In early 2014, recent Stanford University graduate Tyler Shultz was in a quandary. He had been working at Theranos, a blood-diagnostic company founded by Elizabeth Holmes, a Stanford-dropout wunderkind, for almost a year. Shultz had learned enough about the company to realize that its practices and the efficacy of its much-touted finger-prick blood-testing technology were questionable and that the company was going to great lengths to hide this fact from the public and from regulators.

Theranos and Holmes were Silicon Valley darlings, enjoying positive press and lavish attention from potential investors and technology titans alike. Just as companies like PayPal had revolutionized the stagnant payments industry and Uber had upended the for-hire transportation sector, Theranos had been positioned as the latest technology firm to substantially disrupt yet another mature sector: the medical laboratory business. By the start of 2014, the company had raised more than $400 million in funding, and had an estimated market valuation of $9 billion.

Shultz's situation was exacerbated by the fact that his grandfather, the highly respected former US Secretary of State George Shultz, was on the Theranos board and was one of Elizabeth Holmes's biggest supporters.

But Tyler Shultz worried about the customers he was convinced were receiving highly unreliable and often inaccurate blood-test results. With so much at stake, Shultz wondered how he should proceed. Should he raise his concerns with the firm's investors? Blow the whistle externally? Report to industry regulators? Go away quietly?

This case and its subsequent four brief follow-up cases are based largely on interviews with Tyler Shultz, and outline the dilemma he faced and the various steps he would take both to extricate himself from his unsavory position and let the public know the full extent of the deception at Theranos.

Five optional handouts are available to instructors to further discussion after the case has been debriefed. The handouts serve as additional decision points for the students if your class time permits.

This case study is intended to supplement postgraduate business learning with the facilitation of an academic practitioner. The case draws on a culmination of subjects, and the participants are encouraged to juxtapose the case information with their professional experiences; however, the primary focus of the case material will be centred on strategy, innovation, and entrepreneurship.

The primary audience for the teaching case is management education programmes including: Master of Business Administration (MBA), Postgraduate Diploma (PGDip), specialist Masters in Management, and certain Executive Education programmes.

This case is about protagonist Ndabenhle Junior Ngulube, the cofounder of an innovative technology-enabled insurance intermediary company called Pineapple. The company has identified an opportunity to resolve the inherent conflict of interest within the insurance industry, as well as the grudge association of non-life insurance purchases. While the competitive landscape of the sector is traditionally dominated by a few large incumbent market participants, Pineapple's digital distribution strategy is more effective at converting ‘clicks-to-clients’, at a fraction of the typical customer acquisition cost. The peer-to-peer business model also allows for superior risk-selection, greater affinity, and lower incidents of fraudulent claims. Ndabenhle and the team develop the company's customer acquisition strategy by drawing on technological trends, reputation drivers, and a concentrated social media approach that focusses on trust, access, product, and value. But, as 2020 begins, Ndabenhle faces choices about the means and methods of scaling the business operation. The case documents the first few years of Pineapple's operations, with a strong focus on business model innovation, distribution, scalability, and technological integration.

Winstar Communications was a successful and fast growing telecommunication company in the 1990s and early 2000s. However, in the early 2000s, the company started to struggle financially. In 2000, Grant Thornton audited Winstar, issuing an unqualified opinion. After Winstar went into bankruptcy in 2002, investors started to question the quality of the audit. This teaching case is based on the Gould v. Grant Thornton case that was tried in the United States Court of Appeals in 2011/2012. It provides accounting students with an opportunity to learn about auditing procedures and the consequences when auditing procedures are not correctly followed.

The learning outcomes of this study are to identify and discuss ways in which energy consumption in a residential educational institute can be reduced by improving demand-side energy management for sustainable development; summarise the challenges that an institute faces in transitioning to a more environmentally friendly mode of operations concerning energy management; illustrate the difference between operating expense and capital expenditure methods used for solar rooftop projects from the perspective of Goa Institute of Management (GIM); and analyse different project proposals for solar rooftop power generation energy using capital budgeting techniques.

