Case studies

East Texas Oxygen (ETOX) delivered high-pressure cylinders of gases such as oxygen and nitrogen to twelve wholly-owned branches scattered throughout East Texas and Louisiana. Employees loaded and unloaded individual high-pressure cylinders off of and onto trailers manually and the firm had never had a related accident. Robert Jenkins had been challenged to decrease the cost of supplying the branches with cylinders and other supplies. He was considering recommending the palletization of delivery operations which required numerous changes within the organization. This case required students to determine the best routing for the delivery truck(s) and to determine whether or not the number of trucks and drivers could be reduced under palletization. Students were then required to do a capital budgeting analysis and make a recommendation of whether or not to palletize.

The ABB (A) case describes the situation leading up to a decision that has to be made concerning closing a manufacturing subsidiary of ABB and moving its operations to Thailand. The Plant/subsidiary manager is placed in a conflict position regarding this decision due to the matrix form of management structure employed by the parent ABB. His direct line manager in charge of the global product line wants the move to take place. He has the support of his supervisor, who sits on the Executive Committee of the parent company. The ABB Country Manager for Denmark wants the plant to stay where it is. The subsidiary manager also reports to him, as part of the matrix structure. The subsidiary manager has recently been promoted to his new position, with the support of the Country Manager. The previous subsidiary manager had been promoted to head up a larger, Danish subsidiary of ABB. The previous year, the Country Manager and the previous subsidiary manager had managed to over rule the same request, in no small part, due to their connections within ABB as well as within Denmark. The new subsidiary manager needs to make a recommendation as to what should be done. The ABB Transformers (A) case can be used separately, or in conjunction with the (B) case.

The (B) case follows up on the (A) case. The decision was made to leave the plant in Denmark. It was revisited one year later, and the subsidiary manager is in even more of a quandary. The former Country Manager has been promoted to the Executive Committee of ABB. At a meeting of the new Country manager (not previously from within ABB), the Product Manager, his supervisor from the Executive Committee, the former Country Manager, and the subsidiary manager, the discussion is primarily between the new Country Manager and the Product Supervising Executive Committee Member, who has also been given added responsibility for all of Asia and the Pacific region. The former Country Manager, now responsible for European operations, remains quiet during the discussions. He later notes that this is a relatively small decision in the context of European operations. The subsidiary manager still needs to make a decision, but is now unsure of what has happened during the past year to allow this issue to be raised for the third time. The (B) case can be used to demonstrate how politics, promotions, and transfers can radically alter the environment within the context of a strategic decision. The focus is now on organization culture and power, and on the problems of operating within a matrix structure. The (B) case should be used in combination with the (A) case.

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.

Small to medium-sized enterprises, SMEs, play a critical role in the global economy. They comprise 90% of the global firm population and employ more than 50% of the labor force in the private sector. This case study examines issues related to sustainable supply chain management and social entrepreneurship in the SME context. Being small does matter and the efficiencies of small to medium-sized companies struggling for competitive advantage in the global marketplace warrants consideration. Philosopher's Wool Co., located in Inverhuron, Ontario, Canada, is a woolen producer and woolens product manufacturer that partners with other Ontario wool producers and American wool processors and distributors. Its sustainable vertical supply chain system increased local woolen farmers' revenues contrary to the “conventional” price wisdom in the Canadian woolen industry and turned by-product cost into profitable end use. It also effected social change in its local business community and in global customer relations through resource efficiency and socially responsible employee and consumer policies. However, the struggle to maintain a foreign distribution network and remain competitive and profitable was problematic. Students are challenged to solve the problems of an SME operating in a global economy.

Marketing; customer segmentation; operations and logistics.

Undergraduate business and management students, MBA/MA level application for international marketing modules incorporating customer segmentation and customer asset management.

DHL, the international air express and logistics company, serves a wide range of customers, from global enterprises with sophisticated and high volume supply-chain solutions shipping anything from spare parts to documents, to the occasional customer who ships the odd one or two documents a year. To be able to effectively manage such a diverse customer base, DHL implemented a sophisticated customer segmentation cum loyalty management system. The focus of this system is to assess the profitability from its customers, reduce customer churn, and increase DHL's share of shipments.

Case teaching objectives: to demonstrate the concept of customer segmentation with loyalty management as a total system in a logistics company setting, and to evaluate appropriateness of the classification; to utilize the concept of service tier model within the company's current operations, and to evaluate the effectiveness of the model; to analyze the implementation of the customer segmentation cum loyalty management system and development of the necessary rules required to classify the various accounts into categories; to highlight the possible challenges arising from the implementation of customer segmentation cum loyalty management system, and to discuss possible methods of resolution.

This paper looks at logistics and supply chain strategy.

The paper is appropriate for undergraduate and graduate management students.

By November 2009, realising the competitive pressures created by the regional and global players, Mr Khalid Ahmed, SVP, Economic Zones World (EZW), decided to strategically re-position EZW in the global supply chain map. He knew it would be very challenging in view of changing landscape of international business and he was eager to start formulating his plans.

This case can be used to teach logistics and supply chain strategy as well as the understanding of the development of country level strategy. A better understanding of the demographics and geography of UAE is required.

Decision making, behavioural decision making, heuristics, optimistic bias, confirmatory bias, anchoring bias, ready mix cement (RMC) business in India.

Post graduate management course, executive training program in the subject areas.

Arco is a Projects and Infrastructure-sector company. Some of its key officials, believing that entering the RMC can be beneficial for Arco, plan entry into the manufacturing of RMC but order a feasibility report. The report confirms the hunch and Arco starts the business under the aegis of its associate, EG Ltd (EGL) which is into equipment rental business. At this time a new dimension of reality opens up but the senior officers refuse to accept a revised proposal which is adjusted to the new realities. After a few months and some losses, EGL closes down the RMC plant and rents it out.

This case study is developed with a purpose to provide a basis to discuss how decisions are taken in real life and how various behavioural elements affect the quality of decisions that affect not only the decision makers but many others and their organizations. Focus is especially on prejudice, heuristics and bias that creep into important organizational decisions such as venturing into new business.

Operations management, purchasing and procurement management, inventory management and supply chain.

Introductory courses in Operations Management; MBA level and final year undergraduates in management. Masters level in purchasing/procurement management, inventory management and supply chain management.

The case deals with strategic purchase decision of a basic raw material used in ketchups. Ketchups represent 15 per cent of annual sales at National Foods. Mohammad Iqbal, Head of Supply Chain at National Foods, is confronted with the decision of buying tomato paste for fiscal year 2007-2008. He needs to decide how much paste to order from National Foods' supplier in China and when. He has the demand forecast for the paste for 2008 available to help him make the decision.

The case will introduce the students to issues in strategic buying of a basic raw material that is crucial to production. The case is not designed to teach just the basic concept of trade-off between inventory holding and stock out cost. The students should bring these basic concepts of operations with them to understand how these concepts are combined with knowledge of other disciplines to tackle a complex raw material planning issue. Students learn how to plan for the purchase of a perishable yet important raw material for an organization.

They will get an understanding of what is technological innovation and about the technological innovation process. The importance of organizational factors to supplement technology decisions and innovation will be brought out in the case.

Teaching note.

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
