Final answer:
Lean Startup focuses on validating business and product assumptions through actual user data, using a fast, iterative Build-Measure-Learn cycle. It's not the best method for all development types and not limited to only startups.
Step-by-step explanation:
Lean Startup methodology focuses on creating a startup or developing products by validating assumptions through a Build-Measure-Learn cycle. This iterative process relies heavily on collecting and analyzing actual data which users generate with the product, instead of relying solely on the product creators' intuition or 'gut feelings.' The goal is to learn from users fast and adapt the product accordingly to reduce time to market and the likelihood of failure.
Reflecting on the statements provided:
- C. It relies on actual data rather than gut feelings to validate assumptions or ideas - this is a core tenet of the Lean Startup approach, as it emphasizes validating hypotheses with data gleaned from real-world experiences with the product.
- D. It is based on going through the Build-Measure-Learn cycle as fast as you can - this accurately captures the essence of the Lean Startup method, where speed and agility are key to learning and iteration.
Conversely, A. It is the best method to use for all kinds of development, and B. It is a concept applicable to startup companies only are not universally true. Different situations and types of development may require different methodologies, and Lean Startup principles are applied in various contexts beyond just startups.
