I think this is something I would schedule to use, which is probably the opposite of the intent here. The worst thing is when a team member reaches out ad-hoc and says “oh hey, do you all have a few minutes to look at X?” The answer is likely “no” for most parts of the day. I have a calendar—book time on it and I will probably accept it. If it’s not on there, it doesn’t exist and I am working on other stuff.
