douglas: "we should encourage 360-degree feedback, mostly concentrating on subordinates, as they would be the right people to judge their superiors."
tom: "we should definitely use 360-degree feedback, mostly from external customers, as they are the ones who matter in the end."

(a) the salespeople of the company travel extensively and are expected to work independently without supervision.
(b) the salespeople of the company do not have any flexibility in the selling price of the product.
(c) the company targets a niche market segment with a limited customer base.
