You probably got this one right. The right answer is that
this is a people mistake. And despite the fact that this is
an easy answer, I just want to make sure to stress
once more. Because this is a very classic mistake. And one that
can have dire consequences. You should never add people, to a
late project. Because in 99.9% of the cases, that's only going to make
things worse. Why? Because these people have to be brought up to
speed, and also because having more also makes the communication more difficult,
the meetings more difficult and so on. So in
short, do not add people to a late project.
