Abstract
Even though planning and resource related factors is crucial in the construction project, in the construction projects at Noah Real Estate, there has been instances of delay, cost overruns and challenges to the achievement of the project objectives, which show some performance challenge in project management practice. While there have been some studies that analyze the factors that affect project success for construction projects, empirical evidence is limited in regards to the specific effect of planning and resource factors on project success in the context of Noah Real Estate. For this reason, this study was formulated to fill this empirical gap or address the identified empirical gap and to investigate the relationship between planning and resource related factors to project success and to give evidence-based recommendations for the improvement of project performance. This study aimed to explore the effect of planning and resource factors on project success. The main aim of the research was to investigate the link between planning practices and the successful implementation of projects in terms of resources. The research used was quantitative research method, and the data obtained in this study was the data of respondents who were 102 respondents used in the data collection process. Data collected was converted and analyzed using SPSS software with descriptive, Pearson correlation, multiple regression and ANOVA analysis. The results of the correlation analysis revealed that both planning and resource factors have positive and statistically significant relationships with project success. Planning was moderately positively correlated with project success (r = 0.521, p < 0.01), so that better practices in planning are related to increased project success. Likewise, resource factors showed a moderate positive correlation with project success (r = 0.467, p < 0.01), implying that improved resource management is conducive to project success. The result of regression analysis revealed that the model explained 28% of the variations in project success (R² = 0.280, Adjusted R² = 0.265) which shows that the variables used in the model has a moderate ability to explain the variations in project success and this result is acceptable for construction sectors. The ANOVA result also shows that the overall model is statistically significant (F = 19.222, p < 0.001), which indicates that the planning and resource factors together significantly affect project success. The planning had positive and statistically significant influence on the success of the project (B = 0.496, p = 0.005) according to the coefficient’s analysis. This translates to better planning resulting in improved project success. However, the effect of resource factors was positive but not statistically significant (B = 0.133, p = 0.297), meaning that the resources contribute positively to the project success, but do not have a strong direct impact on project success when planning is part of the model. This underlines the fact that, project success is more about planning than resource availability. The findings indicate that planning factors have a significant positive influence on project success, whereas resource factors show a positive but statistically insignificant relationship with project success. This suggests that effective planning plays a more influential role in enhancing project success within the study context. Therefore, organizations should strengthen project planning practices while ensuring the efficient utilization of resources. Integrating effective planning with sound resource management can contribute to improved project performance.
