Case studies

This case examines the opportunity for the Quaker-Tropicana-Gatorade (QTG) division of PepsiCo to invest in either or both of two small but fast-growing retail channels: the Dollar Channel and the Natural Foods Channel. The case gives an overview of PepsiCo's business strategy, focusing on health, wellness, and diversity and also provides a wide range of information. Students are challenged to take a broad, general management view in developing their recommendations.

The airline passenger industry in India was a mess in 2013, but the low-cost carrier IndiGo was making money. This relatively new company had managed to work against the odds and grab market share from longer-established flyers. Still, the weak rupee, depreciated by 15%, was sending a chill wind through the aviation sector, and growth plans would have to include opening new destinations. This meant hiring more employees, opening more ticketing stations, and increasing costs. Could the airline continue its climb, or would it be prudent to prepare for a hard landing?

Republic Electric is faced with the need to engage in a systematic process of evaluating vendors for its just-in-time manufacturing. The case gives students the opportunity to think through the process for vendor selection in the context of real-world constraints for a specific organization, to become acquainted with the Delphi technique for developing consensus, to gain hands-on experience with linear averaging, to engage in calculations of value indexes, and to recognize the marketing implications of effectively evaluating vendors. A key takeaway for students is the fact that vendor selection decisions are multifaceted and will vary among organizations depending on each organization’s particular strategic needs, operational constraints, and human judgment.

The case is based upon a consulting assignment with the company that is represented by Republic Electric. The experience was gained first-hand by one of the authors.

This case is targeted at undergraduate students in marketing, materials management, supply chain management, and purchasing, but can work well in a variety of business courses in which supply chains or the development of evaluation tools is studied, to include graduate classes.

The concept of vendor assessment is well developed in the literature and represents a pragmatic, but often neglected, step in the practice of choosing suppliers.

This case explores the decision of a fast-growing company to expand its distribution network. Financial information is provided in it so students can understand the basic distribution network design covering inbound transportation, outbound transportation, distribution-center operations, and inventory.

Alan Silko must decide whether to invest in seven statistical-process-control (SPC) stations in order to increase his chances of becoming a “select supplier” for a large computer company. The student must do a discounted-cash-flow/decision-tree analysis of the option. The student is also given the opportunity to construct x-bar and range charts and to do an SPC analysis.

This case is used in Darden's Supply-Chain Operations elective. The field-based case gives supply-chain educators the ability to teach the newsvendor model with pricing under a capacity constraint using real-life decisions. By 2005, Eastman Chemical Company, based in Tennessee, had created a new specialty plastic, Tritan, which demonstrated heat resistance and durability properties that might allow Eastman to compete in the lucrative polycarbonate plastics market. Development of this product was a major breakthrough for both Eastman and the broader chemical industry. The Eastman specialty plastics team had to contend with numerous challenges, however, before producing Tritan at full scale. First, Eastman had to commercialize a completely new material that only had been produced in the lab; second, the team had to develop a supply chain to manufacture a new component (monomer) and a new product (polymer) simultaneously; and finally, it had to analyze market entrance options given capacity constraints. Thus, the specialty plastics team faced several dilemmas: who should the initial launch partners be, given Eastman's limited manufacturing capacity, and how aggressively should Eastman price Tritan, given that price would drive demand in the launch markets and in new markets?

Early in 2008, Tony Truesdale, President of the Vitamin Shoppe, was preparing for a meeting with the company's investment bankers. In particular, he was wrestling with supply chain issues that were becoming increasingly pronounced in light of the company's aggressive growth plan. Truesdale recognized that it was nearly impossible to effectively manage the company's large and fragmented supply base, resulting in higher than necessary costs and lower than desired performance. The company also relied too heavily on one supplier for a significant amount of the company's volume. Truesdale recognized that it was nearly impossible to effectively manage the company's large and fragmented supply base, resulting in higher than necessary costs and lower than desired performance. The company also relied too heavily on one supplier for a significant amount of the company's volume.

Further, in the company's single distribution center, 95 percent of the available storage capacity was utilized throughout most of 2007; well above what was considered optimal. The lack of space was driving excessive product handling and increasing operating expenses. The company's inbound and outbound transportation strategies also contributed to inefficiencies and unnecessary costs. Operating efficiencies could be achieved if all transportation needs were brought together under one strategic umbrella. Truesdale was certain that in order to reach the company's growth targets and maintain its competitive advantage, addressing these supply chain issues was critical. Students are asked to describe the specific issues affecting supply chain performance and recommend approaches to solving the problems

Workforce diversity is a reality and offers many benefits to business. Nevertheless, managing diversity poses numerous challenges. This case involves religious diversity, focusing on employers' legal duty to accommodate religious practices. In the case, the assembly line at Electrolux's Frigidaire plant in St. Cloud, Minnesota hummed with activity when suddenly a group of Somali workers walked off the line. The Somali employees were new immigrants and introduced cultural and religious customs which were for the most part unfamiliar to management. The employees were Muslim and left the work stations to observe sunset prayers, one of the five daily prayers central to the Islamic faith. The management dilemma presented in the case is balancing the demands of assembly line production with the religious requirements of Muslim workers in a legal and effective manner. There is a substantial epilogue detailing Electrolux response to the situation which can be used as the basis for further class discussion. To help guide this dialogue, a “mini-instructors manual” follows the epilogue.

The case of Bertelsmann China: Supply Chain for Books (B) is situated in China in the beginning of 2006. Bertelsmann Direct Group, the Chinese subsidiary of the worldwide Bertelsmann AG, is one of the leading book retailers in the country. Supply chain management is essential for success in retailing, which is why Bertelsmann puts a lot of effort into the optimization of its supply chain design. As costs are paramount to importance in the low-margin book retailing sector, linear programming methods are applied to optimize the network

This case is used in Darden's first-year core operations class as part of a module on supply chain management. The Musictoday company provided online retailing services for such clients as the Dave Matthews Band and the Rolling Stones. But the lack of a formal inventory-management process had Musictoday concerned about future stockouts that would result in lost sales. This case covers the basics of safety stock within the context of a periodic review system. It introduces students to the periodic review system and provides them with an opportunity to link the optimal review period with the EOQ concept.
