Discussing statistical error and research design problems and the organizational implications of delivering “good news” at all cost.

This case can be used on basic courses of Public Policy, Marketing Research and Quantitative Methods.

MIDEPLAN on July 2012 showed the results of the CASEN (Caracterización Socio-Económica or Socio-Economical Characterization) survey of 2011. The results showed that poverty was lowered by 0.6 per cent and was greatly highlighted by the media. Opposition coalition and academics started to ask questions about statistical error, which was not yet known. It was revealed that the government asked Comisión Económica para América Latina y el Caribe (CEPAL), a public organization dependent on the United Nations (UN) that was helping Chile to manage the CASEN survey, to review the results and incorporate a variable “y11,” but academics questioned it due to comparability reasons. The statistical error was revealed and it was 0.8 per cent. On October 2012, CEPAL decided to stop helping Chilean institutions.

The key analysis and conclusions which should arise as a result of teaching this case are: The relevance of the statistical error as a key component of research to evaluate data; the importance of fully implementing research design and accuracy of every step to reach valid results; analyze and discuss organizational implications of delivering “good news” at all cost.

Benecol Spread, a cholesterol-lowering margarine, was a product with unusual media-planning challenges. With a narrow target group and unproven market potential, Johnson & Johnson needed to get the most “bang for the buck” from its Benecol advertising. Would a media-planning model (optimizer) requiring executives to quantify their judgment on several key inputs be helpful in this process? A spreadsheet accompanying the case allows students to weight the target groups and to choose among different advertising vehicles to form the best possible media plan.

Case (A) describes the situation at the Northlands Ledger, a newspaper on its way out of business due in large part to its publisher and editor's focus on what they do and want to keep doing rather than on what their customers (readers and advertisers) want. The value proposition to the reader is that “we deliver the paper reliably and give you the latest national and international news.” The value proposition to the advertisers is that “we print your ads accurately and runs them on time.” Both value propositions are outdated, and, even if they were what the customers wanted—which they are not—neither is executed well. The paper's key performance indicators—circulation, classified ads, and commercial advertising—are all in decline, despite the fact that the community it serves is growing. The senior management of the Paulus chain that owns this paper has forced the publisher, Allison, to retire and brought another publisher, Potter, in from one of its other papers, The Sun Belt City Star, where Potter was highly successful. However, he cannot simply transfer his success formula from the Star to the Ledger. Case (B) details his efforts and may be used as a classic example of good change management and leadership practices. Potter established a clear cut set of objectives, formulated a new strategy of responsiveness to readers and advertisers more in line with finding out why they hired the paper in the first place. To implement his new strategy he terminated senior managers and others who he did not feel could contribute to the new paper, and made significant changes in key dimensions of implementation: culture, structure, information and decision support systems, incentives and human resources. Throughout he used a mix of both authoritative and participative change management—a mix that may provoke an interesting class discussion.

Provide a realistic example of leading and managing change with successful transformation of a previously failing company while simultaneously illustrating key dimensions of implementation of strategy.

Key State Blue Cross and Blue Shield Plan (a disguised case of an actual BCBS Plan) is the merged product of three state plans. Initially burdened with a reputation of poor customer service, Key State's executives decided to invest heavily in service improvement, eventually achieving superior levels. Key State's high-quality customer service emerged as a true competitive advantage for its customers, who were primarily businesses and health benefits consultants who influenced corporate purchasers of health insurance. The Key State brand came to be synonymous with personal service, security, choice, and dependability. But the health care insurance market was changing under Key State's feet. Spiraling costs meant that high-quality service became less of a competitive advantage as employers were lured by low-cost, low-service providers. Many employers cut or dropped health care benefits entirely, swelling the ranks of the under- and uninsured, who in turn were extremely price-sensitive when shopping for health insurance on their own. Finally, the health care insurance market was being revolutionized by financial institutions willing to hold health benefit accounts and pay providers directly, thereby eliminating the need for Key State as a mediator. Key State executives were aware of these changes but were challenged by the mindset, culture, and organizational design custom-fit to their business accounts. The case asks the reader to consider whether Key State has the right number of target markets, whether it should have one brand or several for its different target markets, what it should do for the uninsured, and how it should improve its brand experience in light of the industry's changing landscape. All of these decisions will have significant implications for the organizational design of Key State.

To better understand the challenges involved in a successful health insurance company to cope with a rapidly changing and unpredictable environment; to formulate a new strategy and a new organizational design to accomplish this adaptation.

Wright & Company conducted a market research for ‘Fashion Destination’ to determine the consumer purchase intention for a clothing and accessories rental service. Based on secondary research and expert interviews, the consultants came up with a preliminary business model for the service. And through qualitative research they found that consumers indeed had a purchase intention for a clothing and accessories rental service. To validate the conclusion they conducted a primary research by administering a detailed questionnaire and prepared a codebook. The consultants now had the challenge to make an analysis plan to draw appropriate inferences vis-à-vis the objectives of the research.

Data used to develop the case included primary data from employees and supervisors of a commercial floorcovering manufacturing plant in Northwest Georgia. The case company is not disguised.

The survey was developed using existing instruments from the Organizational Behavior and Human Resources Literature. Instruments were listed in Exhibits 2 through 7. The survey administration had the support of the Vice President for Resources and Facilities, and employees and their supervisors were given time to complete the surveys. The data gathered was analyzed by the researcher using SPSS statistical software.

Established in 1957, J&J started as a family-owned business but had grown and diversified its product offerings by focusing on commercial flooring. It survived several economic downturns and remained competitive in a market dominated by more prominent flooring manufacturers. J&J Industries strived to empower its 800 employees with various incentive programs. Employees remained loyal to J&J; many had worked for the company for over 15 years. However, management wanted to measure the impact of empowering and initiatives on employee performance and satisfaction to determine the real power of employee incentive programs. The Resources and Facilities Vice President employed Professor Lopez, a Management Professor, to develop a survey to measure these constructs and analyze the data to guide future incentive programs. Data from the employee and supervisor survey was provided along with the statistical analysis results for interpretation and recommendations for VP Fordham.

The target audience for this case is primarily students in a research methodology course and students studying quantitative regression analysis and interpretation. The focus is predominantly on graduate-level students in Master of Business Administration or Master of Accounting programs in business. Graduate students should have completed courses in management or organizational behavior, business statistics or quantitative methods or data visualization and cleaning as background knowledge for this case. Specifically, students should understand regression analysis and know when and how the tool is used for managerial decision-making.

The case examines the development and launch of an exchange-traded fund (ETF) based on JUST Capital's socially responsible corporate ranking methodologies. The case provides a market overview of Environment, Social, and Corporate Governance (ESG) and socially responsible investing (SRI), what has driven growth in those areas worldwide, and several best-practice investment approaches. Following the overview, the case describes the founding and development of JUST Capital, explores JUST Capital's ranking methodologies, and presents the decision point faced by the CEO: requisite selection of one of three strategies in order for JUST Capital to generate “self-sustaining” revenue.

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.

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.

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.

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.
