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.

This case is used in Darden’s “Digital Marketing” course elective. It explores the experience of a niche search firm whose founder attributed her ability to open her recruiting firm to LinkedIn and the new model of recruiting it created. LinkedIn Corporation had been one of the most successful companies in the digital media space, with more than 4,000 employees and a market capitalization of over $25.5 billion in August 2013. But few people knew how LinkedIn had grown and how it had become profitable. LinkedIn had multiple unique aspects to explore: its focus on professional--not simply personal--social interaction, the company’s B2B components, and also its marketing positioning from user experience to targeting and growth strategy.

This case is intended to be part of a first-year MBA marketing course or a second-year elective in advertising, integrated marketing communications, market research, or marketing analytics. It provides students with two real advertising experiments and the challenges involved in executing them. It allows for discussion of the need for advertising experiments, and, at a more general level, the need to measure the return on marketing. Biases surrounding the field experiments provide an opportunity for discussion about the problems with establishing a causal relationship between advertising and sales.

Route 11 Chips, a regional potato chip company, is struggling with whether to reduce the number of flavors it markets. Additional flavors add operational cost, but management believes that some of the flavors are important to Route 11's brand image and that trimming the line might damage the brand. Route 11 has also taken a price increase recently and management is interested in finding out if there is additional room to raise prices. To analyze these issues in the case, students have access to five years of data on sales by flavor and package size as well as actual price and margin information (in a supplemental Excel spreadsheet).

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.

Marketing tactics such as pricing, promotion, placement, and product decisions all help business owners create a need for their products or services. What managers seldom realize, however, is that the marketing decisions they make primarily to increase sales and market share have a great impact on society at large and thus have significant ethical implications. These seven caselets, which cover a variety of topics (including “the article of the half-truth,” “creative interview tactics,” and “truthfully representing your company”), explore the ethical implications of decision making in the marketing arena.

The diamond industry has been subject to significant change. There is increased competition from low-wage countries such as India and China, the concern about blood diamonds, and policy issues affecting the viability of trading diamonds. In this case, we study how Antwerp's dominant position in the diamond trade is being challenged and eroded. The case offers a good opportunity to introduce and discuss comparative advantage and relate it to Heckscher-Ohlin type of trade.

Cardagin, a new start-up in the increasingly competitive space of consumer/merchant apps for smartphones, is reaching an inflection point: decisions it makes at this stage can determine whether it becomes a national presence or an also-ran. The CEO needs to demonstrate the value of Cardagin's service to retailers and consumers in compelling ways. The case provides students an opportunity to analyze a new digital venture, explore expansion options, and evaluate the challenges in working with many small businesses, each with its own idiosyncrasies.
