Ask HN: Who broke it? (DevOps Change Management)

Our company is getting bigger and we find it harder to stay aprised of changes (infrastructure, code, database structure, server config) across the firm that would impact the production environment. This hurts the most when we identify and try to fix newly discovered bugs. It’s hard to know what chsnges across the teams may have caused it.

What are some good approaches/tools one can use for tracking these production changes?
