摘要
本研究调查了加纳大阿克拉地区四个主要基础设施项目的成本超支和进度延迟。该研究收集了201名项目员工和经理的数据。采用SPSS v. 25软件进行典型相关分析。研究结果揭示了成本和进度变量之间复杂且违反直觉的关系。研究发现成本与进度变量之间存在很强的负相关关系,而成本超支对进度绩效有积极影响。研究还证明了成本差异和进度差异之间的负相关关系。这一违反直觉的发现指出了一种“危机驱动的加速”现象,即面临成本超支的高知名度项目会吸引额外的资源和注意力,以在成本不断上升的情况下保持按计划进行。本研究在三个重要方面推进了三重约束理论:揭示了挑战传统假设的成本和进度变量之间复杂的非线性关系;引入“语境约束优先化”的概念作为理论的延伸;并推进了检验约束关系的方法学方法。这些贡献增强了我们对三重约束理论在发展中经济体背景下如何应用的理解,并为该领域的进一步理论发展奠定了基础。这项研究弥合了抽象理论原则和实际现实之间的差距,有助于对项目约束的更有力和更相关的理解。
Infrastructure project cost overrun and schedule delay in Ghana: Is it an issue of resource misallocation or financial constraints?
This study investigates the cost overrun and schedule delay of four major infrastructure projects in the Greater Accra Region of Ghana. The study collected data from 201 project staff and managers. The study adopted canonical correlation analysis using SPSS v. 25. The findings revealed a complex and counterintuitive relationship between cost and schedule variables. The study found a strong negative correlation between cost and schedule variables, whereas cost overruns positively influence schedule performance. The study also documented a negative correlation between cost variance and schedule variance. The counterintuitive findings point to a phenomenon of “crisis-driven acceleration”, where high-visibility projects facing cost overruns attract additional resources and attention to maintain schedule adherence despite mounting costs. This study advances the Triple Constraint Theory in three significant ways: revealing complex, non-linear relationships between cost and schedule variables that challenge conventional assumptions; introducing the concept of “contextual constraint prioritisation” as an extension to the theory; and advancing methodological approaches to examining constraint relationships. These contributions enhance our understanding of how the Triple Constraint Theory applies in developing-economy contexts and provide a foundation for further theoretical development in this area. This study bridges the gap between abstract theoretical principles and practical realities, contributing to a more robust and contextually relevant understanding of project constraints.
