Standardized project management (SPM) is regarded as a well-structured system for improving the success of new product development projects. SPM can be defined as a standardized set of project management practices. It helps achieve the company's strategic goal through the effective use of project-driven approach. This paper used a Decision Making Trial and Evaluation Laboratory (DEMATEL) method to help companies to create a critical Standardized Project Management system and identify the influence of dimensions and criteria in the SPM system. First of all the dimensions and criteria of the SPM system are determined. DEMATEL approach is then applied to construct the SPM system structure model with Fuzzy number influence interrelationship among dimensions and associated criteria. An empirical case from industry is used to explore the effectiveness of the proposal approach.
