论文摘要
这项研究旨在帮助公司领导者和管理团队为未来的软件项目提供更准确的时间和成本估算。本文着重分析项目复杂性与成本和时间超支之间的关系。大约50个项目的示例数据是从更改点数据库收集的。使用统计技术定义和测试了两个研究假设。定量分析包括描述性分析和回归建模。实验结果表明，项目复杂性与成本和时间超支之间存在牢固的正线性关系。根据研究结果，需要专注于复杂项目的计划阶段，并分配更多的时间和预算，以更准确地估算此类项目的完成日期和初始预算。
This study aims to assist Company leaders and management team in providing more accurate time and cost estimations for future software projects. This paper focuses on analyzing the relationship between project complexity and cost and time overrun. The sample data of around 50 projects are collected from the Changepoint database. The two research hypotheses were defined and tested using statistical techniques. The quantitative analysis includes descriptive analysis and regression modelling. Experimental results show a strong positive linear relationship between project complexity and cost and time overrun. Based on the study outcome, there is a need to focus on the planning phase of complex projects and allocate more time and budget to estimate the completion date and the initial budget of this type of project more accurately.
