Project Maintenance

Abstract

Maintenance is a phase that is usually placed after project completion when problems start to arise. Agile development changes this approach in depth, since maintenance is always the current status of the project. In this section, after a short introduction about maintenance model, the application of these models in classical and Agile methodologies will be discussed in order to highlight differences and focus the reader on the different approaches to this activity that can cost a lot if not well realized. The last part of this section is dedicated to metrics for the estimation of maintenance effort and on metrics for the prediction of faults in order to guide the reader in this very complex environment. All of you can select the metrics that seem to be well suited for approaching the problem of effort measurement or fault proneness detection.
