This case provides students an opportunity to learn about major concepts of statistical process control, particularly the process control charts, process capability index, and six sigma quality. The protagonist of the case is a third-year business student majoring in operations management, who was working as an intern at Germagic Biochemical Technology (GBT) during the summer of 2021. The intern was tasked with assessing the quality performance of the production process of Germagic 4H Hand Sanitizer, as measured by the actual filled volume within the specifications of 500 ± 10 ml. By using this case study, students can easily relate to the intern's experience as he goes through the entire process of designing the control charts, collecting the data, ensuring the process is in statistical control and stable, and eventually computing the process capability index to determine how much improvement should be made in order to achieve the six sigma quality. This case will cover many technical issues in developing process control charts and the process capability index. Students should be able to complete the necessary calculations to develop the X-bar and R charts to monitor the process mean and range. After the process is found to be in control and stable, students can move on to compute the process capability index with reference to the design specifications and then make conclusions about how capable is the current production process to produce quality products. More importantly, students should be ready to discuss many managerial issues that the intern would face, including how to communicate complicated statistical concepts and the implications of six sigma quality for both manufacturing and service businesses to his supervisor, who is interested in expanding the scope of six sigma quality to the company's other business areas.

This case features Isabella Couchet, the chief operations officer of CaLNG, a company that planned to sell liquefied natural gas (LNG) to help California utilities better match supply and demand through peak shaving. The price of natural gas drawn from the California pipeline infrastructure increased with sudden huge demand spikes during the summer and winter peaks, so the ability to use LNG to fulfill demand during peak periods would be a significant financial benefit to utilities. CaLNG planned to receive LNG at its Coos Bay terminal in Oregon and then transport it to California using specialized trailers. It had to design its LNG supply chain while considering the costs of storage facilities and transportation. CaLNG could build a centralized tank farm at Coos Bay and, from there, use a large number of trailers for on-demand delivery. Alternatively, the company could build satellite tanks at utilities, an option that would require fewer trailers because the satellite tanks could be filled during off-peak periods.

Access to clean water is so critical for development and survival that the United Nations' Sustainable Development Goal number 6 (SDG-6) was to ensure availability and sustained management of water and sanitation. The World Health Organization (WHO) in 2006 estimated that 97 million Indians lacked clean and safe water. Fluoride and total dissolvable solids (TDS) in drinking water were dangerously high at many parts of rural India, with adverse impacts. On the other hand, buying clean drinking water from commercial vendors at market rates was not a realistic alternative, a costly recurring expense that much of India's rural population could not afford. The case tracks the efforts of Huggahalli, head of the technology group of Sri Sathya Sai Seva Organisations (SSSO), to devise a sustainable solution to the drinking water problem in rural India that is low on cost, high on impact. They eventually develop a model that satisfies all these criteria and becomes the basis for a project called Premamrutha Dhaara. Funded by Sri Sathya Sai Central Trust, the project aims to install water purification plants in more than 100 villages spanning six states in India, with the ultimate goal of turning over plant operations to the beneficiary villages and setting up a welfare fund in each village from the revenue generated. Social service projects, particularly in developing countries, have their unique challenges. The case highlights the importance of performing feasibility analysis as part of the project planning in social projects. The case also describes how the financial and operational dimensions of sustainability could lead to a self-sustainable system. The social innovation framework used to deploy the water purification project to achieve broader rural welfare has wider implications for project management, social innovation and change, sustainable operations management, strategic non-profit management, and public policy.

The case goes on to describe the enormous challenges involved in building the 4.94 km long Bogibeel Bridge in the North Eastern Region (NER) of India. When it was finally commissioned in 2018, it was hailed as a marvel of engineering. With two rail lines and a two-lane road over it, the bridge spanned the mighty Brahmaputra river. The Bogibeel Bridge was India's longest and Asia's second-longest road and rail bridge with fully-welded bridge technology that met European codes and welding standards. The interstate connectivity provided by the bridge enabled important socio-economic developments in the NER that included improved logistics and transportation, the growth of medical and educational facilities, higher employment, and the rise of international trade and tourism. While the outcomes of the project were significant, the efforts that went into constructing the Bogibeel Bridge were equally so. This case study is designed to teach the importance of effective risk planning in project management. Further, the case introduces students to earned value analysis and project oversight in managing large projects. The case centers on Indian Railways' need to quickly discover why the Bogibeel project was not going according to plan. The case also serves as a resource to teach public operations management where the focus is on projects and operations that result in socio-economic outcomes.

