本文提出了一种扩展的挣值管理- EVM技术，通过整合的历史成本性能数据的过程中的统计控制作为一种手段，以提高项目成本的可预测性。所提出的技术进行了评估，通过案例研究，在行业中，评估所提出的技术在22个软件开发项目的实施进行假设检验与95%的显着性水平，和所提出的技术是更准确和更精确的比传统的技术计算的成本性能指数- CPI和估计在完成- EAC。
This paper proposes an extension of the Earned Value Management - EVM technique through the integration of historical cost performance data of processes under statistical control as a means to improve the predictability of the cost of projects. The proposed technique was evaluated through a case-study in industry, which evaluated the implementation of the proposed technique in 22 software development projects Hypotheses tests with 95% significance level were performed, and the proposed technique was more accurate and more precise than the traditional technique for calculating the Cost Performance Index - CPI and Estimates at Completion - EAC.
