How you react to feedback determines if something is or isn’t a prototype

Stop splitting hairs over what is and isn’t a prototype. Just know that a prototype is an input, not an output.

Okay…but how do you know if something is an input and output? Apply this simple rule of thumb. Say you’re getting feedback about your ideas from other people. If your reaction is “great”, then it’s an input. If your reaction is “son of a bitch!”, it’s an output.

Once you no longer value feedback, you’re past the point where prototyping can help. You’re just seeking approval. You’re also not designing anymore, you’re implementing. That’s only a bad if it’s not time to implement. Figuring out the timing for that is an entirely different conversation. Stay tuned…
