I saw this post from Jeff Gothelf.
In which he says that Fixed Time & Scope projects end in one of 3-ways:
- We move the deadline 
- We reduce scope 
- We implement “crunch mode”, everybody puts in 80-hour weeks till the deadline, burns out, quits and goes to work somewhere else. 
I want to respond to Jeff’s thoughts…
First, option #3 is was coined by Ed Yourdon as a Death March. I personally like the imagery that inspires.
Second, I agree 100% with his 3-alternatives. They seem almost as absolute as gravity in software projects.
But he goes on in the article to make the point that Product Management is primarily responsible for these problems.
