Metrics that track shipping speed
The metrics in insights are currently all focused on the workflows and jobs that Circle runs.
Metrics that help me track my team's shipping speed would add a ton of value. Metrics could include:
Time to review: the time it takes for a GitHub PR to be reviewed after it is opened
Time to prod: the time it takes from when a branch is started to when the branch is merged to master and gets deployed
Number of review cycles: stats about the number of rejections a PR gets
There are lots of interesting stats here that would bring me back to the Circle dashboard even when I'm not trying to figure out why my build broke.
