In some big companied many core corporate teams which hate that level of transparency and build their own opaque systems. I've seen this for departments like IT, HR, legal, etc.
I'd rather have tickets for everything and full transparency except for confidential info.
Im a huge believer in transparency. But I also understand why, in a big company, people don’t like it. It’s very easy for metrics to be weaponised by political players who are out for themselves.
