Case studies

At the core of this case is a distribution, or sourcing, problem that can be modeled and solved using linear programming (LP). There are also issues of whether to build (a) new plant(s)––and if so, what the capacity should be––and whether to expand or close one or more of the existing plants. These latter issues can be analyzed using a 0/1 LP facility-location model. Alternatively, because the number of options is limited, they can be analyzed using the straight LP model of the distribution problem as a tool to facilitate analysis.

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.

Julia Brown, toy buyer for the Hightower Department Stores, has to decide which of three imported stuffed animals will be offered for sale by the 16 Hightower stores during the approaching Christmas shopping season. The case is appropriately used as an introduction to the concepts of least squares and regression analysis. A linear relationship between realized and test-market sales can be used to forecast the sales potential of the three proposed animals, and an explicit treatment of the uncertainty in this forecast is necessary in order to decide how many of each adopted animal to order.

This case describes an innovative response-modeling project at INTUIT. The case can help students understand the basics of (and the issues surrounding) response modeling, an important tactic in data-base marketing.

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.

In this case, the managers of quality assurance for a pharmaceutical company must specify a fill target for individual bottles of a new blood-pressure medicine. Higher targets lead to higher material costs but fewer seconds.

As marketers love to teach students, differentiation must be the focal point of marketing strategy. But what happens when a firm's competitive set is shared by similar customers, perceived differentiation is weak among rivals, and loyalty is a thing of the past? This was the dilemma the French luxury jeweler Mauboussin faced: how to leverage its iconic brand to access new customers, domestically and abroad, and through new channels, while preserving the image of luxury goods founded on the myth of rarity and exclusivity? The case was designed and used for the latter portion of an international MBA marketing course and would work well in most international business courses.

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.

This case concerns the promotional activities of Nashua Photo, the nation's largest mail-order photofinishing firm. Discount-price mailers (inserted in local newspapers, for example) were used to generate new customers, but also allowed existing customers to pay a lower price. Students must evaluate not only the results of last quarter's 125 separate promotions in light of this “leakage,” but also the appropriateness of discount-price mailers within Nashua's marketing mix.

“This case is an updated version of ““Netflix Inc.: DVD Wars”” (UVA-M-0763), and was written as a replacement for it.

A financial analyst is asked to appraise the value of Netflix's stock at a time of unprecedented turmoil for the company. This case introduces customer lifetime value (CLV) as a useful metric for subscription-based businesses.”
