Quick Guide

Name the test, set a due date, and list the person responsible.
Describe the hypothesis that you want to test.

Benefits

Supports communication in the team to perform test.
Helps you identify the hypothesis that are critical for your concept.

Provides documentation

Helpful Tips

Design a series of tests for critical hypothesis.
Start with cheap and quick tests. Do not design the test to be too long (concentrate in what is essential).
If the first test invalidates your initial hypothesis, go back and rethink your idea.
