The LibreOffice project has become a large software development project. Tobetter understand how it is being developed, a software development analyticsdashboard has been deployed for it. This dashboard tracks most of the publicdata about LibreOffice development, and it allows to visualize, drill down andunderstand that data. The talk will present this dashboard, and will explainhow to interpret the data it provides. The Document Foundation Development Dashboard visualizes data obtained fromsome systems used to support LibreOffice development: git, Gerrit, Bugzilla...The data is retrieved from them, stored, organized an massaged in a database,and later visualized in the dashboard. The dashboard permits to track activity(in commits, issues, pull requests, questions and answers, etc.), actors (whois creating the code, who is fixing bugs, who is answering questions), andprocesses (hot long does it take to close issues, or to accept pull requests). The Document Foundation Development Dashboard has been deployed usingGriomoireLab, an complete FOSS system for retrieving data from softwaredevelopment repositories, storing it, and producing different kinds ofanalytics, dashboards and reports.
