There are different types of assumption tests you can use to check if your ideas are right:

• Surveys or interviews: Ask potential users questions to test if they want or need your product. This helps with desirability assumptions.
• Prototypes: Create a simple version of your product to test both desirability and usability. It helps see if users are interested in the product and can use it easily.
• Landing pages: This tests desirability and viability by gauging user interest (e.g., sign-ups) and showing whether there’s enough demand for the product to be successful for the business.
• Data analysis: Look at existing data, like user behavior, sales figures, or website analytics, to see patterns. For example, if data shows users are leaving your site quickly, it might challenge your assumption about usability.
• A/B testing: This tests usability and desirability, showing which version of a product users prefer and whether they’re engaging with it as expected.
