In contrast to the hard factors, soft factors are very often ignored during project management. Such factors, involved with the internal services within the team, are concerned with working with people, ensuring customer satisfaction and creating a conducive environment for the project team to deliver high quality products which meeting stakeholder expectations. This research aims to investigate the intertwined effects of project team internal soft factors. Combining the exploratory factor analysis and fuzzy decision making trial and evaluation laboratory (DEMATEL) technique, an empirical case is demonstrated to show the effectiveness of the proposed method. The exploratory factor analysis is applied for extracting the dimension and criteria structure. The fuzzy DEMATEL technique is then used to analyze the intertwined effect. The proposed method has proven to be an effective one for analyzing the complex interrelation of human psychological concerns.
