Indeed this is a very major issue. The trick here is that you actually
have to plan up-front to throw away the first version. If you're
careful enough you can make the first version so useless in practice

I'm not so sure in those cases that those results are due to that same
I've not only read many case studies about, but also seen often enough
in real life, situations where management decisions lead to putting
prototypes into production even when there was no real economic need to
