Abstract

Social implications

Case explains how female leaders are more concerned about social issues the industry in which they operate could resolve. Obo-Nia, CEO of Vodafone Ghana, showed concern for resolving the digital divide in Africa and offered a collaborative solution. The case also suggests how female CEOs invest in strategic corporate social responsibility (CSR) that could create a competitive advantage for firms. The case also discusses gender diversity issues in the science, technology, engineering and math (STEM) field and how Vodafone Ghana’s CEO tried to enhance gender diversity in the telecommunication sector and Vodafone. Obo-Nai did not emphasize gender diversity from a CSR perspective but believed in a business case for gender diversity, as an increase in participation of women in the STEM workforce could help the telecommunication sector innovate faster and resolve the digital divide challenge while also empowering women working from the informal sector.

Learning outcomes

What is the significance of a digital divide and the societal role of the telecommunication sector; Why female CEOs are more concerned about CSR and how CSR makes not charity but business case; Why female CEOs are more inclined toward collaborative strategies and how stakeholders are involved in collaborative strategies for reducing the digital divide; Exploring various strategies for enhancing gender diversity in the STEM field and the significance of gender diversity in the STEM field.

Case overview/synopsis

The case is about the challenges faced by Patricia Obo-Nai, the first female CEO of Vodafone Ghana, to bridge the digital divide in Africa while doing so in a profitable manner. Obo-Nai was an engineer by profession and won several awards as she rose to the post of CEO in Vodafone Ghana in 2019. During the COVID-19 pandemic, she took several corporate social responsibility (CSR) initiatives, such as making internet service freely available in certain schools and universities so that education could continue. Obo-Nai also emphasized gender diversity within Vodafone and urged other telecommunication players to focus on gender diversity from a social responsibility perspective because it was essential for innovation. Under Obo-Nai’s leadership, Vodafone itself launched several new products. She called for a multistakeholder collaborative approach to bridge the digital divide and to make 4G internet affordable in Africa. Obo-Nai collaborated with competitors like MTN Ghana to enhance Vodafone Ghana’s roaming services.

Complexity academic level

This case is intended for undergraduate or graduate-level business and management courses, especially international business and society, CSR and leadership courses. Graduate students in public policy may also find the case compelling.

Case overview

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.

Expected learning outcomes

The teaching objectives include: understanding and appreciating the supply chain complexities experienced by a global contract manufacturer; helping students think critically regarding the issues around the sales and ops planning; identifying the data needs for the operation and management of a worldwide, connected supply chain; investigating agile solution approaches for information sharing, decision-making and decision-sharing; and exposing the challenges associated with a large-scale technology adaptation.

Social Implications

This case study describes the supply chain challenges experienced by a global manufacturing solutions provider and illustrates the technology adaptation led by a female executive.

Abstract

The business-travel department of American Express is facing rapid growth in demand but is plagued with overstaffing in some offices because of the broad distribution of client demand. Management's challenge is to reduce costs in local offices while maintaining a high level of service. One alternative under consideration is a centralized regional business-travel center to handle reservation functions for up to 20 other Amexco offices. This case gives students the opportunity to apply queuing theory to a practical situation. Normally, in order to facilitate the numerous calculations required, it is used with the UVA “QUEUE” program.

Abstract

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?

Abstract

Supply chain network design choices and the challenges in implementing and understanding how alternatives influence firm performance are key management skills that can be applied to the case of a global company, Kulicke and Soffa Industries, Inc. (K&S), and its expansion strategy. Suitable for the MBA, EMBA, GMBA, and executive education programs, the case explores the decision to expand the company's tool bonding capacity in order to manage its growth. The question becomes whether to grow current operations in Yokneam Israel or seek alternative sites. And if it was decided to seek a location outside of Israel, where exactly should the company go?

Abstract

This case requires a decision on the possible consolidation of three Midwest business-travel centers. Significant cost savings in service representatives can be achieved by combining the front-end (booking) operations. The sensitivity of cost to service-productivity levels and customer waiting time is also explored. This case and related materials can be used as part of the Workforce Planning Module.

Abstract

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.
