Core Idea

Mastering Business Testing is a structured methodology for reducing uncertainty in business ideas through experimentation, evidence gathering, and iterative learning.

Key Principle

A business model is a collection of assumptions until it is validated with evidence.

Testing Cycle

1. Hypothesis
2. Experiment
3. Evidence
4. Insight
5. Action

Goal

Move from high uncertainty to lower uncertainty by systematically testing the most critical assumptions first.

Four Risk Categories

• Desirability — Do customers want it?
• Feasibility — Can we build it?
• Viability — Can it make money?
• Adaptability — Is the timing right?

Key Insight

Progress is measured by reducing risk, not by completing tasks or building features.
