what is the recommended approach instead of simply asking potential customers whether they would buy the product or service? creating advertising tests to attract potential customers. relying on feedback from friends and family. conducting surveys with open - ended questions. asking \why\ questions to understand the reasoning behind their decisions.
Answer
Brief Explanations:
Asking "why" questions delves deeper into customer - decision - making processes compared to a simple yes/no purchase question. Advertising tests focus on promotion, feedback from friends and family is not from potential customers directly, and open - ended surveys may not specifically target the reasoning behind purchase decisions as effectively as "why" questions.
Answer:
Asking "why" questions to understand the reasoning behind their decisions.
