Case studies

This case describes the coal-procurement process of a small electric utility. The manager of the production fuel department must decide how much coal to purchase from each vendor and how to allocate the purchased coal among the utility's three coal-burning plants. The situation can be modeled and solved as a linear program. Sensitivity analysis can be used to help formulate a strategy for negotiating with the vendors and to address other special issues.

Whole Foods and Wild Oats were both natural- and organic-food stores that competed for similar customers on values such as high-quality and healthy products, excellent customer service, knowledge of products, and an enjoyable shopping experience. In February 2007, Whole Foods announced that it would purchase a smaller but formidable competitor, Wild Oats. There was tremendous geographic complementarity involved: The merger would give Whole Foods the largest footprint within the natural- and organic-grocery industry in North America.

Is “Fair Trade” really fair? This case examines the concept, history, and logistics of the Fair Trade movement, specifically for coffee. Fair Trade began as an attempt to ensure farmers received fair compensation for their crops and credit when needed. Fair Trade also provided opportunities to help coffee growers learn best practices and sustainable farming methods (minimal damage to the environment, for example). But Fair Trade had its critics, who claimed that ultimately the farmers did not benefit and that retailers charged more for Fair Trade products and pocketed the difference. This case examines these issues through the eyes of one coffee-drinker who has specifically chosen her caffeine venue because of the Fair Trade designation.

Madison Kryswada, director of alumni relationships at State University, assembled a 123-school data set to explore, in her words, “the drivers of alumni giving rate. ” The alumni giving rate contributed 5% to the increasingly important U.S. News & World Report rankings of U.S. colleges and universities. Wanting to understand the relationship between this variable and school characteristics, Kryswada gave her assistant a list of four well-formed questions to answer.

George Lasiter sells special-events T-shirts and must decide how many to order for an upcoming concert. He has high, medium, and low estimates of both concert attendance and the percentage of attendees who will want a shirt. In addition, he has assessed the relative likelihoods of each estimate. The case can be used to introduce or reinforce the fundamental issues surrounding decision making under uncertainty.

A product manager at Apple examines the past, present, and future of the PC industry in September 2011 in the wake of Steve Jobs's resignation and HP's announcement that it was exiting the PC industry in favor of enterprise software solutions and consulting. The protagonist thinks through current forces in the PC industry, including market share trends, mobile computing, ultrabooks, and cloud computing services—as well as the position of the Mac in Apple's product portfolio—and is faced with making a decision about the future of the Mac.

In September 2015, VW had admitted to United States regulators that it had deliberately installed “defeat devices” in many of its diesel cars, which enabled the cars to cheat on federal and state emissions tests, making them able to pass the tests and hit ambitious mileage and performance targets while actually emitting up to 40 times more hazardous gases into the atmosphere than legally allowed. The discovery had prompted the U.S. Environmental Protection Agency (EPA) to halt final certification of VW’s 2016 diesel models, and VW itself had halted sales of its 2015 models. As fallout from the defeat devices developed, VW posted its first quarterly loss in more than 15 years, and its stock plummeted. Top executives were replaced, and VW abandoned its goal of becoming the world’s largest automaker. Stakeholders around the world had been asking since the scandal broke: “How could this have happened at Volkswagen?”

This case and its companion, “Myerson Industries” (UVA-QA-0299), constitute the materials for a negotiating exercise. The exercise is a distributive-bargaining situation surrounding the negotiation of the price for the construction of a building (some minor opportunities exist for creating mutual value).

Filtroil had opened a new factory that was a merger between Shenzhen Filtroil and its supplier, Liu Li—whose own factory was on the verge of bankruptcy. But the supplier had begun making excessive demands and threatening to delay product shipment to the United States if his conditions were left unmet. The case reveals the options that could be taken to manage the situation. The case is suitable for use in organizational behavior, human resource management, and strategy classes at the MBA and executive education levels.

A credit-card company must value portfolios of customers based on their future earnings. The payment characteristics of customers serve to classify them into states. This case can be the basis for discussing state dynamics over time in a Markov process.
