第二层 (0.0125×N1 + 0.1×N2 + 0.8×N3 + 6.4×N4)0.11。项目管理者联盟
第三层, (0.00156×N1 + 0.0125×N2 + 0.1×N3 + 0.8×N4)0.11。club.mypm.net
第四层, (0.00002×N1 + 0.00156×N2 + 0.0125× N3 + 0.1×N4)0.11。training.mypm.net
显然，以第四层为例，与第三层或第四层的用例数量相比，第一层用例的数量的影响微乎其微。项目管理者联盟

本文描述了基于用例进行评估的一个框架。为了使描述更加具体，本文为框架的参数选择了一些值，尽管这些值有待于论证，但它们并不总是错误的。像往常一样，随着数据的搜集，这种估计应该根据实际情况和重新估计的参数值进行测试。这种框架对于不同种类的系统考虑了用例层次、规模和复杂度等思想，并且不再采取细粒度的功能分解。为减轻计算的负担，对于诸如 Estimate Professional 这样的工具，可以构建一个前端，从而提供一种基于用例的规模输入的不同的方法。转自项目管理者联盟
