Experiment Design Expert

Overview

Design fast, low-cost experiments to validate product hypotheses before committing to full development. This skill applies Alberto Savoia's pretotyping philosophy ("Make sure you are building The Right It before you build It right") alongside lean experimentation methods for both new and existing products.

When to Use

• You have a product idea or feature hypothesis and need to validate it cheaply.
• You want to test willingness to pay or genuine user interest, not just stated preference.
• You need to choose the right experiment method for your context (new vs. existing product).

Core Principles

1. XYZ Hypothesis Format

Every experiment starts with a falsifiable hypothesis:

"At least X% of Y will do Z."
