Problem:
Suppose you are the brand manager for Do-the-Wild-Thing, an unscented deodorant shampoo aimed at Generation-X members. Sales of your product have been declining. Exploratory research suggests your brand is not price competitive. Outline a research plan that would provide you with the information you need to decide what to do. Explain why you selected certain methods and not other ones.
