An Empirical Study on Adjustment Factors to Estimate Maintenance Cost of Applications Developed Using Components

Abstract—Recently, the efficiency of software development is dependent on the use of component modules and open source. However, these need the additional cost and effort for understanding and modification, which is basic process in software maintenance. In this research, adjustment factor which shows the maintenance cost of the black box embedded software like the component module and open source is proposed. In order to calculate the maintenance and repair adjustment factor, we have classified type of application system based on maintenance and repair specialized company K. And the methods for determine whether the adjustment factor applicable to the application is proposed. Also it confirmed that it need to adjust maintenance cost about 8% in result of an analysis of data and the discussion with the person in charge and experts about application type in which the component is included.

Index Terms—Software maintenance, maintenance cost, cost adjustment factor, maintenance cost estimation.
