Constance is partnering with Frank, 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 Frank's expertise because she thinks it'll 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, Frank will also provide the client organization with assistance on its applications and system design. Refer to Scenario 18.3. What type of compensation system does Constance have for her personal selling efforts? Team-based compensation plan Straight salary compensation plan Combination compensation plan Straight commission compensation plan Profit-sharing compensation plan
