Two multivariate statistical methods were used for hypothesis testing. First, Analysis of Variance (ANOVA), T-test and a post hoc test using Tukey’s honestly significant difference (HSD) were used to test whether or not there are statistically significant differences in the use of PMTT across phases. If it is found that the uses of PMTT are not significantly different across phases, pursuing the hypothesis testing is irrelevant. Once it was found that the uses of PMTT were significant across phases, Stepwise regression analyses were performed to test the hypothesis. The dependent variables were the project
success measures. The independent variables were the frequency uses of PMTT in each phase. Project phases were the moderating variables.
