Though you’ve been getting feedback from the people you’re designing for all along, a Live Prototype is one of the most powerful ways to test your solution in the marketplace. Until now, your prototypes have been rough, and they’ve done only enough to convey the idea you wanted to test. A Live Prototype, however, gives you a chance to stress test your solution in real-world conditions. It can run from a few days to a few weeks, and is a chance to learn how your solution works in practice. Live Prototypes are all about understanding the feasibility and viability of your idea.
