    Professionalism, Fiduciary Duty, and Health-Related Business Leadership

    By: Joshua D. Margolis

    Expanding fiduciary duty to leaders of health-related businesses can help leaders meet the challenges of caring for not only the corporation and shareholders but also the patients and medical professionals. How should leaders of health-related businesses weigh the demand for efficiency and profit alongside the care of patients and the professional development of physicians? How might physicians approach these leadership roles to withstand the pressures that can divert behavior away from the espoused purposes and ethical standards of medicine?

    How the Other Fukushima Plant Survived

    By: Ranjay Gulati, Charles Casto and Charlotte Krontiris

    In March 2011, Japan's Fukushima Daiichi nuclear power plant was devastated by three reactor explosions and two core meltdowns in the days following a 9.0 earthquake and a tsunami that produced waves as high as 17 meters. The world is familiar with Daiichi's fate; less well known is the crisis at its sister plant, Daini, about 10 kilometers to the south. As a result of nature's onslaught, three of Daini's four reactors lacked sufficient power to achieve cooldown. To prevent the disaster experienced up north, the site superintendent, Naohiro Masuda, and his team had to connect them to the plant's surviving power sources. In a volatile environment, Masuda and Daini's hundreds of employees responded to each unexpected event in turn. Luck played a part, but so did smart leadership and sensemaking. Until the last reactor went into cold shutdown, Masuda's team took nothing for granted. With each new problem they encountered, it recalibrated, iteratively creating continuity and restoring order. Daini survived the crisis without an explosion or a meltdown.

    The Transparency Trap

    By: Ethan Bernstein

    To get people to be more creative and productive, managers increase transparency with open workspaces and access to real-time data. But less transparent work environments can yield more-transparent employees. Employees perform better when they can try out new ideas and approaches within certain zones of privacy. Organizations allow them to do that by drawing four types of boundaries: around teams of people (zones of attention), between feedback and evaluation (zones of judgment), between decision rights and improvement rights (zones of slack), and for set periods of experimentation (zones of time). By balancing transparency and privacy, organizations can encourage just the right amount of "deviance" to foster innovative behavior and boost productivity.

    Power and Influence in Society

    By: Julie Battilana

    This module aims to help students understand how power and influence are employed, both to reproduce the status quo and to effect change in society. It first helps them to understand why, more often than not, power is used to reproduce the existing way individuals and organizations operate in society. It then highlights what it takes to implement societal change. This includes a wide variety of initiatives ranging from attempts to change individuals' and organizations' behaviors in a given industry or sector, to efforts to change behaviors throughout a country, region, or even the world. Addressing the issue of power and influence in society in an MBA classroom is critical, especially at a time like now, when the relationship between business and society is attracting increasing attention, and when business leaders are increasingly expected to contribute not only to financial value creation, but also to social value creation. In this context, it is important to prepare business school students to lead not just in their organizations, but more broadly in society. Meeting this aspiration requires equipping them with knowledge and tools that will enable them to understand what it takes to have a positive impact in the world. In line with this objective, this module note focuses on how leaders who are not part of government or other public agencies can spark, organize, and/or guide action to bring about change at the societal level.

Leadership Initiative

The Leadership Initiative undertakes cutting-edge research and course development projects about leadership and leadership development, both within HBS and through collaborations with other organizations.
Leadership

As our world grows increasingly global, intricate, and ever-changing, the role of leaders is becoming more and more complex and critical to business success. In the 1950s and 1960s, Fritz Roethlisberger and Elton Mayo's contributions to the "Hawthorne effect," and work by Paul Lawrence and Jay Lorsch on organizational integration, sparked the field of Organizational Behavior. Early work by Michael Beer on leading organizational change, Rosabeth Kanter on innovation for productivity, John Kotter on power and influence, and Michael Tushman on innovation management helped shape today's understanding of organizational transformation. With an interest in Leadership that spans our academic units, our approach to research is collaborative and multi-disciplinary. We leverage a wide range of research methodologies – from onsite field research to surveys, experiments, and extensive longitudinal studies.

