Estimating Software Maintenance Cost by Varying Maintainability Metric

C.V.S.R Syavasya


The main aim of software maintenance is keeping the availability of test systems. In this paper, we estimate software maintenance costs by applying release level model to obtain values from previous projects and find out software maintenance costs of current project. We come across three parameters namely: understandability, modifiability, testability. Maintainability metric is varied under a specified range to find maintenance costs. After deriving the final metric values, we derive the final costs of maintainability. Finally the results are formulated into three cases, where in each case provides how maintenance cost is varied by varying maintainability metric.


Understandability, Modifiability, Testability, Annual Change Traffic, SLOC
