The relative
impact on project success of each planning process was calculated by using a
multivariance regression. In this analysis, all four-project success variables have been
analysed together in the same regression equation as the dependent variables. All 16
planning processes have acted as the independent variables in this analysis. The
significance level was used as the measure to evaluate the importance of a planning
process on project success. Table V ranks the impact of all 16 planning processes on
project success, sorted by their importance.
