The case explored whether a novel design for a recycling bin could promote proper recycling behaviours in Singapore. The redesigned recycling bins were initially deployed at different sites around the National University of Singapore to assess their effectiveness among the university community, with promising results. The team now wanted to investigate whether the improved recycling habits observed on campus could be replicated in more diverse public environments, such as shopping malls. The decision for the team was how to implement a field trial of these bins across three shopping malls in Singapore to assess their effectiveness among the general population. The case underscored the importance of human and behavioural-centred design in promoting sustainable practices and discussed primary operational challenges, potential risks, and mitigation strategies to ensure a field study’s success.

Jim Collins, executive director of Harvest Hands, was very active in the day-to-day operations of Harvest Hands, but he also bore the responsibility for planning for the future of the registered charity. Jim together with his wife, Jacintha Collins, founded Harvest Hands in 2020 in St. Thomas, Ontario. In less than three years, their charity had distributed over $7.6 million in rescued food to food banks, missions, and over 120 local agencies. An impressive accomplishment for a volunteer-run charity. Their policy of "We never say no" was quickly pushing the capacity limits of the organization and Jim needed to consider the options for expanding Harvest Hands to keep up with both growing demand and supply.

<p align="justify">By early 2022, Zhongguang Yiyun Supply Chain Management Co. Ltd. had spent six years developing its supply chain management (SCM) and supply chain finance (SCF) platform, ToTrade. The platform collaborated with multiple banks and focal companies to provide integrated SCF services to over 1,000 upstream and downstream small and medium enterprises (SMEs) in China’s Jiangsu, Zhejiang, and Shanghai Provinces. But the site of competition in the Chinese SCF market had shifted from a single company’s SCF capability to its integrated SCF network. Therefore, it was crucial for ToTrade to establish a robust financial supply network in order to enhance the implementation and development of its SCF services. As the volume of ToTrade’s SCF service increased, the company faced key questions: How could ToTrade develop its network to further support its SCF development? And how could the platform effectively evaluate its SCF service performance to better guide this development?

Stembel aims to regain competitiveness by bringing operations back to North America. But the questions remain: how and where should this happen?

Businesses need better planning to make their supply chains more agile and resilient. After explaining the shortcomings of traditional planning systems, the authors describe their new approach, optimal machine learning (OML), which has proved effective in a range of industries. A central feature is its decision-support engine that can process a vast amount of historical and current supply-and-demand data, take into account a company's priorities, and rapidly produce recommendations for ideal production quantities, shipping arrangements, and so on. The authors explain the underpinnings of OML and provide concrete examples of how two large companies implemented it and improved their supply chains' performance.

The Mount Sinai and Mass General Brigham hospital systems took different approaches to automating routine administrative processes, but both found success. The reason: They both combined technical and process knowledge, scored and prioritized individual processes on their automation potential, and involved front-line workers in the implementation. Their experiences hold lessons for other organizations looking to automate routine processes.

This note introduces cybersecurity what it is, why it is needed, and current practices and solutions. While the broad issue of information security is a concern for governments and individuals, this note focuses on internet-related risks facing private-sector enterprises. Cybersecurity is, or should be, front and center in the minds of leaders at companies that are adopting and applying digital technologies to transform how their companies operate. Those technologies continue to advance in some cases at mind-boggling speed. Think artificial intelligence (AI), cloud solutions, enterprise integration, 5G communication, the Internet of Things (IoT), robotics, and more. While these technologies promise to increase an enterprises efficiencies and deliver better customer services, they also introduce a new business risk: cyber risk. Cyber risk means risk of disruption of an enterprises operations, damage to its reputation, or both, caused by the deliberate actions cyberattacks of outsiders (cybercriminals) or enterprise insiders. Once thought to be the responsibility of an enterprises information technology (IT) department, cybersecurity the prevention of and response to cyberattacks is now every employees responsibility, from hourly workers to the board of directors. At the Darden School of Business, this note is taught in the second-year elective Digital Operations class; it would also be suitable in a module covering cyber risks.

Uno Minda Ltd. (Uno Minda) was a leading manufacturer of automobile components for original equipment manufacturers (OEMs) of vehicles running on an internal combustion engine. The Indian company had a strong relationship with automobile manufacturers and long-standing international partners for joint manufacturing of auto components. The Indian market was rapidly adopting electric vehicles (EVs). In November 2021, Uno Minda was determined to establish itself as a leading manufacturer of components for EVs. The company could develop its expertise by investing in in-house research and development, acquiring a domestic or international EV component manufacturer, or forming a joint venture with a renowned domestic or international player in the EV component space. All three options had their pros and cons. Uno Minda had to choose among these.

Nick worked as the weekend shift leader at the fulfillment center of Lee Valley Tools. in Ottawa. The company operated three shifts—a day and night shift on weekdays and a weekend shift on Saturday and Sunday. Reviewing performance statistics, Nick noted that members of the night shifts in the warehouse seemed to be achieving higher performance in order fulfillment and line item fulfillment. On the other hand, the members of the weekend shifts were more aligned with the performance of members of the day shift, which had to deal with deliveries of incoming items and placing these items in the warehouse. Nick wondered why the weekend shift seemed to lag behind. He also wondered whether these differences were significant and meaningful. Nick found that there appeared to be a lag in the picking and packing processes.

