Discovering Activities in Software Development Processes.

Software development processes are complex to monitor as they involve the coordination of manyresources working with different tools. This makes it hard to apply mining techniques for monitoringthe process. A key challenge for using traces of tools such as version control systems (VCS) is to findmeaningful abstractions in order to identify the work that was actually done. In this paper, we use datafrom VCS to analyze the actual progress of software-development processes. We develop a technique that is able to mine the activity types of which the development processes consists. We implement our technique as a prototype in Java and evaluate its outputs in terms of effectiveness. In this way, we are able to graphically uncover new behavioural patterns in real-world data from existing open-source GitHub repositories.
