Introduced in GitLab 9.3.
Conversational Development Index (ConvDev) gives you an overview of your entire instance's feature usage, from idea to production. It looks at your usage in the past 30 days, averaged over the number of active users in that time period. It also provides a lead score per feature, which is calculated based on GitLab's analysis of top performing instances, based on usage ping data that GitLab has collected. Your score is compared to the lead score, expressed as a percentage. The overall index score is an average over all your feature scores.
The page also provides helpful links to articles and GitLab docs, to help you improve your scores.
Your GitLab instance's usage ping must be activated in order to use this feature. Usage ping data is aggregated on GitLab's servers for analysis. Your usage information is not sent to any other GitLab instances.
If you have just started using GitLab, it may take a few weeks for data to be collected before this feature is available.
This feature is accessible only to a system admin, at Admin area > Overview > ConvDev Index.
