Based on the Critical Success Factors theory, this study explored the influence of human-related (i.e., IT project management credentials) and project management action factors (i.e., integrated project management system implementation) on IT project management. Using data from IT project managers residing in the United States, results of independent samples t-test indicated that integrated project management implementation and IT project management success were significantly higher among certified IT project managers compared to non-certified IT project managers. MANOVA results indicated that the level of integrated project management implementation and IT project management success was significantly higher among IT project managers who have management and those with a combination of STEM and management backgrounds, as well as those who have been in the IT project management field for 5 years or more. Lastly, regression results indicated that integrated project management implementation significantly predicted IT project management success.
