or the team is doing too much at a time, and delegating different "projects" to different people in the name of efficiency.
I think that's actually wrong - the whole team should work on the "same" task. For example, coding a module could be done together. It might seem like only 1 person is writing code, and everyone else is over the shoulder looking, but you save knowledge transfer times in the future, and you save code review time (you do review at the same time when everyone is there).
