Quantitative data analysis techniques in this study use multiple linear regression models with hypothesis testing, F test and t test which are processed with SPSS software. The results of the F test of this study prove that the TQM variables include manager's commitment, training, and continuous improvement jointly influence the project performance and for the t test results show continuous training and improvement have a positive and significant influence on project performance, but for commitment managers have no influence on project performance.
