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.

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.

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.

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.

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.
