Abstract

This case exposes students to predictive analytics as applied to discrete events with logistic regression. The VP of customer services for a successful start-up wants to proactively identify customers most likely to cancel services or “churn.” He assigns the task to one of his associates and provides him with data on customer behavior and his intuition about what drives churn. The associate must generate a list of the customers most likely to churn and the top three reasons for that likelihood.

Abstract

The organizers of a music festival may use video from the Friday concert to create a DVD to sell to those who come to the Saturday concert. Attendance on Saturday is uncertain, as is the percentage of those who attend on Saturday who will buy the DVD. Is this a good project? If so, what number of DVDs should be burned early Saturday morning and offered for sale at that evening’s performance? By that time, Friday attendance is known, as well as whether it rained on Friday, and there is a forecast for whether it will rain on Saturday. Historical information on these variables may help us predict Saturday attendance using multiple regression; together with the results of a marketing survey, such analysis will help us make better purchasing decisions. This case series (see also the B case, UVA-QA-0708) can be used to illuminate a multitude of concepts that are covered in basic decision-analysis courses. The series starts by examining the role of uncertainty in decision-making, proceeds through the estimation of probability distributions from sample data with multiple regression, culminates in the development of a full decision model, and ends with a qualitative and quantitative analysis (with a tornado diagram) of how to add value and reduce risk. Key pitfalls for students are failing to recognize both limits on sales (supply and demand), incomplete reasoning in the determination of the attendance probability distribution, and oversimplifying the full forecast model.

Abstract

This case, along with its B case (UVA-QA-0865), is an effective vehicle for introducing students to the use of machine-learning techniques for classification. The specific context is predicting customer retention based on a wide range of customer attributes/features. The specific techniques could include (but are not limited to): regressions (linear and logistic), variable selection (forward/backward and stepwise), regularizations (e.g., LASSO), classification and regression trees (CART), random forests, graduate boosted trees (xgboost), neural networks, and support vector machines (SVM).

The case is suitable for an advanced data analysis (data science, machine learning, and artificial intelligence) class at all levels: upper-level business undergraduate, MBA, EMBA, as well as specialized graduate or undergraduate programs in analytics (e.g., masters of science in business analytics [MSBA] and masters of management analytics [MMA]) and/or in management (e.g., masters of science in management [MScM] and masters in management [MiM, MM]).

The teaching note for the case contains the pedagogy and the analyses, alongside the detailed explanations of the various techniques and their implementations in R (code provided in Exhibits and supplementary files). Python code, as well as the spreadsheet implementation in XLMiner, are available upon request.

Abstract

Theoretical basis

This study aims to use a variant from the family of discrete choice models, i.e. the logit model, to analyse the relationship between the Y dependent and X explanatory variables. This model addresses the linear probability model's main drawback by constraining the probabilities of the Y outcome between 0 and 1. The logit model also offers an extra advantage, in that it can provide odd ratio estimations.

Research methodology

This is a compact case written specifically to teach statistics, econometrics and research method. It has an accompanying data set for the case-users to do hands-on statistical analyses. The data set has been collected from a questionnaire survey from the students enrolled in Attitune, i.e. the music school that the case protagonist founded.

Case overview/synopsis

The case revolves around a relatively new music school, Attitune Music, established in July 2017 in the heart of the capital city of a northern state in Malaysia. Michael Lee Wei-Pin was the founder of Attitune Music Sdn. Bhd. He was also one of the four music instructors of Attitune Music. His speciality instruments were the guitar and the piano. The case opens with the case protagonist, Michael, pondering over Attitune’s performance in terms of its music students’ enrolment. Attitune faced a major challenge – its student enrolment had remained more or less constant since its establishment. Low and/or constant number of students could ultimately translate into stagnant or even worse, shrinking revenues for Attitune. To attract more students, Michael had been toying with the idea of injecting new elements into Attitune’s music lessons, something different from what other music schools were offering and that could be unique selling points for Attitune. With this in mind, Michael surveyed Attitune’s students to gather information that could help him gauge the potential and feasibility of his idea.

Complexity academic level

This case is well positioned to be perhaps the pioneer Malaysian teaching case to be written to teach courses in statistics, econometrics and research methods. The case can be easily adapted to teach at either the introductory or at an advanced level.

Abstract

Jane Barrow, CEO of Caprica Energy, must recommend to the board which of three potential “unconventional ” natural-gas development sites in different parts of the United States the company should pursue. The case takes place in January 2011, when the “low-hanging fruit ” of natural-gas production in the United States had essentially been picked. All three of the potential sites (shale, coalbed methane, and tight sands) would require hydraulic fracturing, a process of removing gas that was formerly considered inaccessible by injecting water and chemicals into the ground. Because of emerging concerns about the potential harm “fracking ” can do to drinking water, Barrow must not only analyze which site might be most profitable but also what the potential risks to the environment and area residents might be.

