Test the riskiest part first.

Direct answer

Lean startup is a method of running small experiments to learn quickly. You build a minimum version, measure how customers respond and learn whether to persevere or pivot. It reduces waste by testing assumptions early.

The loop

  1. Build the smallest test.
  2. Measure what people do.
  3. Learn and decide.

Example

Instead of building an app, create a landing page and see how many people sign up for the waiting list.

Key ideas

  • Validated learning.
  • Minimum viable product.
  • Pivot or persevere.
