In a roll-out that we want speed and safety, I feel it is important to note that the team may have bumps and will need to retool. If you want it perfect, you won't get fast. If you want it fast, you won't get perfect. The trick is for them to respond quickly and not have chronic failures. If they don't, then beat them up. If you want them to go slower and with tighter controls, then, that is likely something to feed up the channel. If you want them to go faster, with individuals responsible for understanding that their may be queuing challenges, then, tell them that. (or, let them do it, knowing that they have multiple million critics and they are people working hard todo their best)
