Ever find yourself looking for the perfect case for an exam or mid-term? They can be quite rare. "Green Ox" was written specifically for a mid-term exam in an MBA Marketing Management class. Rather than focus on one particular concept or issue (e.g., segmentation, product line depth), the case challenges students to develop a marketing strategy for a food and beverage manufacturer's new line of sports beverages that contain beneficial antioxidants. Focal decisions include choosing a segmentation scheme(s), choosing a specific target segment(s), and articulating a positioning statement(s) for the new product - in light of market trends, customer information, and competitor positions. Students must also make recommendations regarding the product name, number of products in the line, and the price (including a break-even analysis). Distribution and promotion issues are downplayed, yet there is sufficient information to determine whether students' recommendations on the larger issues account for the necessary integration of the 4Ps.
