摘要

本文利用欧姆龙公司从1992年到1994年执行的36个实际项目的软件度量，统计分析了评审与软件质量以及评审与生产力之间的关系。首先，通过考察每个项目的评审工作量与现场质量(交付后的故障数量)之间的关系，以及评审中发现的故障数量与每个项目的现场质量之间的关系，我们得出:(1)更大的评审工作量有助于提高现场质量(减少交付后的故障数量);(2)在提高现场质量方面，源代码审查比设计审查更有效;(3)如果总设计和编程工作的10%以上用于评审，则可以获得相当稳定的现场质量。我们注意到，对于高达20%的审查率，在生产率(LOC/员工月)方面没有认识到相关影响。作为上面分析的结果，我们建议15%的评审工作作为我们软件项目管理的指导方针是合适的。

Analysis of review's effectiveness based on software metrics

The paper statistically analyzes the relationship between review and software quality and the relationship between review and productivity, utilizing software metrics on 36 actual projects executed in the OMRON Corporation from 1992 to 1994. Firstly, by examining the relationship between review effort and field quality (the number of faults after delivery) of each project, and the relationship between the number of faults detected in review and field quality of each project, we reasoned that: (1) greater review effort helps to increase field quality (decrease the number of faults after delivery); (2) source code review is more effective in order to increase field quality than design review; (3) if more than 10% of total design and programming effort is spent on review, one can achieve a quite stable field quality. We noticed that no relevant effects were recognized in productivity (LOC/staff month) with respect to a review rate of up to 20%. As a result of the analysis above, we recommended that 15% of review effort is a suitable percentage to use as a guideline for our software project management.
