Estimation of Application Maintenance cost using COCOMO81
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 7
Abstract
Constructive Cost Model is one of the CE models which contribute three different models namely basic, intermediate and detailed model. Maintenance of software is very much important so as to increase the functionality of software and decrease the cost incurred in extracting new system. The first level of COCOMO is Basic which is good for quick, early, rough order of magnitude estimates of software costs, but its accuracy is limited due to its lack of factors to account for difference in project attributes. In the Intermediate COCOMO takes these Cost Drivers into account and Detailed COCOMO additionally accounts for the influence of individual project phases. Here, in this paper, we mainly estimate maintenance cost of software using basic and intermediate model by maintaining Annual change traffic and thousand source lines of code as constant. We examine these values by varying on each case, thereby obtaining the final maintenance costs in man-months.
