[摘 要]：COSMIC方法作为当今主流功能规模度量方法之一，在软件功能点的划分上更加灵活具体，对软件内部结构和实现依赖更小，因而该方法在商业应用软件和实时软件有极好的适用性。但由于COSMIC度量手册中仅对功能用户、功能过程等关键因素进行了定义，没有给出具体的识别方法，加上度量过程中存在较大的主观性，导致度量结果存在一定的偏差。本文在遵循功能用户原有定义和规则基础之上，结合案例分析功能用户识别过程，提出一种有效的识别方法和步骤。

Abstract：COSMIC method as one of today's mainstream function scale measurement method, On the division of software function point more flexible concrete, To rely on a smaller internal structure and the software realization, So this method in commercial application and implementation of software has excellent applicability. But as a result of COSMIC measures only to the user, the function in the manual process and other key factors are defined, Gave no specific identification method, combined with the larger subjectivity in measurement process, cause there are certain deviation measurement. Based on the following function based on user defined and original rules, The user identification process combining with case analysis, this paper puts forward a kind of effective identification methods and steps.
Key words：COSMIC method, Function of the user, Recognition method
