Case studies

The case describes the fall of Eskom, which in 2001 was named the Financial Times’ Power Company of the Year, but by 2019 was suffering from “systemic corruption, malfeasance, fraud and state capture” that had “compromised the credibility of the organisation and eroded investor confidence”. Eskom’s incompetent management lays the ground for reasonable doubt as to whether the force majeure notice was indeed irresistible. The case suggests several methods available in financial markets to hedge risk – but to what extent are these relevant and appropriate? The main objective of the case, however, is to examine and assess the criteria required to claim force majeure. Two aspects are questionable: Was the virus unforeseeable and was it irresistible? Eskom is “bleeding” R².5m per month because of significantly reduced electricity demand, and while it clearly benefits Eskom to break their supply contract, the consequences for Exxaro are far more dire. And, if carried to conclusion, how would such actions impact the entire economy?

In April 2020 South Africa’s stated-owned electricity utility Eskom sent a pre-cautionary force-majeure notification to Exxaro Limited’s Grootegeluk Coal Mine. The notification, citing COVID-19 as an unforeseeable, external and irresistible event, would have disastrous consequences for the mine’s 25 m tonnes pa coal contract to supply Eskom’s Medupi power station. Not only was the legality of the force-majeure questionable, it was unethical, and not in the spirit of President Ramaposa’s call to businesses to continue paying contractors. The case briefly describes Eskom’s troubled history following South Africa’s 1994 democratic election. It examines the force majeure clause common in contracts, and questions whether COVID-19 meets the criteria of an “unforeseeable, external and irresistible” event.

The case describes the origins of money, touching on the gold standard, the Fed’s 1942 purchase of US debt to fund the “war effort”, Bretton Woods (1944), Nixon’s 1971 pulling the currency peg and descent of money from gold to fiat. It also touches on theories of inflation and deflation, quantitative easing (QE) post the 2008 crisis and the “swamp” of (unorthodox) modern monetary theory (MMT). Aside from providing a brief history of monetary policy and economics, the case study seeks to widen students’ understanding of key economic issues including: fiat money, QE, government funding mechanisms, taxation, economic stimulation, inflation/deflation – and of course, the need for an ombudsman to limit excess.

In May 2020, South Africa’s deputy finance minister David Masondo announced that he would support the South African Reserve Bank’s lending to the government. This statement followed President Ramaposa’s earlier announcement of a R500bn COVID-19 stimulus package. The case explores the economic history of money, from barter to gold to cryptos. The case examines the origins of central banks’ printing of money, initially to support the Second World War effort and more recently the 2008 global financial crisis and now the COVID-19 crisis. In particular, the case raises the question of central bank independence – “democratically elected governments always need money, is it appropriate for central banks provide it? And are there limits?”

The case depicts an opportunity for students to be exposed to optimization techniques using linear programming (LP). This case intends to: generate the LP model (identification of objective function and constraints); apply MS-Excel solver to arrive at an optimal solution; analyse manufacturing scenarios; and plan decision dependencies.

VBK Fibreo Tech Industries was a manufacturer of fibre reinforced plastic (FRP) products for industrial and domestic applications. Despite being a new entrant, it managed to exhibit great performance and attract a loyal base of customers. This case brings to light the problem that the company was facing that is demand exceeding capacity. The protagonist of the case Madhav, the Production Manager, was tasked to solve the problem of “product mix”. He was in a dilemma on how to fulfill customer orders while minimizing losses for his company. He knew that while losses were inevitable in the current scenario, they could be minimized with appropriate planning. Students are expected to use data and facts from the case and exhibit to formulate LP, by identifying the objective function and the constraints. They are also encouraged to use MS-Excel solver to find the optimal product mix and understand the decision dependencies.

This case can be used to teach LP in an undergraduate/postgraduate-level course on operations research. Students are exposed to the creation of a mathematical model for optimization and along with devising the implementation plan.

Harley-Davidson's first-ever chief marketing officer has his work cut out for him as the classic American motorcycle manufacturer seeks to curb slowing sales from aging customers. The dilemma: what to do with its less known and unprofitable Buell brand, which has a younger customer base? Which of five options continue its dual-brand strategy, double down on Buell, operate Buell as an endorsement brand, sell it, or discontinue the brand entirely will best attract younger buyers without alienating current diehard customers?

In early 2018, Diana Mulhall was undertaking a career change that would eliminate the need for frequent business trips to Toronto. As a result, she wondered whether she should sell her condo in the heart of the Canadian city or keep it as a rental property to generate income for herself. The housing market in Toronto was booming, so Mulhall believed that the condo would fetch top dollar as a sale. She also thought it would be easy to attract tenants if she kept it as a rental. She had invested in rental property before but never outside of her hometown of Chicago, so Mulhall needed to identify the key risks associated with being a landlord in Toronto.

The premise of the case is how to make best use of customer shopping time while staying competitive and profitable: The increase in the number of ecommerce-based channels and the growth of Amazon and Wal^*Mart have forced brick-and-mortar retailers to seek alternative ways to reach potential customers in a cost- and time-efficient manner. In the U.S., an average of 0.74 hours per day is spent purchasing goods and services, while an average of 1.77 hours per day is spent doing household activities. Regardless of location, customers all have the same 24 hours in a day and only so much of it can be spent shopping.

One of the benefits of ecommerce has been an increase in product variety offered to customers. The online marketplace has enabled consumers in many industries to locate, evaluate and purchase a far wider variety of products than they can with traditional brick-and mortar channels. 30% to 40% of Amazon book sales are titles that wouldn't normally be found in brick-and-mortar stores.

EC-Creamery is an Eau Claire, WI based dairy processor selling yogurt products throughout the Midwest region of the U.S. Inaccurate forecasts have wreaked havoc in the company, leading to frequent stockouts and creating operational challenges. Your task is to draw on the information you obtain from your colleagues to develop sales forecasts, document your choices and procedures and share your thoughts and insights on issues related to forecasting and sales & operations planning.

The learning outcomes are as follows: understanding online, traditional and omnichannel retail and the challenges and benefits of each method; evaluating the effect of consumer buying behaviour on a company’s growth strategy; assessing the effect of changing industry dynamics and technology on consumer behaviour; and understanding the role of consistent customer experience across different retail mediums.
