Not enough one-on-one time with the coders. As a coder, it's very easy in a stand-up for any coder to say "yeah yeah yeah, I've got this covered". Then a week before release everyone realizes that person has a month's worth of work ahead of them. I've been all three: the "yeah yeah" guy, the manager, and one of the other coders that has to take the slack. It's a situation that seems easily avoidable just by a little better teamwork. Oftentimes "yeah yeah" can just mean "I have no idea what I'm doing", but dev2 (or mgr) could do and teach that task in half an hour, but dev1 just doesn't know who to ask.