Dr Ajit Parulekar, director at GIM, was evaluating the steps taken over the past few years for sustainable energy management to understand their impact and consider ways in which to take the environmental sustainability agenda forward. One of the projects that he was considering was the rooftop solar power plant. GIM had received proposals from several different vendors and evaluated three proposals out of these. He needed to decide on the capacity of the rooftop solar power generation and the type of contract that he should get into for the implementation of the project. This case study describes the differences and highlights the advantages and disadvantages of all the mentioned models with respect to GIM.

This case study is suitable for post-graduate level management students, as well as for undergraduate-level finance and management students.

Strategic innovation through the deployment of a sophisticated collection of information systems and technologies to help accomplish financial inclusion for the urban poor.

This case is suitable for graduate courses on strategic planning and innovation.

Janalakshmi Financial Services (JFS) is a microfinance company that seeks to serve the financial service needs of the urban poor, a market segment with huge growthpotential. This operation involves large numbers of cash transactions making effective control mechanisms necessary. However, small margins make an innovative strategy necessary. JFS states that information technology (IT) is its DNA. The way in which the leadership team used a variety of ITsolutions to create an integrated set of well managed operations provides a very useful lesson in managing the process of strategic innovation.

The primary learning objective is to help the student understand the impact of strategic innovation through the use of information systems and technologies. This is achieved by helping the student to: connect the abilities provided by information technology to the social objective of financial inclusion; understand what financial inclusion means to the urban poor and how this segment differs from other microfinance and banking segments; assess the approach (related to organizational design as well as systems) JFS has employed to accomplish the objective of financial inclusion among the urban poor in India; analyse the systems and processes JFS has used to deliver services to its target market while making processes more transparent and efficient at JFS; and assess the risks to which JFS is exposed throughits business activity as well as the use of information technology.

The learning objectives aim to provide an understanding of the changing nature of consumer payments and the impact upon both businesses and consumers. This can be achieved by examining the case through the lens of stakeholder theory, which posits that businesses are “responsible … to ‘those groups and individuals who can affect or be affected by their actions.’” Collectively, those groups and individuals are known as stakeholders and they commonly include “customers, employees, suppliers, communities and financiers.” In addition to creating value for the owners, businesses should also consider how they can create value for each of their other stakeholders (Freeman et al., 2010, p. 9). In addition, consistent with the theory of management control systems (Chenhall, 2003), the automatic processing of cashless transactions enables businesses to more efficiently record their earnings, commission payments (if applicable) and monitor cash collections. As all data are captured in an electronic format, they can easily understand their sales and profitability through user-friendly and visually appealing dashboards. This, in turn, enables them to obtain a more accurate and timely view of their business and they can appropriately adjust their operations and strategy as a result of this information. Finally, cashless payments enable more accurate and efficient reporting of information to taxing authorities, which decreases the possibility that the affected parties would underreport income and underpay taxes. This is similarly consistent with the theory of management control systems (Chenhall, 2003) because the improved systems of financial reporting assure compliance with tax laws and regulations.

This case was developed using both primary and secondary data sources. The authors interviewed the participants in London and the secondary data collection used relevant sources from appropriate literature and the popular press.

In London, consumer transactions were as plentiful as the eight million people who lived there. While cash was considered “king” in retail, cash payments dropped by 15% across the UK in 2017, and debit and credit cards became the predominant payment method (Kollewe, 2018). Cash represented only 40% of customer payments and was expected to drop to 21% by 2026 (Lyons et al., 2018). This was likely driven by contactless payments whereby consumers preferred the speed and ease of being able to “tap and go.” As businesses were charged fees to accept credit card payments, many expected that small businesses would insist on cash for small transactions. Instead, some banished cash completely. Insights from two London businesses helped explain why some were dropping cash and completely embracing cards.

This case can be used in a variety of undergraduate level courses to discuss trends in customer payment methods and the decisions of some businesses to completely abandon cash. Some example courses and suggested supporting materials include the following: • Consumer behavior • Entrepreneurial finance • Survey of accounting • Introduction to financial accounting.

