Lean Startup Methodology emphasizes the importance of quickly testing assumptions and gathering feedback to validate or invalidate ideas before investing significant time and resources.

The key steps in this framework include:

1. Formulate a hypothesis: Clearly define your idea or assumption that you want to test.

2. Build a minimum viable product (MVP): Create a basic version of your product or service that focuses on delivering the core value or functionality.

3. Measure: Define relevant metrics to evaluate the success or failure of your idea. Collect data and analyze the results.

4. Learn: Gather insights from the data and customer feedback. Determine if the hypothesis was validated or invalidated.

5. Iterate: Based on what you've learned, make necessary adjustments and improvements to your idea or MVP.

6. Pivot or persevere: Decide whether to change your direction (pivot) or continue refining and scaling your idea (persevere).
