From Ask for Advice, Not Permission
The problem with permission is that you are implicitly asking someone else to take some responsibility for your decision. You aren’t inviting them to participate in its success — permission is hardly seen as a value adding behavior — but if it goes wrong you might end up involving them in the failure: “Hey, I asked that team and they said it was fine.
and
Advice, on the other hand, is easy. “Hey, I was thinking about doing X, what advice would you give me on that?” In this instance you are showing a lot of respect to the person you are asking but not saddling them with responsibility because the decision is still on you.
Its a great read. Whats interesting though is what happens when it goes wrong. From HN
“…and when someone asks for your permission (probably because you’re in the person’s management chain), one response could be: “you don’t need my permission, if you think it is a good idea after getting input, go for it. If it turns out to be a bad idea, share your learnings so we don’t repeat the same mistake.””
