Title: Analysis of software bug data across version releases with application to optimal version release Authors:  Simon Wilson - Trinity College Dublin (Ireland) [presenting]

Abstract: An emerging trend in software over the last 5 years has been to maintain a schedule of frequent version releases in order to remain competitive and pass on important security updates to users as quickly as possible. While software testing is still done, software users are encouraged to report bugs to the developer. We look at some simple models for the times to bug discovery across successive versions of software. We propose various ways in which the dependence between releases can be modelled. We fit the model to data on bug discovery for the Mozilla Firefox browser. Finally we use the fitted model to suggest an optimal time between releases that trades off the costs of releasing faulty software with the opportunity costs of delaying release.
