The Effectiveness of Project Management Information Systems (PMIS) on Cost Control: A Case Study of Selected Large- Scle Construction Projects in Lusaka

Abstract

This study investigated the effectiveness of Project Management Information Systems (PMIS) on cost control within selected large-scale construction projects in Lusaka. The research was guided by four main objectives: to assess the current implementation status of PMIS, evaluate the relationship between PMIS utilization and project cost performance, analyze factors influencing PMIS effectiveness in cost control, and examine the challenges and opportunities in PMIS implementation. The study employed a mixed-methods approach involving 154 respondents from largescale construction projects in Lusaka, achieving a response rate of 95.7%. The quantitative data were analyzed using descriptive and inferential statistics, including multiple regression analysis performed with SPSS version 27. The qualitative data were examined through both thematic and narrative analyses. The study revealed that effective PMIS implementation led to a 25% reduction in cost overruns and 35% improvement in budget tracking accuracy. The regression analysis demonstrated that system quality emerged as the most significant factor (β = 0.412, p < 0.001), followed by user training (β = 0.328, p < 0.001) and implementation support (β = 0.304, p < 0.001). Technical integration challenges and insufficient training were identified as major barriers to effective PMIS implementation, with 65% of respondents citing integration issues as a primary concern. This study contributes to the existing body of knowledge by providing empirical evidence of PMIS effectiveness in cost control within the context of developing economies, particularly in Zambia. The research validates the applicability of the Technology Acceptance Model and Information Systems Success Model in understanding PMIS implementation success factors in construction projects. Therefore, the findings provide valuable insights for construction project managers, organizations, and policymakers in optimizing PMIS implementation for improved cost control.
