Prototype and Test Improvements

A prototype is a rough first version of a design — built quickly, tested honestly, and improved on purpose. Real engineers never trust a first draft. They build, test, learn, and rebuild. In this lesson you will plan a prototype, test it fairly, record what happens, and iterate. The goal is not a perfect first try; the goal is to fail forward — to learn something useful from every attempt.

What this lesson teaches

1Build a low-fidelity prototype of a design idea before committing to a final build
2Plan a fair test that changes only one variable at a time
3Record observations using a baseline and clear data tables
4Iterate on the design by keeping what worked and fixing what failed
