This study aimed to examine the effectiveness of project scheduling techniques on project performance, using a machine rebuild project at Kalumbila as a case study. The research was guided by three objectives: To establish the effectiveness of project scheduling strategies on project performance, to determine the relationship between project scheduling techniques and project completion, and to investigate the challenges faced by project managers in adopting and implementing advanced scheduling methodologies. A quantitative research design was employed, targeting a population of 50 individuals comprising 10 top management, 10 middle management, and 30 low management employees at Kalumbila. A probability sampling design was utilized to ensure a representative sample. Data was collected using structured questionnaires and analysed using SPSS. Baseline schedules are deemed essential by 55% for achieving project goals. In relation to project cost management, 47.5% find modern scheduling techniques outperform traditional methods, while 100% agree that optimized resource allocation accelerates project completion. Stakeholder communication and collaboration have a moderate to significant impact on project completion rates, according to 55% and 45% of respondents, respectively. Best practices for successful implementation include strong leadership support (55%) and comprehensive training (35%). Overall, the study underscores the importance of agile methodologies, predictive analytics, and effective stakeholder engagement in optimizing project scheduling. However, it highlights the need to address challenges such as resource constraints, budget limitations, and regulatory impacts to improve scheduling practices.
