Understanding the customer's pain points and what they attempted in the past that was unsuccessful is a way to determine if a customer might be a valid prospect for the product. This helps to identify the customer's needs, challenges, goals, and motivations, as well as to assess their fit and readiness for the product. This also helps to position the product as a solution that can address their pain points and provide value. Reference: https://www.salesforce.com/resources/articles/sales-process/#qualify