Concentrix Corporation (CNX), a technology enabled global business services organization, supported a transport solutions company with its customer management services. In June 2019, CNX's global customer services operation manager carried out an assessment and found irregularities in the credit claim process for CNX's client. The manager needed to reduce the number of irregularities so that CNX's agents did not create a negative experience for the client. Random samples for audit revealed that existing guidelines and control procedures were ineffective in capturing irregularities. What strategy did the manager need to select a sample for audit that could capture the maximum number of irregularities within the allowable audit cost?

Teladoc and Livongo had ridden the tailwinds of the COVID-19 pandemic-and a merger between the two would offer a "one-stop-shop" for technology-driven care for patients with acute, chronic, and specialty care needs. The case study describes the regulatory history of telemedicine in the United States, and the licensing barriers that had inhibited virtual doctors' visits-until the 2020 COVID-19 pandemic forced urgent changes to the ways doctors and patients interacted. Would the Teladoc business model-and the proposed merger with Livongo-help establish the company firmly in the increasingly competitive telemedicine field? Analysts projected the telehealth space would grow at a compounded annual growth rate of more than 20 percent over the coming years. Livongo, with 147 million members, offered software and personalized health coaching to address diabetes, hypertension, behavioral health, and weight management. Did this acquisition make sense for Teladoc?

The case describes the development of artificial intelligence (AI) enabled recruitment automation software Talkpush and how it leveraged the technology of open application programming interface (API) to address changes in consumer's communication preferences, and create a software as a service (SaaS) business. In 2021, Talkpush was handling 12 million hiring conversations per annum, forming one of the largest conversational databases in recruitment. It applied speech recognition to convert audio to text, and recognized over 45,000 "intents" through natural language processing (NLP). Recognizing the vast amount of data-voice, text, and images-that could be mined for business insights or used as training data for machine learning, Talkpush's founder Max Ambruster was eager to look for a strategy to extract value from the company's growing data assets.

In 2020, the chief executive officer of Zhida Environmental Technology, a waste management company based in Nanjing, China, was considering adopting blockchain technology into the company’s work process. With the concept of Internet plus recycling, the company was committed to waste sorting and had introduced innovative household waste solutions. However, new challenges were emerging, including stagnant resident participation rates, low profit returns, competitor expansion, and limited support from the local government. Inherent blockchain technology functions such as digital token services, a transparent recycling chain, and collaborative governance mechanisms could potentially improve the company’s current operations and provide a first mover position in the market. However, the chief executive officer had to thoroughly consider the decision of adopting blockchain technology: What true value could it offer and what potential challenges could arise?

GSH Conserves was an artisanal jam producer in Singapore that specialised in using tropical fruits, such as dragon fruit, lychee, mango, etc., to handcraft high-quality jam in small batches. Founded in 2013 in a home kitchen, the demand for GSH Conserves jam and bottled fruits had grown organically through word-of-mouth over the years. In 2016, GSH Conserves moved to a new factory that could cater to a larger production capacity in order to meet growing demand. However, Edwin Lim, a partner at GSH Conserves, observed that his workers and equipment were often idle. He had to examine the company's current operations, identify inefficiencies and suggest improvements. How would the increase in demand and production batch sizes affect production capacity? Would adding resources help to eliminate bottlenecks? How can he redesign the production process to enhance efficiency without affecting product quality?

Founded in 1885, Crayola has since established itself as US-based iconic brand with a wide array of quality products and deep connections with consumers, retailers, and licensing and business partners. By March 2020, Crayola had achieved category leadership and was outselling the majority of its competitors. It was on trend with new products and online content for educators, parents, and children—all with the goal of inspiring creativity among children. Crayola had also created strong relationships with and earned the respect of retailers, who had come to value the role Crayola played in their business, especially during the two most important retail seasons: back-to-school and Christmas. At the beginning of the second quarter of 2020, Crayola had to make some critical decisions. The rapid spread of the COVID-19 virus across the United States had led to business and school closures across the country (and the world), as well as personal physical restrictions. Crayola needed to immediately focus on three key areas: maintaining company culture, collaborating with partners to preserve the volume of back-to-school revenue, and ensuring a strong supply chain to meet consumers’ needs. These three actions would ensure that Crayola could take advantage of key opportunities and continue creating strong and sustainable relationships with educators, parents, and children.
