First ideas for visualization consisted of visualizing the data in version control system (SVN). There are lots of tools like SVNStat [23], which make it possible to visualize the events in the version control system. So, the SVNStat tool was used to generate the graphs. However, the graphs were not useful as the problems of the project seemed not to be source code dependent. So, the research direction was changed towards the issues in Jira, because Jira was used extensively and because the tasks contain a lot of useful metadata. The metrics on lead times seemed to indicate that the team had longer sprint cycle than the aforementioned 4 weeks. This had to be investigated further.
