You can commit to an investment with no idea, at all, whether it will cost more than the benefit it delivers. I suppose "not an option" isn't quite the right wording. It's an option.
That's not what it means. You have to be diligent in asking properly and vetting the rules for what's to be done. It may also include gate meeting type things and regular status reporting. You just don't downshift the project into high torque when some phony date rises up.
I don't remember if it's "Mythical Man Month" or Thomas deMarco where I'd read it. They're better at explaining it than I.
