Final answer:
Barney's Bookstore's situation, where the demand for a new title surpasses their supply, is a positive problem that reflects high customer and student demand, requiring strategies to ensure product availability.
Step-by-step explanation:
When Barney's Bookstore experiences a situation where the demand for a new title exceeds its available supply, this is an example of a positive business challenge. It reflects a high customer demand for a product, which, while indicative of the title's popularity and potential sales, also presents a logistical dilemma in ensuring that the supply can meet this demand. To address this, Barney's Bookstore might consider several strategies such as increasing its order quantity, setting up pre-order options, or even creating a waitlist for customers to ensure they eventually receive their desired product. These actions can help in managing student demand and maintaining customer satisfaction, while also capitalising on the popularity of the item.
