I have been in this situation many times and just pressing developers is not going to work. In some rare cases adding more resources can help but usually only cutting scope and/or moving the deadline helps. Parkinson's law explains the meetings and pointless processes at the start; the first months it seems like there is a lot of time and there is no hurry to do anything. Then the actual underestimating (or overestimating as it may be) of it all will make the mess that you find yourselves in. If the management doesn't accept reality, you should find another job, because the team will break eventually as you can only do so many death marches.
