What term refers to information given to a salesperson indicating how he or she is performing?

The correct term referring to information provided to a salesperson about their performance is feedback. Feedback is crucial in the sales process as it allows the salesperson to understand how well they are meeting customer needs, achieving sales goals, or adhering to company standards. This information can come from various sources, such as customer interactions, performance metrics, sales reports, or evaluations by managers.

Feedback plays an essential role in sales training and improvement, helping the salesperson to identify strengths and areas for development. By actively engaging with feedback, salespeople can adjust their strategies, enhance their communication skills, and ultimately, improve their overall effectiveness in selling.

In contrast, response time relates to how quickly a salesperson can address customer inquiries or complete transactions, but it doesn't specifically highlight performance in terms of effectiveness or quality. Loudness is not relevant to a salesperson's performance measurement, and adaptive selling refers to the ability to change one's sales approach based on the customer’s behavior, which is a skill rather than a measure of performance.
