Abstract

Software maintenance through extreme programming approach requires a dedicated algorithmic cost estimation process due to lack of algorithmic approaches for estimating cost, size and duration in agile methodology. Existing approaches of software maintenance estimation such as ACT, FP and COCOMO 2.0 reuse model are based on traditional methods of software development. Software Maintenance Effort Estimation Model (SMEEM) is an estimation method that incorporates various value adjustment factors affecting the estimation of the maintenance project [2]. The SMEEM model generates the more realistic and precise estimation results for agile and extreme programming based maintenance environment. The SMEEM Model calculates and adjusts size of maintenance effort but it is unable to estimate phase wise effort, which is crucial to determine the accurate estimates. In this paper, effort estimation technique is proposed for maintenance project that estimates phase wise effort. This technique employs empirical data from industry practitioners and PG students for phase effort estimation. The proposed technique is illustrated and validated using a case study in subsequent section. It provides more realistic result as compare to the existing techniques on maintenance effort estimation and helpful in estimating phase wise maintenance effort in extreme programming based maintenance environment.
