In my experience this leads to mediocre results. You need to throw out prototypes often, otherwise you'll end up with shitty solutions.

It's an unfortunate fact that as soon as you see a prototype, everyones instict is to fix the most glaring issues and call it done.

But to get to a truly great solution, you often have to throw out the prototype, and start all over.

Unfortunately very few people have the patience for that. Usually the prototype already took so much time, that everyone is already totally stressed, and starting over is out of the question.

If throwing the prototype away isn't possible, it's not really a prototype anymore.
