One sign I see if a healthy workplace is one that tracks bugs and QA issues downstream against the same unit of work.
You quickly get a sense for what teams and even individuals are introducing the most bugs and issues.
If you can close tickets fast and your bug rate is low: that’s key, but I have found often that the people introducing the most bugs and issues into the codebase that others have to spend time dealing with are those that seemingly close their tickets rapidly every sprint
What managers care about this at all?
