It would be okay if prototypes would be prototypes, but in the software field prototypes are too often taken into production. It&#x27;s like a designer giving you a small model how they envision it. You don&#x27;t expect to shrink yourself and live in the model house out of paper. It should be the same with software. Just recall the struggle with Twitter&#x27;s MVP that failed to be available. Maybe we should differentiate between builders, designers and visionaries in the software field.
