Favorite Business Case Studies of MBA Graduates

Picture it. You’ve made it. You’re the CEO.

You make the big decisions. You set the priorities – and the tone. In good times, you’re admired and celebrated. When an emergency strikes, all eyes fall on you. In the limelight, leaders can either seize the opportunity – or reveal their shortcomings when it matters most.

In literature, you have morality tales, stories of right-and-wrong where the virtuous are rewarded for self-control and the wicked suffer for their vices. In business school, that medium is translated into case studies. True stories – sometimes ripped straight from the headlines – cases often follow how business leaders respond to adversity, be it a product recall, supply chain bottleneck, or market disruption. Other times, they take deep dives into operational innovations, such as Toyota’s lean manufacturing principles or Netflix’s pivot from mail subscriptions to live streaming.

In the end, cases ask students to decide how they’d respond to a situation, given the same unreliable information, conflicting agendas, limited time, and uncertain outcomes faced by leadership. It forces them to consider the perspectives of stakeholders like customers, suppliers, and employees – not to mention media coverage and political blowback. Unlike a morality tale, where a reckoning is swift and clear, a case study offers no clear answers. Instead, business students often debate between bad-or-worse, weighing the value of various constituencies, all while pitting long-term strategy against short-term finances.

HOW BENIHANA CHANGED A WORLDVIEW

The details of business models can quickly fade from memory. Stories? They leave an indelible mark on MBAs. In some cases, they are cautionary tales about hubris, scaling, or pricing. In others, they are humbling reminders for students to listen to classmates, whose varied experiences and deep expertise enable them to formulate more holistic solutions. If anything, cases provide a catalog of potential responses, along with practice in researching scenarios, identifying potential solutions, and persuading high-level stakeholders.

Among the most famous cases is Benihana, published by Harvard Business School over 50 years ago. A Japanese steakhouse, Benihana examined how structure and service interconnected to deliver a seamless dining experience. It was also the first case that Rebekah Koster discussed after she started at Brigham Young University’s Marriott School. Having dined at Benihana several times, Koster was struck by how she took so many details of the restaurant’s inner workings for granted.

“The case opened my eyes to the idea that every business – even something as familiar as a restaurant – can be analyzed through strategy, operations, and economics,” Koster writers. “What fascinated me was how the case broke down elements I had previously taken for granted: the layout of the restaurant, the hibachi cooking format, the limited menu, and the pacing of service. Each of these decisions was intentionally designed to improve efficiency, increase table turnover, and create a memorable customer experience. Suddenly, what I had always seen as entertainment at dinner revealed itself as a carefully engineered business model.”

More than that, Koster, the Benihana case “fundamentally shifted” how she viewed the world from that point forward. “It showed me that business strategy is everywhere, often hidden in plain sight. Since then, I’ve found myself analyzing the systems behind every day experiences, from restaurants and events to retail and travel. The Benihana case wasn’t just my introduction to the case method; it changed the way I observe and think about how businesses are designed to succeed.”

OVER 20 UNFORGETTABLE CASES

What were some other cases that left a mark on MBAs? Earlier this year, Poets&Quants asked the Best & Brightest MBAs and MBAs to Watch to share which case studies made the biggest impact on their thinking (and the biggest lesson they gained from them). From Lego to Starbucks to Walmart, here are the cases you’ll want to discuss in business school.

“One of the most impactful case studies for me was the AccorHotels Digital Transformation Case, which examined how a traditional hospitality company responded to the disruption caused by Airbnb.

The case highlighted how Airbnb, an asset-light, platform-based model, rapidly scaled into a global player and fundamentally changed customer expectations in the hospitality industry. In contrast, AccorHotels was a traditional, asset-heavy organisation that had to rethink its entire business model, customer experience, and organisational structure to stay competitive.

What made this case particularly valuable was how it brought together multiple concepts from the course, including disruption, platform business models, digital transformation, and corporate strategy. Accor’s response involved not just investing in technology, but also acquiring digital platforms, redesigning customer journeys, and driving deep cultural change within the organisation.

