摘要: IFPUG作为目前使用最为广泛的功能规模度量方法,不同度量员在对同一个实时系统进行度量时,结果存在较大的偏差。本文通过IFPUG和COSMIC方法对多个实际项目度量结果的比对,分析存在偏差的原因,提出IFPUG→COSMIC→待度量软件的映射关系,并对方法进行验证。结果表明,建立IFPUG→COSMIC→待度量软件的映射关系,可以提高数据功能的识别准确度,缩小不同度量员度量结果间的偏差。
Abstract: As the most widely used functional size measurement method, IFPUG still has the limitation that there is a large deviation in experimental results when different measurement members measure the same real-time system. Based on the comparison of several measurement results of multiple projects by IFPUG and COSMIC method, this paper analyzes the reasons of these deviations. And a mapping relationship of IFPUG→COSMIC→measurement software is proposed. The experiment results show that establishing the mapping relationship of IFPUG→COSMIC→measurement software can improve the recognition accuracy of the data function and narrow the deviations between different measurement results of different practitioners.
