软件成本估算一直是软件项目管理的重要部分。经过半个多世纪的研究和工业实践，成本估算方法、模型得到了极大的丰富。这些方法、模型也衍生出了各种成本估算工具。但是，成本估算方法和模型的基础是历史项目数据。没有历史项目数据的公司和组织只能利用其他公司或组织的数据来进行自己项目的成本估算。如何利用跨组织数据进行有效的成本估算成为更具现实意义的问题。针对这一问题，提出了一种有效利用跨组织数据进行成本估算的方法，并通过实验说明了方法的有效性。

Software cost estimation has been an important part of the software project management. Afterover half a century of research and industrial practice, cost estimation methods and models have been greatly enriched. A variety of cost estimation tools are derived from these methods and models. However, cost estimation methods and models are based on historical project data. Companies and organizations without historical project data can only use data from other companies or organizations to do the cost estimates of their own projects. How to effectively do cost estimationwith cross-company data becomes more realistic. Aiming at this problem, we propose a new cost estimation method to use cross-company data effectively. The experiments show that the method could improve the accuracy.
