Abstract

This paper presents a development productivity model for Information System (IS) adaptive/perfective maintenance process. The modelling approach is from economic perspective. The productivity model considers the economic value of the maintenance activity, pre-committed fixed cost and variable cost consumed in adaptive/perfective maintenance. Factors that influence the productivity are analysed using simulation. The simulation provides a tool for IS project managers to tune the project parameters to obtain the optimal productivity in adaptive/perfective maintenance.
