You should have warned me about this more convincingly!
This is why I find if you don't already have good relations with management and trust each others judgement, it really doesn't matter.
They will do as they wish, and throw you under the bus as needed.
This is protection in adversarial scenarios, but is also just a great habit In general. Verbal discussion is really good for getting people on the same page, but without notes it's very easy for details and decisions to get lost.
If you are in the kind of adversarial management relationship where this is necessary, you have already lost.
Do you think this kind of guy, when you point to "hey remember the conversation, here's the follow-up mail with the meeting notes" he's gonna be like "oh yeah, I was wrong, you are right." ?
It's good to have meeting agendas and follow up minutes, I just rarely find that they are going to help you litigate anything. More to remind you how a decision came to be.
That way, it's unavoidably in front of everyone's face, and you get the perk of ironclad timestamps in the document-editing history.
You are wrong because you were right but unable to persuade me. Not "hmm, maybe I should be more receptive to my reports feedback".