Gary Parr, deputy chairman of Lazard Freres & Co. and Kellogg class of 1980, could not believe his ears. “You can't mean that,” he said, reacting to the lowered bid given by Doug Braunstein, JP Morgan head of investment banking, for Parr's client, legendary investment bank Bear Stearns. Less than eighteen months after trading at an all-time high of $172.61 a share, Bear now had little choice but to accept Morgan's humiliating $2-per-share, Federal Reserve-sanctioned bailout offer. “I'll have to get back to you.” Hanging up the phone, Parr leaned back and gave an exhausted sigh. Rumors had swirled around Bear ever since two of its hedge funds imploded as a result of the subprime housing crisis, but time and again, the scrappy Bear appeared to have weathered the storm. Parr's efforts to find a capital infusion for the bank had resulted in lengthy discussions and marathon due diligence sessions, but one after another, potential investors had backed away, scared off in part by Bear's sizable mortgage holdings at a time when every bank on Wall Street was reducing its positions and taking massive write-downs in the asset class. In the past week, those rumors had reached a fever pitch, with financial analysts openly questioning Bear's ability to continue operations and its clients running for the exits. Now Sunday afternoon, it had already been a long weekend, and it would almost certainly be a long night, as the Fed-backed bailout of Bear would require onerous negotiations before Monday's market open. By morning, the eighty-five-year-old investment bank, which had survived the Great Depression, the savings and loan crisis, and the dot-com implosion, would cease to exist as an independent firm. Pausing briefly before calling CEO Alan Schwartz and the rest of Bear's board, Parr allowed himself a moment of reflection. How had it all happened?

An analysis of the fall of Bear Stearns facilitates an understanding of the difficulties affecting the entire investment banking industry: high leverage, overreliance on short-term financing, excessive risk taking on proprietary trading and asset management desks, and myopic senior management all contributed to the massive losses and loss of confidence. The impact on the global economy was of epic proportions.

The learning outcomes are as follows: Understand the concept and characteristics of Bottom of Pyramid (BoP) markets; understand the concept and characteristics of frugal innovations; understand the Design Thinking approach to product design and how it might be useful to develop frugal innovations for BoP markets.

The case details the journey of a group of students at a premier engineering college in India. The group aimed to develop and implement a social innovation that addressed a serious and important health issue – menstrual hygiene practices among urban slum dwellers in India. The case begins with how a chance visit to an NGO inspired a pair of students to take up this issue, how the project unfolded at their college, the challenges faced in their journey and, finally, an outcome that was only a partial success. It raises important questions of challenges that are specific to bottom of pyramid markets in emerging economies. The case can provide a context for discussions on approaching frugal innovations from a Design Thinking perspective.

This case can be used in social innovation courses/modules at an undergraduate or graduate level in social innovation and social entrepreneurship courses. The case is best positioned towards the beginning of the course as an overview of the process of Social Innovation, and to discuss the relevance of concepts of BoP markets and frugal innovation.

In November 2005 Fidelity Homestead, a savings bank in Louisiana, began noticing suspicious charges from Mexico and southern California on its customers' credit cards. More than a year later, an audit revealed peculiarities in the credit card data in the computer systems of TJX Companies, the parent company of more than 2,600 discount fashion and home accessories retail stores in the United States, Canada, and Europe.

The U.S. Secret Service, the U.S. Justice Department, and the Royal Canadian Mounted Police found that hackers had penetrated TJX's systems in mid-2005, accessing information that dated as far back as 2003. TJX had violated industry security standards by failing to update its in-store wireless networks and by storing credit card numbers and expiration dates without adequate encryption. When TJX announced the intrusion in January 2007, it admitted that hackers had compromised nearly 46 million debit and credit card numbers, the largest-ever data breach in the United States.

After analyzing and discussing the case, students should be able to:

• Understand imbedded operational risks

• Analyze how operational risk decisions are made in a firm

• Understand the challenges in the electronic payment transmission process, which relies on each participant in the process to operate best-in-class safety systems to ensure the safety of the entire process

• Recognize the sophistication of IT security threats

In January, 2007, TJX reported that it had suffered from a computer intrusion. The company was sure neither of the identity of the perpetrators nor of how many customers were affected. A deeper analysis revealed that the intrusion had started earlier and affected more customers than previously thought. Ensuing investigation concluded that TJX was collecting unnecessary information, keeping it for too long and employing obsolete and insufficient safeguards. TJX denied any wrongdoing but implemented most of the recommended remedies to strengthen their security.
