alt Hacker NewsI think that's a myopic view. Getting something anything in the hands of your potential users that's even vaguely in the ball-park of a solution shaped thing gives you extremely valuable information both on what is actually needed and, to me more importantly, what you don't have to build at all.
I consider it a success when an entire line of work is scrapped because after initial testing the users say they wouldn't use it. Depending on the project scope that could be 6-7 figures of dev time not wasted right there.
Much of what you are saying does not apply to consumer banking.
"Build fast and break things" works in big tech, but its a serious risk in financial services.
That being said, we are being forced to "build faster and try not break things."