This note examines queuing fundamentals and introduces a basic model, variability in systems (arrivals and service processes), and approaches to measure and reduce it. The material also includes practical implications for managing congested systems and helping anticipate and overcome challenges of waiting for service. For MBA students, it can be placed in an operations module on managing variability or queueing. Students can also look for qualitative solutions to address excessive waiting times and hypothesize how their recommendations might affect both actual and the perceived waiting time. For executives, it can serve as a discussion vehicle for operations and customer service.

The Estée Lauder Companies (ELC) is a leading manufacturer and marketer of prestige skincare, makeup, fragrance, and haircare products with annual sales of over $14 billion in 2020. ELC had a long-standing commitment to "High Touch" customer service, inviting and tracking all feedback from consumers. ELC had recently moved from a manual to an automated tracking platform, positioning the company to more efficiently handle customer feedback. This platform and the data it aggregated was put to the test in August 2020 when the Consumer Care Analytics & Insights Group noticed an uptick in contact volume largely generated from China. The team also noticed that the increase was driven almost exclusively by complaints. The spike was especially cause for concern given that ELC had a 100% return policy with no questions asked, so customer complaints often led to returns and lost revenue. In this case, students are asked to consider potential root causes of the increased online customer complaints-and based on their hypotheses, what type of analysis and potential interventions they would recommend.

Chengdu Jwell Co. Ltd. (Jwell) was established in July 2013 as a subsidiary of Pangang Group Investment Co. Ltd., a prominent state-owned enterprise. Jwell served as a comprehensive service platform, facilitating transactions, payments, and billing for various commodities, including steel, vanadium, titanium, and chemicals. Its digital transformation journey began in 2015 with the launch of its e-commerce platforms, and currently, its warehouse management relied on a smart warehouse chain based on digital warehouse technology. However, this approach faced challenges with respect to the real-time sharing of information about cargo and financial data and the lack of adequate support for security in e-commerce transactions, which hindered Jwell's further development.

Hefu Catering Management Co. Ltd. (Hefu) was founded in 2012 as a high-end Chinese noodle chain brand. Its mission was to promote Chinese culture through Chinese fast food on a global scale. In 2018, Hefu experienced significant demand growth. To ensure a steady supply of safe, fresh, and organic foods, Hefu established a centralized kitchen in Nantong, Jiangsu Province, serving 300 restaurants in nearby cities. As Hefu expanded into North and Central China, it faced challenges in delivering fresh food from the centralized kitchen to meet the demands of all its restaurants.

In May 2023, Lei Yang, general manager of Jiangsu Tianan Smart Science and Technology Co. Ltd. (Tianan), based in Wuxi, Jiangsu Province, China, was deciding how to improve his company’s profitability. In its early days, Tianan had sold in-vehicle infotainment devices to automobile companies, and in 2014, it started installing in-vehicle software systems and driver terminals. But from 2010 to 2017, the company lost money. So when the Chinese government announced in 2018 its plan to create internet of vehicle (IoV) pilot zones throughout China, Yang recognized this as an opportunity to transform his company and get rid of its losses. He restructured Tianan’s team, integrated its hardware and software suppliers, took advantage of the government’s help, and turned Tianan into an IoV system service provider. Tianan was profitable in 2020, 2021, and 2022—but Yang was not yet satisfied. Despite the turnaround, the company’s revenue still came primarily from the government, its project delivery capacity was too low to increase sales volume, and its limited bargaining power led to high purchase costs from suppliers. Now, in 2023, what could Yang do to improve his company’s profitability?

In 2021, amidst a world pandemic and escalated racial tensions, Allens Lane Art Center, a non-profit art centre in Philadelphia, Pennsylvania, was losing its leadership and failing to live up to its history-making initiative to promote integration among community members through the arts. The Center's executive director was stepping down and there was no replacement in line. Also, like many small businesses in the West Mount Airy neighbourhood of Philadelphia during this period, the Center suffered low revenue, among other issues. The president of the Center's board of directors had to determine how to bring the small non-profit back to life and generate a reawakened commitment from the board. They had to be prepared to make difficult decisions, including determining how the Center could change its business model while holding to its mission of bringing diverse communities together through the arts.

The case describes the disruption caused by the shortage of chips and sensors in the automobile sector. Although semiconductors used in the automobile sector are essentially low value and cost only a few dollars, they are technologically intensive in terms of both design and manufacturing. Moreover, only a few players in the manufacturing sector have the capability to produce chips, creating an asymmetry in the power equation. Interestingly, the semiconductor value chain is adapting to new geopolitical tensions, and the chipmaking landscape may undergo a significant change in the next 10-15 years. In this context, the case discusses the structure of the semiconductor industry as a whole and its characterization within the automobile sector. It also describes the current sourcing model of semiconductors used by automakers. The main objective is to help students better understand the complex and evolving supply chain structure and its implications for automobile companies worldwide. The case concludes with specific questions about how automakers should restructure their semiconductor supply chains and address future disruptions.
