摘　　要：为保证软件项目进度估计结果的有效性,提高项目成功率,研究了一种定量的、系统的软件项目进度验证方法.该方法结合大量的实际项目数据。通过建模,构筑了一种进度验证指南;通过显著性检验,发现回归效果不显著,说明该指南只能用于进度验证,而不能用于进度安排;通过实际案例,对进度验证指南的使用进行探讨.另外,除了对单个项目的估计结果进行有效性验证外,还以组织历史数据的收集和分析为基础,通过构建模型对组织整体进度估计方法的有效性进行了研究,实际应用数据表明,该模型能够保证和提高进度估计结果及方法的有效性,并实现持续改进.To ensure the validity of software project schedule estimation and improve the success rate of software projects, combined with some actual project cases, a quantitative and systemic method of software project schedule validation was studied. A schedule verifying guide was established by modeling. The regression result was found not obvious by validation. It indicates that this guide could only be used to verify, but not used to arrange the schedule. The usage of the schedule verifying guide was studied combined with some actual project cases. In addition to the validity validation of single project, the whole schedule estimation method validity of the organization was studied by modeling based on the collection and statistics of historical data. The actual data indicates that the model can improve and ensure the validity of the schedule estimation result and the estimation method, and can obtain continuous improvements.
