Fixed time, variable scope.

I want you to consider instead the possibility that Waterfall came to exist, and continues to exist, for the convenience of managers: those who need you to promise them something specific, and then deliver exactly what you promised them, when you promised you’d deliver it.

You’re a janitor: You do as much of the dirty work as possible so everyone else doesn’t have to (so the team operates more efficiently)

The Ship It stage ends when the product is available to all users.

Problem 1: Meeting efficiency - Having every team present their updates also wasn't going to work.

Ownership: I can give you a problem statement, but you’re the one who determines what your job is. You don’t get driven around by the team; you figure out what the team needs, and you deliver that.

Features work as a management control because they manifest in the final product, and their relationship to programmer-hours is about as close to linear as you’re going to get.
