Case studies

Greg Mills describes his search for the perfect engagement ring which includes an analysis of the prices of 6,000 diamonds. An engineer, Greg hopes to impress Sarah Staggers by using regression to find an underpriced diamond. Students are asked to either select one of the 6,000 diamonds or provide point forecasts for prices of 3,142 diamonds in a hold-out sample. The instructor can use the actual prices of the held-out diamonds to evaluate student pricing models.

This case was designed to build expertise in conflict management and assertiveness by allowing students to practice saying what needs to be said in challenging situations. Grounded in the pedagogy of experiential learning, the case consists of three role-play scenarios that exemplify three challenging business situations. In each scenario, two individuals are faced with a possible difference in perspective or goals. The role-play requires students to assume the role of one of the individuals, and each scenario requires another student to initiate the discussion.

An angel/venture capitalist could invest in an Internet sheet-music publishing start-up. The chance of success multiplied by the value, if successful, suggests that this isn't a good investment. Nevertheless, several friends suggest the optionality present in the venture: abort an unsuccessful website and sell the technology; switch the technology if the website is good, expand, buyout. Decision trees and Monte Carlo simulations are used to value these options, which make the opportunity look very attractive.

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.

The president of a well-established manufacturer of mattresses has asked his assistant to recommend whether to consolidate plants of three different locations. He must decide not only which criteria are most useful in making such a decision, but also how to weigh the different criteria in coming up with a single decision.

Sparta Glass Products has been losing significant market share over the last several quarters in the non-glare-glass market, with a price 10% above the competition. Lowering the price is under consideration. Unfortunately, fully allocated costs are such that the lower price results in a loss. Issues to be discussed and analyses to be conducted include the relevant costs for the decision and the reactions from competitors.

Can the return of its founding CEO turn a lagging Starbucks around? Howard Shultz must map a strategy that addresses the company's decreasing sales and perhaps too rapid growth. Had the previous CEO's efforts to streamline operations compromised the Starbucks experience or was a changing economy to blame? Schultz considers whether to close existing stores, slow U.S. growth while expanding overseas, and improve the customer experience, which he believed had eroded the company's value proposition.

“Suitable for MBA, Executive MBA, GEMBA, and executive education programs, this case uses CEMEX, a global cement producer based in Mexico, to set the stage for unfolding an analysis of a growth through acquisition strategy. It offers a discussion about the firm's overall strategy to acquire on a global scale instead of growing organically and provides an opportunity to introduce basic financial, marketing, and operational terms that can be explored in subsequent classes. The material includes a PMI process that further allows discussion on that technique.

The case opens with a conference call and another barrage of questions for CEO Lorenzo Zambrano about his bid to buy the Australia-based Rinker Group in October 2006. Until this point, CEMEX has had a long-standing habit of buying businesses in emerging markets; this acquisition would be a departure from that strategy. If the deal goes through, it would be the single largest acquisition in CEMEX's history, and it would be among its few forays into a developed market other than the neighboring United States. The company has grown exponentially and successfully. Why would this effort be any different? Was the acquisition a good idea or not? And if it was, how would Zambrano and his leadership team convince Wall Street and others of that?”

Students at all levels explore the psychology of entrepreneurship and new product branding and marketing as a young IBM executive decides whether to become an entrepreneur. He must evaluate his business plan; seek advisors; and decide how much money it will take to get started. His product idea? On-the-go water for dogs. With market research complete and a team of advisors assembled, he must decide whether to take the plunge.

John Hume, a veteran game farmer and founder of the Mauricedale Game Ranch in South Africa, was deeply troubled by the record upsurge in black rhino poaching incidents and black-market horn thefts in 2010 and 2011. While the endangered black rhino represented only one segment of Mauricedale's hunting and farming businesses in 2011, the animal's survival was an important component of the ranch's and industry's growth potential in the future. As both a businessman and a rhino advocate, John Hume was contemplating an innovative idea that might help stop the decline of the black rhino: the creation of a market for legalized black rhino hunting. As he pondered the possibilities and alternatives to determine what his next move should be, Hume had several questions on his mind: Was the legalization of the international sale and trade of rhino horns a viable solution? Was it Hume's responsibility to save the black rhino, and was the animal a good investment?
