This research aims at a domestic management actual situation of professional construction management. To do an integrity study first, and then takes 1996 American Customer Satisfaction Index as a model foundation. Using Partial Least Square algorithm as the analytical tool which studies structure model to construct a professional construction management causal model, the author makes the conclusion that the weight estimated by PLS and the score of Measured Variable construct a management matrix diagram and analyze a key factor of influencing professional construction management service quality to improve a service quality and promote a customer satisfaction. Thus, managers could assign resources correctly to promote customer satisfaction.

本研究首先针对国内工程专案管理实务运作现况做完整探讨，再以1996年美国顾客满意指标(American Customer Satisfaction Index；ACSI)为模型基础，利用部分最小平方演算法，作为研究结构模型的分析工具，尝试建构工程专案管理顾客满意度之因果关系结构模型，并根据PLS所估计出的权重与衡量变数的分数，建构策略管理矩阵图，分析影响工程专案管理服务品质关键因素，作为改进服务品质与提升顾客满意的基础，以利管理者正确分配资源，提升顾客满意度。
