Influence of Comprehensive Project Planning on Project Success in Rwanda. A Case of Nzove Water Supply Project (2021-2024)

The general objective of this study was to investigate the influence of comprehensive project planning on success of Nzove Water Supply Project in Rwanda.The research design was combined descriptive and correlational research design to structure the data collection, analysis processes, and data analysis was conducted using SPSS 25.The model shows a strong positive relationship between these factors and project success, with an R value of 0.858, indicating a significant linear association.The R-square value of 0.736 implies that 73.6% of the variance in project success can be explained by these factors, while the Adjusted R-Square of 0.730 provides a slight adjustment for the number of predictors.The unstandardized coefficient for Comprehensive Scope Planning is 0.579, indicating that a one-unit increase in Comprehensive Scope Planning results in a 0.579-unit increase in project success ( = 0.579, t = 8.773, P = 0.000<0.05).The unstandardized coefficient for Comprehensive Budget Planning is 0.174, indicating that a one-unit increase in Comprehensive Budget Planning results in a 0.174-unit increase in project success ( = 0.174, t = 2.384, P = 0.019<0.05).The coefficient for Comprehensive Management Planning is 0.178, indicating that a one-unit increase in Comprehensive Risk Management Planning results in a 0.178-unit increase in the success of the Nzove Water Supply Project, but it is not statistically significant ( = 0.178, t = 2.580, P = 0.011< 0.05).The study recommended that project managers ensure clear scope documentation, frequent budget assessments, and proactive risk management to enhance the Nzove Water Supply Project's success.
