The results indicate that there are statistically significant correlations between the use of PMTT and different project success measures in different phases of the project life cycle. In other words,PMTTthat are the contributors to project success measures are contingent upon project phases. For example, in the planning phase, cost baseline and CPM significantly contribute to the project success based on cost (S2), while the use of bottom-up estimate and bar chart is counterproductive (show a negative value with S2). The use of CPM significantly contributes to time (S1), cost (S2), and quality (S3) success
measures and the use of hierarchical schedule contributes to the customer satisfaction (S4 and S5) and overall success (S8).