The biggest lesson I took away was that responding to disruption is not just about adopting new technology. It requires a fundamental shift in how a company creates and delivers value. Incumbents often underestimate disruptive threats, and by the time they react, the competitive landscape has already changed.

For me, this was especially relevant as it reinforced the importance of anticipating change early and being willing to rethink core business models rather than incrementally improving existing ones.”

“The BlackRock ESG Investment Dilemma in ACCT 688 (Sustainability Reporting and Analysis). As the world’s largest asset manager, BlackRock publicly committed to ESG investing through Larry Fink’s Annual Letter to CEOs and then got hit from every side. Republican state treasurers pulled funds over fiduciary concerns, climate activists stormed the offices demanding more action, and even former BlackRock executives questioned whether ESG ratings meant anything at all. The lesson that stuck with me is that leadership in finance isn’t about finding the answer everyone agrees with, it’s about making a call when the data is messy, the stakeholders are loud, and there’s real money on the line. That’s the kind of decision-making I want to be ready for.”
Jean Remy Mizero, American University (Kogod)

“The most impactful case study during my MBA was the Walmart Case in our Strategy course with Professor Richard Wang. What made it memorable was seeing how all elements of strategy come together as an integrated system. Using the framework of value creation, value delivery, and value capture, we examined how Walmart’s promise of everyday low prices was supported by a tightly connected set of operational choices, from logistics and supplier relationships to information systems and disciplined cost management.

The biggest lesson I took from the case is that many companies copy visible tactics like low prices, but very few replicate the invisible architecture behind them. Walmart’s advantage came from the system that supported its strategy, distribution networks, supplier integration, culture, and data infrastructure, not from the price tags on the shelves.”
Drin Govori, Babson College (Olin)

“The Planet Fitness case from my Strategic Management course was one that stuck with me. The health club industry checks almost every box for structural unattractiveness: low barriers to entry, intense price competition, high fixed costs, and a long list of substitutes. Porter’s Five Forces painted a bleak picture. Despite this, Planet Fitness thrived by being ruthlessly clear about what it was not. No squat racks, no personal trainers, no juice bars. Every omission was intentional, and together they carved out a position no one else occupied.

The biggest lesson was that knowing where you stand – and being honest about it – is the foundation of any good strategy. You cannot compete everywhere, and trying to often means winning nowhere. That framing resonated with me personally. As someone who transitioned careers across both industry and country, I have had to develop a clear sense of my own positioning: what I bring that others do not, where I can create the most value, and what I should simply stop trying to be.”
Hyemin Lee, Boston College (Carroll)

The case studies in Negotiations Lab taught by Mark de Rond were really engaging, and I learned a lot – not just about the strategies and techniques of an effective negotiation, but also about myself. One powerful case study was the September 11 case. We were put in small groups, with each person representing different stakeholders in the aftermath of the attacks – including the developer, New York City, New York State, the insurance company, and the representative of the families of those impacted by the disaster. From there, we had to negotiate a mutual outcome for the site rebuild.

I played the role of the developer, and learned that it can be very difficult to achieve consensus during multi-party negotiations, especially where everyone has different interests. More importantly, I learned that negotiations are not purely rational – rather, you must have empathy and acknowledge the emotions of those involved so that they feel heard and understood. It is only after you have done this that you can begin to find common ground and move towards a resolution.
Steven Pillon, Cambridge Judge Business School

“The most impactful case from my Booth experience was “Optimization and Expansion at OpenTable.” OpenTable’s history is a perfect example of platform development with network effects. Chuck Templeton recognized that restaurants lacked the infrastructure necessary for online booking in the early 2000s, and OpenTable subsidized the cost of the necessary hardware for those businesses. This kickstarted a platform that eventually connected diners and restaurants, with each side benefitting from more of the other joining the platform. This flywheel propelled OpenTable’s near-monopoly for over a decade.

