A Proposal for a Model to Estimate Bugs in Maintenance Processes

Abstract

In recent years, information systems are essential to decide management for an enterprise. In the information systems of an enterprise, one management problem is that cost of maintenance processes for the information system become larger than the development process of the information system itself. As one cause of this management problem, there are many inquiries in the initial failure period after operating the information system. In general, there are many times to correspond to many inquiries because the inquiries are not able to forecasted. In previous studies, there have been some studies regarding factors that lead to the occurrence of inquiries, but these factors have not been clarified. In this paper, factors of the inquiries that occur are estimated by cluster analyzing contents data, time and the number of cases of bugs. From this estimation, a forecasting model that includes inquiries of bugs occurring is proposed. Moreover, information sheets are proposed to introduce the proposed forecasting model to the development field of information systems.
