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
- Build the smallest test.
- Measure what people do.
- 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.
