15分ルール

問題解決に躓いたときは、まず15分間自分で考えること。15分で解決しなかったら助けを求めなければならない。前者を怠ると人の時間を無駄にし、後者を怠ると自分の時間を無駄にする。

I often tell new team members about the 15 min rule (I didn't come up with it): when you're stuck on something (e.g. getting a script to run), you have to try to solve the problem all by yourself for 15 min, but then when the 15 minutes are up you have to ask for help. Failure to do the former wastes people's time, failure to ask for help wastes your time.
