Because you make in order to think.
You make things in order to get basic feedback. You don’t spend a lot of time refining your prototype. You just want to get the main idea to learn how and if it works. You have a bias toward action. Get your ideas out of your head and into the hands of the people you’re looking to serve. Use anything at our disposal, from cardboard and scissors to sophisticated digital tools.
When you don’t make something simple first you are loosing the chance to learn lessons from it.
Staying always in the realm of theory means missing the goal to get impactful solutions out into the world.
When you make your idea tangible soon you are lowering the risk of failure at the end of the process.
By making it real you are making it simple to share and learn how to make it better.
