软件开发项目经理已经知道，在一个后期的软件项目中增加人力会使它更晚。这是布鲁克斯（1975）的《人月神话》中的一句名言。管理人员还认识到，即使两个人月的工作量分配给两个开发人员，开发周期也不是一个月。然而，经理们想看看这两个开发人员何时完成两个人工月的工作量。当然，经理们并不认为开发周期从两个月缩短到一个月。如果两个开发人员的开发周期短于两个月，管理人员将决定增加新的开发人员。因此，我们提出了一个新的工作量估计模型的基础上共享作品之间的通信。该模型包括软件开发项目的UML概念模型。概念模型中的类和关系分别表示作品的类型和作品之间的关系。共享工作导致通信工作量的增加。通信工作量是从概念模型中的类之间的关系导出的。在案例研究中，我们使用该模型，我们能够定量地重新确认著名的句子“神话的人月”。
Software development project managers have already known that adding manpower to a late software project makes it later. This is a famous sentence in "Mythical man-month" written by Brooks (1975). The managers also recognize that even if two man-month workloads are assigned to two developers, the development period is not one month. However, the managers want to see when the two developers finish the two man-months workload. Of course, the managers don't think that the development period reduces from two months to one month. If the development period in the two developers is shorter than two months, the managers will decide to add the new developer to the work. Therefore, we propose a new workload estimation model based on communications among shared works. The model includes the Concept Model of UML of a software development project. The classes and relationships in the Concept Model present the kinds of works and relationships among the works, respectively. Sharing works causes increments of communication workload. The communication workload is derived from the relationships among the classes in the Concept Model. In case studies using the model, we were able to reconfirm quantitatively the famous sentence of "Mythical man-month".
