Case studies

The case has the following learning objectives:

1. understand the various types of comparisons that are possible between groups over time and across space;

2. evaluate a policy intervention using relevant data and different methods; and

3. understand the meaning of the phrase “controlling for other relevant factors” in regression and non-regression contexts.

The difference-in-differences (DID) approach is a useful tool for making meaningful comparisons. This case tries to provide a non-technical introduction to the approach using a basic comparison of crime rates among districts in Punjab (Pakistan's largest province). Being the most populous region of the country, Punjab faces many governance challenges, and street crime is one of them. (Exhibit 5 provides additional information about the geographical and administrative setting used in this case study.) In 2016, Chief Minister Shahbaz Sharif established the Dolphin (police) Force in different locations to improve urban patrolling and reduce street crime. There were debates about the effectiveness of the Dolphin Force (DF).

Those who are skeptical of DF point to various situations that were handled incorrectly by DF personnel, as well as other administrative and operational problems in the initiative. Optimists believe it is beneficial and want it to be expanded to other districts and regions. The threat of street crime claims many lives and, according to optimists, necessitates the formation of a special force. Whether the huge resources invested in the DF worth their lot or not can be known through sound statistical analysis that can identify the difference in the rate of crime because of the DF. In this instance, the case provides information to answer the following question:

Is there a significant difference in crime rates between areas where the DF is operating and districts where it has not yet been installed?

In quantitative/statistical analysis classes, the case can be used to teach the DID technique to MBA/MS Applied Statistics/Applied Data Analysis students. It can also be used in undergraduate Econometrics classes.

The learning outcomes are as follows: identify and evaluate the impact of risk factors for health-care organizations during crisis; evaluate the role of different organizational factors in building resilient health-care organizations; define organizational resilience in a health-care context; and apply the effect-strategy-impact resilience framework.

September 2022 found Ranjan Thakur, the Hospital Director at Manipal Hospital, Jaipur (MHJ) reflecting on MHJ’s resilience toward future health-care crises. MHJ was established in the capital city Jaipur of the Indian state of Rajasthan in 2014, as a 225-bed multispecialty unit of the nationally renowned Manipal Health Enterprises Ltd. As the Hospital Director, Thakur had been responsible for navigating his team and the hospital through the multiple health-care related challenges exacerbated by the multiple waves of the Covid-19 pandemic in a large Indian state with a sizable rural and semiurban population. Though Thakur and his team of doctors had worked through the vulnerabilities of their health-care ecosystem, mapping the risks and mitigating the same, Thakur asked himself if they had done enough. He wondered how a health-care institution such as theirs could sustain effective health-care delivery during future crises situations to deliver high-quality health care to the vulnerable communities. Had they effectively mapped MHJ’s vulnerabilities and built resilience into the hospital’s functioning? The backdrop of the case is public health in the state of Rajasthan (Jaipur), and the case is rich in detailing social factors such as behavior issues of patients, doctors and nurses; operational factors such as standardization of treatment and standard operating procedures, availability of resources, clinical concerns; leadership and management of the hospital through the pandemic. This case can be used by instructors to teach organizational resilience building in the health-care context.

• After working through the case and assignment questions, students will be able to do the following:• Identify the difference between core competencies and dynamic capabilities and how they make a difference in a crisis towards building an agile organisation.• Evaluate the support through a collaborative, temporary, trans-organisational system to local manufacturers to achieve agility and sustainability.• Realise the importance of clear expectations exchange and communication between partners to enhance collaboration, even in temporary structures in increasing agility and sustainability.

The COVID-19 pandemic and subsequent lockdowns created a crisis for South Africa and the President, Cyril Ramaphosa called for urgent collaboration between business, labour and government to meet the demand for locally produced Personal Protective Equipment (PPE) and medical devices. The case illustrates this response and collaboration between government, labour and business through a temporary newly formed structure, called Business for South Africa (B4SA). Ross Boyd, Head of the innovation work stream of B4SA which housed the local manufacturing partnership (LMP) was considering his dilemma of how to be agile in sustaining their support to the South African manufacturers even though the LMP was a temporary structure. The local manufacturers had to repurpose their production lines to produce local PPE and medical devices. How could the LMP support the South African manufacturers to sustain their agility in building capabilities during COVID-19? At the same time, Ahmed Dhai, the Group Executive of Operations of Kingsgate Clothing, which was benefiting from the support of the LMP, was reflecting on his leadership in taking decisions to repurpose production and increase capacity during COVID-19. Dhai was considering his dilemma of being agile during and beyond the COVID-19 pandemic. The case features several decisions taken by Kingsgate and offers students the opportunity to evaluate these decisions given the fluctuations in supply and demand of PPE and the leadership that Dhai demonstrated in how he communicated and dealt with his staff during the pandemic. Students could also give recommendations to Ross Boyd and Ahmed Dhai on how they could lead their organisations to be more agile during and beyond COVID-19.

