Constance is partnering with Archie, an engineer, to try and sell a new aerospace product. Constance has the sales expertise, but the firm believes that the product is so high-tech that an engineer who helped design the product is needed to explain more of the technical details for clients who have questions. Constance is very eager to make sales. Normally, Constance likes to work alone, but she appreciates Archie's expertise because she thinks his advice on product characteristics and applications will help increase sales significantly. Constance is paid by the sale, so her compensation depends entirely upon her sales during a given period. In addition to answering specific questions about the product, Archie will also provide the client organization with assistance on its applications and system design. Refer to Scenario 17.3. Suppose Constance is paid a fixed salary plus a sizable commission based on sales volume. What type of compensation system does Constance have for her personal selling efforts? Combination compensation plan Team-based compensation plan Profit-sharing compensation plan Straight commission compensation plan Straight salary compensation plan
