The Metric System about Software Maintenance

In order to solve the metric veracity in software maintenance organization, a metric system is used in this paper. By summarizing the necessity to study the metric about software maintenance, we compared the metric which is used in maintenance organizations frequently. An equation is used to measure the workload, a good many of factors are described in the equation. Then we analyzed the use about scale metric and metric model, discussed the complexity metric in detail. In the end, a metric system about software maintenance is set up, which summarized several quantitative indexes. The metric in this system is adopted in software maintenance organizations frequently and is proved that they can be used to solve the problems in organization's quantity management.
