Case studies

The case would be relevant to undergraduate level or an introductory master's level course in operations management (OM), supply chain management and production.

The case can be used as part of a core OM course in the MBA curriculum or any OM or supply chain elective.

As a highly diversified manufacturing services company, Jabil's S&OP solution supports customers across many industries such as automotive, cloud computing, consumer packaging, healthcare, mobile, retail and telecommunications. Jabil's customers expect a rapid and accurate response to their demand within hours. Previously, Jabil used a series of legacy disconnected planning tools, unsynchronized data required time-consuming manipulation with Excel. Processes were conducted in siloes leading to a “load and chase” approach, which resulted in excess inventory, component shortages and inadequate capacity. The case focuses on one of the Jabil executives, Lizet Tymon (she). Struggling with the issues caused by the disconnected planning tools, Lizet champions implementing a fully integrated suite of services (built on top of the Kinaxis' RapidResponse software platform). The technology solution proposed by Lizet was ultimately implemented across the company, and the project received high marks, and it opened up career opportunities for her. However, it was not a smooth ride at the very beginning. The case focuses on the issues experienced by Lizet, as she is introducing a new technological solution approach and trying to earn support from her team, her peers, her immediate supervisor, her customers and her higher-level executives.

CSS 9: Operations and Logistics

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.

Cutts Floral Distributors, founded in 2004 by Dave Lambe, was a floral wholesaler in Lincoln, Nebraska. The firm became a top wholesaler in the Lincoln area and had expanded its delivery range (all accessed by the company's hand delivery system) up to 100 miles outside of Lincoln. The company credited its success to the expertise of its founder, a professor of horticultural entrepreneurship, and to the company's commitment to customer service. Dave Lambe came to believe that Cutts had exhausted the local market and began looking for growth opportunities within driving distance. Proposed locations for expansion included Kansas City (MO/KS), Denver (CO), and St Joseph (MO). The case provides an in-depth look at Cutts, its competitive advantages, and strategy as the firm faced a critical decision, made more difficult by the uncertainties of the economic recession. This case encourages students to think critically in order to answer the case's central questions: “Should Cutts expand? If so, where?” The complexity of an expansion decision and the multitude of factors that may influence an entrepreneur's decision to expand are illustrated throughout the case.

Dean Adams was given notice to develop an online program with the School of Business Administration as a prototype of online education for the rest of the University. A major task which faced the Dean involved working with University information technology (IT) staff and faculty to choose a learning management system (LMS) to support the online program. After talking with the Chief Information Officer at Seacoast University and appointing a committee made up of IT staff and faculty, the Dean was presented with the committee's recommendation that focussed on two major decisions: first, choosing the LMS product for the University, and second, choosing to locate the LMS product and server either on-campus or off-campus. In the course of considering whether or not to accept the committee's recommendations, Dean Adams weighed the evaluations and justifications as outlined by the committee in the context of Seacoast University's IT situation.

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

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.

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 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.

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.
