I’ve heard it said that Scrum only works if you assume half of XP. I don’t have a coherent counter argument to that statement.

> Deadlines and budgets are why bad requirements happen. Almost no one is able to write good requirements, it's simply too difficult in all but the most basic cases.

Because projects get cancelled if you tell the truth. Even if there’s an uglier truth that the company is screwed if we don’t finish this project.

One boss referred to this somewhat grotesquely as “getting them pregnant.” Once started, sunk cost fallacy makes them keep dumping more money on it until they get what they need or the pain gets too high. In a lot of ways Agile is a more humane way of getting the same results without the deception. You give them a taste of things to come and keep trickling it out a bit at a time.
