based on the theory of Total Quality Management systems, the thesis suggests that a series of feasible technical standards be established within an institute of architectural design for quality control. Specifically, we adopt the PDCA cycle by dividing it into four stages: Planning of technical standards, Doing of technical standards, Checking of technical standards, and Acting of technical standards. Finally, this essay will make a conclusion and give some suggestions on technical standard-setting.
