The validation experiments are designed to confirm the feasibility and practicality of a business idea by providing strong evidence. The validation experiments can be categorized into: - Interaction Prototypes - Call to Action Prototypes - Simulation Prototypes Examples of Interaction Prototypes include [[clickable prototype|clickable prototypes]], [[single-feature MVP]] and [[Concierge]]. Call to Action experiments include a [[simple landing page]], [[crowdfunding]], [[presale]], and [[validation survey]]. [[Wizard of Oz]], [[Mock Sale]] are examples of simulation experiments.   Each experiment type serves a different purpose in validating a business idea. For instance, Interaction Prototypes like [[clickable prototype|clickable prototypes]] and [[single-feature MVP|single feature MVPs]] are used to test product concepts and core promises, while Call to Action experiments like [[presale|presales]] and [[crowdfunding]] gauge customer interest and willingness to pay. Simulation experiments such as [[Wizard of Oz]] and [[Mock Sale]] simulate business operations to gather evidence on feasibility and viability.   The key lesson is that validation experiments provide concrete evidence to support decision-making in the business execution phase, ensuring that the business idea is likely to succeed.
