Identify a *product (e.g., desktop PC) or product type (e.g., office supplies) or service that is sold and bought in a business-to-business environment, and assume the role of salesperson for the product.

Within the business or organization that buys the product (i.e., the prospect) identify positions or job titles that fulfill the different roles in a buying center, and support your proposal. Identify as many titles/job positions for each role as possible, doing research where necessary. If applicable, point out how some positions/job titles might play more than one role. Is there a relationship between some of the roles? Is that relationship always present?
