I suggest at our retro that other teams have skills in languages and frameworks that we have only just started using, and that we practically just make it up as we go along and then keep making changes as we realise things suck. Why not bring a real expert in from another team for 1 or 2 days to rapidly improve our knowledge?

15 people in the room, every single one of them: "no that's stupid. Why would you even do that?"

Really? Am I the retarded one?
