Step-by-step explanation:
A good way to assess a customer's knowledge on a product is through surveys and questionnaires. By gathering information directly from the customer, you can understand their level of knowledge and identify any gaps. Another way is to observe their behavior and interactions with the product. For example, if a customer is able to navigate a software interface confidently, it shows a certain level of knowledge.