The most important takeaway from this case came from understanding the erosion of OpenTable’s business. OpenTable charged a per-cover fee for their services, creating a high cost for restaurants as a portion of every reserved seat went to OpenTable. When Resy came along with a less costly monthly subscription option, there was a place for that frustration and new restaurants flocked to the more affordable platform. Network effects can sustain a dominant platform for years, but they can’t protect an undifferentiated product from a cheaper competitor forever. OpenTable’s competitive advantage was real, but resentment from restaurants became a true vulnerability, and now, there are several credible players in the dining reservation market.”
Chad Shimozaki, University of Chicago (Booth)

“It’s a Harvard Business School case titled “Balancing Act: Deborah Lovich,” which I read for an assignment in my Topics in Leadership: Women in the Workplace class taught by McClean. I was surprised that there was even a case about a woman executive who was caught between two things she refused to sacrifice: her career and her family and the structural cost women pay when ambition meets a system not built to support them. I often heard these stories through personal connections, but rarely examined in a formal case study. Deborah had sacrificed enormously to reach a once-in-a-lifetime seat at the table as the youngest and only woman on BCG’s Executive Committee. Stepping back felt like erasing 15 years of work while signaling to the firm that ambitious women couldn’t sustain leadership roles. Mark had put a 12-year MIT/Harvard M-PhD career entirely on hold to hold the family together. After years of functioning as a single parent he was emotionally broken and needed her to scale back so he could finally reclaim his own professional identity. McClean encouraged us to consider the case from both perspectives, Deborah’s and Mark’s.

Not only did I find lessons, but it also reinforced lessons I have experienced. Notably, they involved the trade-offs leaders face at the top are not merely personal, they are strategic decisions about allocating time, energy, reputation, and political capital. The myth of “having it all,” shows that even high-performing women must make explicit prioritizations, often accompanied by visible sacrifices that shape how they are perceived. Sponsorship, not just mentorship, plays a critical role in opening doors. It also highlights that organizational culture matters more than policy, and it reveals how identity and leadership are deeply intertwined, with women often navigating a narrower band of acceptable behaviors.

The bigger picture for me is that I can define success on my own terms. Success extends beyond title or compensation, and without open dialogue about ambition, flexibility, and life stages, organizations risk losing talented leaders.”
Laura Rodriguez, Cornell University (Johnson)

“The most impactful case I encountered was my very first one, in Leading in a Complex World, taught by Aaron “Ronnie” Chatterji. We analyzed Pasqal, a French quantum computing startup, as it debated whether to expand its partnership with the Kingdom of Saudi Arabia. The case was not about financial modeling or deducing the single “correct” answer; it centered on geopolitical risk, ethical considerations, and long-term strategic tradeoffs. As new MBA students working in our C-LEAD (our learning groups for core courses) for the first time, we quickly realized how difficult it is to synthesize diverse viewpoints under time pressure. Our discussion was nuanced and, at times, conflicting. Integrating those perspectives into a coherent recommendation within an hour forced us to confront an uncomfortable truth: complex strategic decisions rarely yield consensus or certainty.

Effective leadership is about structuring disagreement, surfacing tradeoffs, and aligning a group around a defensible path forward. This case taught me the importance of setting clear group norms, ensuring balanced participation, and embracing compromise without diluting rigor – skills that shaped how I approached subsequent team engagements at Fuqua and will continue to guide me professionally.”
Dan Crair, Duke University (Fuqua)

“One of the most impactful cases for me was PharmaSim, a multi-year marketing simulation where we managed a cold medicine brand in a competitive over-the-counter market. Instead of analyzing a static case, we had to make real decisions each round on pricing, advertising, product positioning, and distribution while competing against other teams.

The biggest lesson was how interconnected every decision is. A pricing change affects demand, which impacts production, retailer relationships, and brand perception. Early on, it was easy to focus on one lever, like advertising or price, but the simulation made it clear that strong performance comes from aligning the entire strategy across product, promotion, price, and channel. It reinforced that marketing is not just creative messaging. It is a series of disciplined strategic choices, backed by data, where small misalignments across decisions compound quickly in a competitive market.”