Abstract

Dean Lynn, of Augustine State University's School of Business Administration, has been asked to develop online offerings as a prototype for the rest of the university. The decision he faced was whether to (A) take on the project alone or (B) make a ten-year commitment to a specialized vendor. If option B was selected, the further choice was whether to allow the vendor to handle everything short of instruction with a customized program or to handle only the marketing elements of the task. In the course of considering what to do, Dean Lynn was faced with the financial as well as the qualitative dimensions of the choice. The purpose of this case is to provide students a vehicle to explore the myriad considerations inherent in every organization's decision making process… qualitative as well as quantitative.

Abstract

In the early months of the 2007-08 financial crises, a loan manager faces a real estate financing decision. Should he approve a bullet structure three-year loan to a longstanding client, a legendary Texan developer? The developer, who near retirement downsized his business, is seeking financing for his only project: residential or commercial development on an attractive piece of land in suburban Houston. The loan manager considers the decision in light of the mortgage market turmoil, seeing commercial projects as safer, but also factoring that the residential market could bring higher returns if the market stabilizes soon. The manager collects the data and asks an analyst to assess the risks; that ultimately requires assessing the economics of both projects from both the bank's and the developer's perspectives. The bank could still change the interest rate on the loan to receive adequate compensation for the risk it carries, but the loan manager knows that doing so will change their long-term client willingness to take on the loan.

Case overview

The CEO of Afrotouch Brands, Mr Emeka Emmanuel, must decide what level of investment his company would need to implement to increase its market share and revenue, thus ensuring adequate business competitiveness. Afrotouch Brands was among the leading names in gift items and indoor furniture in Nigeria. Despite the business main outlet in Victoria Island, the highbrow commercial centre in the city of Lagos, it has other high-profile outlets in Port-Harcourt and Abuja. From the very beginning, Afrotouch Brands attracted a lot of well discerning individuals who patronized the business based on the quality, the wide variety, the uniqueness and the lovely ambience of the showroom. The case describes the various investment alternatives needed for business expansion and discusses the probabilities of possible outcomes. Afrotouch Brands could maintain the medium scale indoor furniture they are currently doing, embark on a large aggressive investment to expand the indoor medium scale furniture to a large scale, maintain their business strategy in gift items and accessories or invest in outdoor furniture manufacturing. The challenge is to decide which of these alternative investment strategies the company should undertake in view of the associated levels of risk and uncertainty inherent in their implementation.

Expected learning outcomes

This case study teaches students the following: fundamentals of decision trees construction; calculating and understanding expected monetary values; assessing probabilities; determination of risk profiles for each decision alternative; display of risk profiles graphically; and identification of business alternatives.

Abstract

Alice Monroe was an admissions officer at the Kellogg School of Management at Northwestern University. It was early January 2017 and Alice had enrolled in Northwestern's 403(b) retirement plan two months earlier. After spending a considerable amount of time examining the mutual funds available through the university's retirement plan, Alice had picked two to invest in: a large-cap equity growth fund and a mid-cap equity fund. (See the related case "Selecting Mutual Funds for Retirement Accounts (A).") Her initial allocations were 50% of her investment dollars in each fund.

Upon further reflection, however, she realized these initial allocations were somewhat simplistic. She recalled, from an investments class she had taken at college, the topic of modern portfolio theory, which held that by adding more funds to her portfolio she might be able to achieve greater diversification and thereby reduce the overall risk of her portfolio and/or achieve a higher expected return. Alice now was considering adding an intermediate-term bond fund and a real estate fund to her retirement account.

She hoped to use modern portfolio theory to prove that these new funds would indeed help her diversify her portfolio. If they did, she would also reassess her portfolio weights to determine the optimal allocation.

Abstract

Subject area

The present field-based case study is related to topics in marketing area, more specifically brand management, strategic marketing and business strategy.

Study level/applicability

This case is primarily meant for second-year students in a postgraduate program in business management (MBA). The case could also be discussed in an executive development program on marketing/business strategy.

Case overview

The present case is based on Aava natural mineral water, the brainchild of Mr Behram Mehta, Chairman of Shelpee Enterprises. The case explores at the various marketing strategies adopted by Aava in India. The case traces the brand's foray into the Indian bottled water market as a regional players and its growth as a pan Indian brand. However, in early 2012, the majority of Aava's sales were coming through institutional sales. The brand was facing a challenge of trying to find a foothold in the retail market. The balance between becoming a mass and a premium brand was also looming large. The major question that Aava needed to answer is whether it should restrict itself to the B2B market or whether it should try to penetrate the retail market. Given the latter is more beneficial for the company, the issues of product, pricing and brand communication needed to be revisited since these are not similar for B2B and B2C brands.

Expected learning outcomes

The various learning outcomes of the case include: understanding the differences between B2B and B2C marketing and the need for different strategies for both, apply marketing research findings to introduce a product in a market, evaluate and execute marketing communication strategies based on human behaviour for more effectiveness, evaluate alternatives leading to the right choice of branding/marketing strategy, understand the role of 4Ps of marketing for successful business and industry analysis.
