Product Thinking & Guidelines

Overview

Anyone can build. Few build the right thing. This chapter is about the muscle of product thinking — the ability to find problems worth solving, design solutions people actually want, and ship them without endless polish.

What you'll learn

• How to spot real problems vs. imagined ones (and the Mom Test that filters lies).
• Design fundamentals: hierarchy, spacing, typography, contrast — the 5 rules that fix 90% of ugly UI.
• Why MVPs are about testing hypotheses, not minimizing features.
• Shipping discipline: the 70% rule, the pre-flight checklist, when to ignore feedback.
