The purpose of this study is to understand the characteristics of Follower's Personal Mastery in the construction industry where followers are the givers of ideas and knowledge. We recognize the construction industry as one of the project-based organizations, has stiff competition criteria and the need for innovation in a short time span, so this research is very important because innovation results from the exchange of ideas and knowledge between leaders and followers ( Nahapiet & Ghoshal, 1998) through the Leader-member Exchange (LMX) mechanism (Dewanto, 2013). Leaders are known to have comprehensive general knowledge, while followers are known to have deep specialized knowledge (Hobday, 2000; Dewanto, 2013). The higher the Follower's Personal Mastery level, the higher the quality of the exchange of ideas and knowledge that is exchanged between followers and leaders. We chose research conducted in a construction State-Owned Enterprise (BUMN) in Indonesia which has many branches throughout the region, so that it is able to represent the construction industry. This study involved all 121 projects spread across Indonesia that existed at the time of data collection. The analytical method used in this research is descriptive statistical analysis, and the participation rate is 97.52 percent. The findings show that Follower’s Personal Mastery Variables has a high level with a mean of 4.56, especially In-Process Behavior 4.77 and Output Behavior 4.73.
