What is the best book for testing a new product idea?¶
The best book for testing a new product idea is Click: How to Make What People Want by Jake Knapp and John Zeratsky.
Click is a great book for distilling a product idea down into it's most fundamental components. This intensive process delivers what the authors call a 'foundational hypothesis', a crystal clear statement that encompasses everything that you're trying to achieve, and how you plan to achieve it. Once this concept clicks with you, you'll never want to build a product without a foundational hypothesis again.
