Case studies

This case study addresses a number of common transportation management issues. It provides an opportunity to analyse historical freight payment data in order to reduce transportation costs and improve customer service, allowing students to utilise real freight payment data and order shipment history data to make recommendations that have strategic implications for both cost and service performance.

This case illustrates the concept of consolidation and how freight forwarders use it to reduce transportation costs. The student must compare a ship-direct model against vehicular consolidation, then consider temporal consolidation, investigate the differences between a freight broker and a freight forwarder, and develop a rate analysis for use in negotiation.

This case focuses on supplier management through quantitative and qualitative analysis of data from a real company. In the process of solving the case, students determine and operationalize what constitutes a critical supplier, analyse the data provided, and identify the most critical suppliers.

This case study follows GHP Bearings staff as they create a supply chain map. Students will understand the supply chain network as a whole: including the relationships between suppliers and extending beyond immediate suppliers and customers rather than seeing the supply chain as a linear connection. Students will then analyse the entire supply chain network for strategic purposes and decide where should receive the greatest emphasis of management to give a competitive advantage.

This two-part case illustrates the use of economic order quantity to manage conflicting performance measures across different siloed functions in an organization. Part A requires students to assess the costs of various order quantities and quantify the concept of “robustness.“ Part B emphasizes managing the variables of annual demand, ordering cost, inventory carrying cost, and unit price to achieve strategic goals. The student must determine how to lower ordering costs to compensate for increases in the other variables as well as to help guide Just-In-Time implementation efforts.

The COO for Suape Container Terminal, the largest deep–water port in Brazil's Northeast must consider a proposal presented by the users' council that calls for the establishment of a reservation scheme that minimizes the risk of docking delays. Under this proposal, ocean carriers, on the one hand, agree to pay a reservation fee that significantly increases revenue for Tecon Suape. On the other hand, they expect Tecon Suape to compensate them financially when a berth is not available upon vessel arrival. Tecon Suape's management team must evaluate that suggestion, as the team prepares to enter contractual negotiations with the users.

9 million Thin Mints are made every day. In 2015, there was a spike in orders causing production shortages. In this case, students will evaluate how the CEO of Girl Scouts of San Jacinto Council, Mary Vitek, can mitigate the risk of supply disruption and utilize strategic sourcing in order to avoid any further shortages.

The Arbor City Community Foundation (ACCF) was a medium-sized endowment established in Illinois in the late 1970s through the hard work of several local families. The vision of the ACCF was to be a comprehensive center for philanthropy in the greater Arbor City region. ACCF had a fund balance (known collectively as “the fund”) of just under $240 million. The ACCF board of trustees had appointed a committee to oversee investment decisions relating to the foundation assets. The investment committee, under the guidance of the board, pursued an active risk-management policy for the fund. The committee members were primarily concerned with the volatility and distribution of portfolio returns. They relied on the value-at-risk (VaR) methodology as a measurement of the risk of both short- and mid-term investment losses. In its report for the investment committee, the ACCF risk analytics team recommended the daily VaR at 95% confidence as a measure for short-term risk and reported the corresponding numbers. It is now the task of the investment committee to interpret these figures. The case questions guide the executive students to a critical evaluation of both the reported VaR figures as well as of the VaR methodology.

Understanding the concept of value at risk (VaR); Interpreting the results of VaR calculations; Evaluating the appropriateness of VaR calculations; Critical discussion of the VaR methodology.

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.

California telecommunications company Wireworld is considering an acquisition of Nusantara Communications, a subsidiary of Indonesian conglomerate Bakrie & Brothers. Nusantara had invested $50 million in developing the advanced rural telephone system, which had the potential to provide much-needed telecommunications services to the mostly rural Indonesian population. If if were exported, the worldwide market for this product in the next five years was projected to be in the billions. Should Wireworld acquire this small company halfway around the world? Was it prepared to enter the Indonesian marketplace and beyond?

Students will examine a variety of data, including financial projections, in order to decide whether acquiring Nusantara will add value to Wireworld.

A business analyst at Mead Corporation had just begun the process of estimating Mead's cost of capital for the fourth quarter of 1990. As part of her analysis, she hoped to explain why the cost of equity had increased and recommend whether the company should consider the increase a problem.

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.

Quality Wireless has received customer complaints about long hold times at its call center. To address these complaints, it put into place certain process changes at its call center. After one month, the company will now decide whether improvement has taken place.

To develop an understanding of process capability and how an improvement can be statistically validated. To understand the “check” phase of the plan-do-check-act cycle of Deming, using basic statistical principles.

Assumes an understanding of statistical process control and focuses on highlighting the usefulness of Six Sigma quality. Focuses on the issue of a worn bearing at a tire manufacturer leading to a mean shift (while producing defectives). Shows how a Six Sigma process would quickly detect the mean shift while producing fewer defectives.

To introduce the methodology of statistical process control and to illustrate the value of Six Sigma.

Since 1981, the U.S. federal government has operated a price support program to help sugar beet and sugar cane producers and processors. This complex program works through a combination of loans, import quotas, and duties. As a result, sugar prices in the United States are significantly higher than world prices. For example, in December 2001, U.S. consumers paid 22.9 cents per pound, while the world price was just 9 cents per pound. The General Accounting Office estimates that the total cost to consumers is $1.9 billion a year. Uses a simple demand-and-supply framework with real-world data to assess the economic and political consequences of the U.S. sugar program.

In 2005, a wine snob in the critically acclaimed movie Sideways denounced merlot. Subsequently, sales of merlot, including sales for Terlato's Rutherford Hill merlot, declined significantly. Students are asked to evaluate three strategies---rebranding, cutting price, and launching television advertising---that Terlato is considering to reverse this decline. The case should be used with “Student Supplement: Terlato Wines International: Background Note on the U.S. Wine Market and Terlato Wines International,” Case #KEL359.

Students explore the challenge of managing a brand when external factors cause a decline in category demand. They also explore the role of pricing and advertising in managing a small, luxury brand.

This case presents common-sized financials for two companies, each of which is in a number of industries. The companies have different market niches, and students are asked to identify the companies from details provided. The case also allows for financial comparisons among industries.

In 2012 several retailers, including Amazon and Walmart, experimented with same-day delivery. Home delivery of pizzas had been a very successful model in the United States and had been copied all over the world. In contrast, home delivery attempts by companies like Kozmo and Urbanfetch had failed and both companies went bankrupt. The goal of this case is to build a framework that helps students identify the factors that influence the success or failure of home delivery models.

After analyzing and discussing the case, students should be able to:

• Build a basic framework identifying supply chain drivers that are influenced by a firm's decision to offer same-day home delivery

• Understand the tradeoffs that influence the success of a same-day home delivery model

• Identify qualitative factors to be considered when deciding between non-U.S. facility locations, including transportation time variability, consumer perceptions, and cultural differences

Pancho’s Burritos is a high-end fast-food restaurant located in Charlottesville, Virginia. Due to a recent surge in customers, the lines at the restaurant during peak hours are becoming very long and causing excessive customer waiting. To improve current customer wait times and plan for future growth requirements, Francisco “Pancho” Escoba, the proprietor, wants to get a better understanding of the current operational capacity. The key decision Escoba must make is how to redesign his burrito-making process to increase the capacity and reduce customer wait time.

Suitable for an undergraduate or MBA course, the case can be used in an introductory operations course to teach capacity analysis and queuing. The case provides a relatable and understandable setting for students without an operations background to gain a better grasp of basic course concepts and illustrates how interactions between capacity and queuing affect one another. As an exam or review case it works well because it contains standard process calculations that all students should know how to perform.
