Thoughtback [https://thoughtback.com/] sent me a pertinent reminder this morning. No affiliation, just a great tool.

    Organizational metrics, which are not related to the code, can predict software
    failure-proneness with a precision and recall of 85 percent. This is a significantly
    higher precision than traditional metrics such as churn, complexity, or coverage 
    that have been used until now to predict failure-proneness. [1]
