In my profession, as in most if not all, everyone wants my services as fast as possible up to and including immediately. However, if I miss something or make a mistake, no one dies. I think there is a speed where those involved have come up with a plan, double checked it to make sure they didn't miss anything. Notify the team of the plan and receive their feedback, dot the i's and crossed the t's. And THEN proceed. I would imagine that those times are all over the place dependent on a myriad of variables but going any faster than that is risky. That said, if you had told me that during my waiting period I would've slapped you (figuratively of course).
