Lesson 6: Product Design and Prototyping
Every product you use — your phone, shoes, backpack, water bottle — was designed by a team of engineers and designers who went through hundreds of prototypes before the product reached you. Let's look at that process.
Key Concepts
User-Centered Design
Great products are designed for the user, not for the engineer. User-centered design starts by deeply understanding who will use the product, what problems they have, and what would make their life better. Only then do you start designing.
Rapid Prototyping
The goal of a prototype is to test an idea as quickly and cheaply as possible. Paper sketches, cardboard models, and 3D prints are all prototypes. Fail fast and cheap — not slow and expensive.
Iteration
Almost no product gets it right on the first try. The iPhone went through thousands of internal prototypes before release. Real products are the result of hundreds of small improvements. Each version is better because it was informed by testing the previous one.
