Building and Supporting Open Source Communities Through Metrics
summary
CHAOSS defines more than 70 measurable metrics and ships analysis tools like Grimoire Lab, Augur and hosted dashboards such as cauldron.io. Examples: WordPress tracks 128 WordCamps, 4,379 meetups and 39,625 tickets to show global reach; CNCF reports linear contributor growth; Drupal shows falling individual contributors while company counts hold. Techniques include cohort/inactivity analysis to find likely leavers, targeted surveys to measure burnout, and a Community Safety metric model for code-of-conduct, leadership diversity and psychological-safety signals, all with GDPR/privacy and years (six+) of data-cleaning work.
