- Project is an activity that produces a unique deliverable that is bound by certain constraints in terms of cost, time and scope. This research was conducted at a company in Indonesia that is engaged in EPC (Engineering, Procurement & Construction) where the products produced are pharmaceutical, cosmetic and food industrial equipment through the process of project management stages. In its implementation, there are project completion times that are not according to the specified schedule and financing that exceeds the initial plan. This study aims to determine the effect of project maturity level on project planning, project implementation, project monitoring and control, and to determine the effect of project planning, project implementation, project monitoring and control on project performance in industrial machinery manufacturing projects, both pharmaceutical, cosmetic and food. The research data was collected through a questionnaire involving 100 respondents, namely employees of PT. XYZ with 23 questions. Data analysis in this study used the PLS-SEM approach. The results of this study show that the project maturity level has a positive and significant influence on project planning, project implementation, project monitoring and control. Project planning, project implementation, project monitoring and control factors have a positive and significant impact on project performance.
