Prototyping & Testing

📋 What it is

A prototype is an early, rough version you build to test an idea before making the real thing.

🗣️ Coach says

You don’t build the final version first — you build a cheap rough one (a prototype) to test the idea fast. Test it, find the weak spots, and improve. Better to fail on a paper model than a real bridge.

🧠 Memory hook

Build rough, test fast, improve. A prototype is a question you can hold.

😂 Giggle

How does the moon cut its hair?
Eclipse it!

😲 Whoa!

Car companies crash-test dozens of prototypes on purpose — it’s far cheaper (and safer) to break a test model than to learn the flaw on the road.

✅ Quick check: Why build a rough prototype instead of the finished product first?

Say your answer out loud first — then reveal.

🧪 Try it! (2 minutes)

Build a paper prototype of something (a bookmark, a phone stand). Test it once, then improve one thing.

🤸 Brain break: Rough-draft: mime quickly sketching, testing with a poke, then “tweaking” — fast and loose.
