Problem:
As the company's product manager, your boss (the marketing manager) is concerned about the future success or viability of the product line you oversee. She wants to make sure that you understand the reasons that could cause a popular product to become an unpopular product.
She asked you to meet with her and discuss, from your own experience in the marketplace, 2 manufacturing company's products that seem to have declined in popularity. This decline in consumer favorability severely hurt these other firms.
To avoid this from happening in your own firm, your boss has asked you to describe some examples of this phenomenon and your opinion on why the popularity declined.
