Ahsoka and I have been in ship evacuations before, just not this kind of ship.
Everyone has an assigned lifeboat. They need to know which one so they know which one to go to. You've got people to check for anyone left behind, and that's fine, but someone needs to be in charge on each lifeboat of deciding when it launches... regardless of whether everyone's made it. If the ship's in danger of total destruction and taking the lifeboat with it, you have to be prepared to make the call to launch. Also, directing things after the actual evacuation.