The case study is suitable for MBA or MPhil level on Strategy courses. The case would also find good application in Organisational Behaviour and Leadership courses on Masters level and Executive Education programmes.

Upon completion of the case study discussion, successful students will be able to define and list the steps of time-driven activity-based costing system (TDABC); understand and explain the ideas behind the TDABC; implement the TDABC in customer profitability analysis; draw connections among the cost and profitability analysis; evaluate the importance of better costing techniques in profitability analysis; and make managerial decisions based on TDABC analysis.

Gluten Limited’s financial affairs and operations manager, Fatih, was aware that the company was making very little profit from its operations with its biggest customer. The main reason appeared to be that it delivered its products in bulk to the main warehouses of the customer, which then distributed them to the stores. Fatih believed that products were being sent to stores late, so that their expiration dates passed quickly and they ended up being returned.

The case study documents the past year of Gluten Limited’s delivery operations with one of its biggest customers. It focuses on the effectiveness of its delivery operations and ways to increase profitability by reducing sales returns. The case dilemma involves the choices that Fatih faced following a six-month trial period: either delivering products in bulk to the customer’s main warehouses at lower cost but higher return rates or delivering small amounts directly to stores at higher cost but lower return rates. Fatih needed to decide which mode of customer operations was more profitable and continue that way.

Knowing the importance of determining costs properly in profitability analysis, Fatih made the cost calculations using the TDABC system.

This case was written for use in Cost Accounting and Managerial Accounting classes at the undergraduate level. The focus of the case aligns well with discussions of customer profitability analysis, cost reductions, eliminating non-value-added activities, and profitability of operations. Instructors seeking to emphasize the most suitable costing methods for customer profitability analysis could assign this case.

1. Probabilistic calculations of cost, and profit/loss using standard probability functions

2. Decision tree to find the expected monetary value (EMV) of different options.

3. Monte Carlo simulation for risk analysis.

4. Risk analysis in project management.

Learners will be able to understand and apply the following: how to approach uncertainty in business decisions using probabilistic calculations of cost, and profit/loss using standard probability functions; how to address uncertainty in business decisions by looking forward and reasoning backward, using the decision tree technique and the EMV of different decisions; how to analyse the risk inherent in business decisions by incorporating probability distributions for all critical variables in the form of Monte Carlo simulation; and appreciation of strategic considerations in risk analysis as it applies to project management

The case describes the challenge facing Vilas Birari, the owner and chief executive of Harsh Constructions, a construction company headquartered in Nasik, India. Birari had to decide on the bid for a construction project in September of 2021, during the COVID-19 (COVID) pandemic. Due to successive waves of the pandemic, the state and federal governments announced lockdowns intermittently, causing uncertainty in costs related to labor, material and project completion. The dilemma before Birari was how to set a bid price that was not so low as to incur a loss and not so high as to lose the bid to competitors. The uncertainty made Birari’s decision-making complex. The case invites students to help Birari find an optimum bid price by using various quantitative techniques, such as Monte Carlo simulation and decision trees.

This case is intended for students of management at a master’s level, in an elective course on management science, which is often also known as decision science. This compact case can be positioned in the second half of the course, when exploring risk management using computer simulation as a tool. The case serves both as an introduction to using simulation to manage uncertainty as well a contrast with simpler methods that are covered earlier in the course.

The learning outcomes of this study are as follows:

1. comprehending foundational dimensions of brand equity and criteria to compare the use of traditional and new media in leading brand communication appropriateness and performance;

2. understanding and evaluating implications of leading brand communications during times of crises; and

3. creating recommendations for leading brand communication preparedness and response to crises.

On 16 August 2020, Dr Barbara Jensen Vorster, Senior Executive Manager, Communications and Marketing of the Gautrain Management Agency (GMA), in Midrand South Africa, considered her dilemma of adapting their communication approach during COVID-19 and beyond the current crisis. The GMA relied on traditional media and the crisis created an opportunity to rethink their entire communications approach. It was important to the GMA communications team to keep the Gautrain commuters connected even though they might not be using the Gautrain during the lockdown of COVID-19. Jensen Vorster believed that a brand should be adaptive and continue even when a service is not running. Jensen Vorster had to lead her communications team when they were all working from home, and they had to keep commuters informed of the requirements during the different levels of lockdown in South Africa. Their various campaigns during this time purposefully communicated with commuters and the various “staying home” initiatives with the intention of lifting spirits. The communication outreach during the COVID-19 pandemic switched over to social media communications out of necessity; however, was that ideal communication during a crisis? While most of the case focuses on this external communication, the case pays attention to some internal communication initiatives by Jensen Vorster with her own team and for the Gautrain’s staff. The question is whether brands should shift from traditional media to new media campaigns during the 21st-century crises? Students will get the opportunity to compare the use of traditional and new media during crisis times. How might they approach their brand communications during COVID-19 and in preparation for future crises?
