Prototypes, Not MVPs: How to Actually Learn Fast (and Lean)

You might think that building a 'minimum viable product' means coding up a bare-bones version and launching it to your entire user base. But this can be an expensive, time-consuming, and risky way to test an idea. In reality, the earliest and most effective learning happens through simple prototypes—throwaway experiments designed to test exactly one big risk at a time, without pushing half-baked code in front of customers or risking damage to brand and trust.

Smart teams treat prototypes as learning tools: a paper storyboard, a clickable but fake UI, a Wizard of Oz manual process behind the scenes, or a segment tested with live but limited traffic. These aren’t meant to impress; they’re meant to spark customer reaction. Research shows that only by seeing real user behavior and emotions can we separate good guesses from truly valuable solutions. The risk of waiting to build and launch even a simple production-quality product is lost time, wasted money, and sometimes total confusion among teams about what counts as 'done.'

Prototypes let you learn cheaply and safely, adjust course, and arrive at a solid solution rapidly. The best teams see prototyping not as a one-off, but a core, continuous discipline—changing the whole culture of product development from output to insight.

As you face your next big idea or user complaint, pause and choose to learn, not launch. Aim for the simplest, fastest representation—a crude sketch, a dummy webpage, a day-long build—that lets you directly watch real users interact. Put your ego aside as you gather their responses and let the raw truth steer your thinking. Each prototype should be easy to discard or morph, no matter who suggested the idea. Make this your new habit, and you’ll gain speed, confidence, and resilience—stopping waste and starting progress, one fast experiment at a time.
