Once the salespeople understand the relationship between sales and collection of accurate information, they can be trained to collect more accurate information. There are three elements in the collection of accurate information. The first element in the collection of accurate information is the elimination of stereotypes. Salespeople need to realize that each customer is unique and has unique needs and perceptions. Once the salesperson realises that each customer is unique, the first task of the salesperson is the collection of information on the customer' needs. This is done by developing questioning skills. Salespeople need to ask questions to uncover customer needs and perceptions. The final element in training salespeople is to improve their listening skills. As discussed earlier, listening skills make telemarketers more accurate than field salespeople.
