Building a team you’ve inherited is like repairing a leaky ship in mid-ocean. You will not reach your destination if you ignore the necessary repairs, but you do not want to try to change too much too fast and sink the ship. The key is to find the right balance between stability and change. First and foremost, focus only on truly high-priority personnel changes early on. If you can make do for a while with a B-player, then do so.
