> Going "hardcore" on things can be fun, at the right time in your life, for the right reasons, with the right people.
This is a death march - no question about it. The book by Edward Yourdon should be required reading for any who are still at Twitter.
One of the things that is in the book had in it that I recall was a four quadrant grid of 'morale' and 'likelihood of success'(?).
There are indeed high morale high chance of success death marches - and they can be fun to be on. The "we will get this done and it will be glorious" type things.
There are also the low morale high chance of success that just drag on and it is a "we will get this done, and then we will all quit." I've been on that one - it was awful. I can only imagine the low morale low chance ones being completely dreadful and people hoping that it gets canceled before too much longer.
Amazon says that I got a copy of this on August 11th, 2012... and that was an order in which the book I got was given to my manager at the time. The project rolled out in October (before Black Friday code freezes went in effect) and I started looking for new employment in January after the company did its yearly bonuses.
