"your approach on that last call was off-target. you were emphasizing low acquisition cost, while the prospect seemed more interested in durability and minimizing the need for regular maintenance," critiqued robin's sales manager after the two of them left a sales call they had made together. robin is receiving feedback.

The correct answer would be, Diagnostic Feedback.

Explanation:

When you are working in Sales department, it is very important to maintain a close and controlled relation with the customers and try to make them feel ease the way they like. All of your efforts are continuously evaluated by the you supervisor or manager. So in this case, the manager told Robin that when he was on call with the client, he was emphasizing more on the low cost of acquiring the material from their company, where as the client was more interested in durability and minimizing the need of regular maintenance of the product which he wants to purchase. So Robin should have considered his this concern, rather than telling him about the low cost of acquisition. So the manager gave Robin a detailed diagnostic feedback in which he told where he was lacking and what he needs to learn about picking up the customer's requirement.