Chobani: Growing a Live and Active Culture In-Class Multimedia Case

By: Joshua D. Margolis, Ruth Page and Matthew Preble
  • May 2026 |
  • Case |
  • Faculty Research
Pre-abstract: In-class multimedia cases are designed to unfold in the classroom. The student-facing Prep for In-Class Case should be assigned to students before class. The instructor-facing In-Class Multimedia Case should be used by the instructor in class to facilitate discussion. Some in-class cases include Additional Materials, which can be used in class or shared with students after class. Some cases have instructor-facing Case Updates, which typically contain case reveals. Abstract: Hamdi Ulukaya, CEO of the Greek yogurt company Chobani, Inc., was reflecting on what explained his young company's meteoric rise. The company held over half of the U.S. Greek yogurt market, and nearly 20% of the total yogurt market. The company's innovative approach to product design, sales, marketing, and communication had made its yogurt a hit with consumers, and its entrepreneurial and innovative culture made it popular with its employees. But by 2012, major food companies, such as General Mills and Groupe Danone among others, were beginning to aggressively promote their Greek yogurt. In addition, Chobani was rolling out innovative new products, and had to determine how to enter new markets. At the same time, Ulukaya was also focused on preserving the company's unique culture and approach to work as it grew.

'In That Crucible, You Find Innovation': Public Safety Transformation in Albuquerque (Abridged)

By: Amy C. Edmondson, Hise O. Gibson, Antonio Manuel Oftelie and Stacy Straaberg
  • May 2026 |
  • Case |
  • Faculty Research
In summer 2020, Albuquerque, New Mexico Mayor Tim Keller faced multiple city issues including an understaffed police force that had strained relationships with communities of color; anti-racism protests; and high rates of crime, gun violence (including police shootings), drug trafficking, and homelessness. In discussing initiatives to improve public safety, Keller’s leadership team decided to create Albuquerque Community Safety (ACS), an independent, cabinet-level agency and third branch of the 911 dispatch system (alongside the police and fire departments). ACS deployed behavioral health and social services professionals to address mental health, substance use, and other issues. The agency aimed to not only improve emergency response and access to social services but also alleviate pressure on the police and fire departments, which regularly received calls for assistance with mental health and other matters outside their expertise.

By October 2023, ACS had grown in headcount and budget. It had taken close to 50,000 calls, diverting about 31,000 from the police department, which helped free up officers to do their core work as indicated by an increase in homicides solved. However, the city still ranked high in homicides and police killings, which The New Yorker covered in a high-profile story that prompted questions about ACS’s value. Nonetheless, Keller and many other leaders were hopeful about the future of public safety in Albuquerque. What helped or hindered the creation of ACS? And what could ACS teach Keller about what he should pursue next to transform public safety and public health in Albuquerque?

How Fast-Growing Companies Can Make Better Decisions

By: Tatiana Sandino
  • May 8, 2026 |
  • Article |
  • Harvard Business Review Digital Articles
Fast-growing companies inevitably hit a decision-making breaking point. What begins as founder-led, informal control fractures as organizations scale—typically along predictable fault lines: alignment, operational complexity, financial discipline, and oversight. Leaders then face a familiar but false choice: centralize decisions to restore control or decentralize to preserve agility. Both approaches fail. Over-centralization stifles frontline judgment and responsiveness; over-decentralization leads to inconsistency, inefficiency, and strategic drift. The solution is a third path: structured empowerment. This approach combines the discipline of standardization with the flexibility of local autonomy. Leaders define a limited set of curated options—drawn from best practices—for how work can be done, while holding employees accountable for results rather than compliance with process. Frontline employees retain the freedom to choose the option that best fits local conditions, but within a system that captures and scales what works. To implement it, leaders must identify the risks in their current decision model, design focused option sets, and build supporting systems for learning and feedback. The goal is not to choose between control and autonomy, but to integrate them—creating organizations that are both consistent and adaptive at scale.

Mentorship and Mobility at Walmart

By: Summer R. Jackson and James I. Cash
  • April 2026 (Revised May 2026) |
  • Case |
  • Faculty Research
In the spring of 2024, Jerry Geisler, executive vice president and chief information security officer (CISO) for Walmart, learned that his deputy Rob Duhart was leaving for a new role as CISO of the cloud services division at a leading technology company. Geisler and Duhart had a close professional and personal relationship, and had discussed the offer candidly. While Geisler recognized that this was an attractive career opportunity for Duhart, he was disappointed to lose someone he had viewed as a potential successor. Having now seen two successive deputies depart Walmart for external offers, Geisler took this opportunity to reflect on his recruitment and retention practices. This case provides students with authentic perspectives directly from the leaders involved, encouraging empathy, critical thinking, and personal reflection. By hearing from both Geisler and Duhart, students gain insight into the dynamics of leadership, trust, and career navigation. The case invites students to reflect on a fundamental paradox of leadership development: when we do it well, our people sometimes outgrow us. The case unpacks how to develop our own career path, how to develop the career paths of others, and how to foster developmental relationships within a dynamic organizational environment.

Ann Le Cam: A Career Bridging Creativity, Technology and Business in Entertainment

  • Faculty Research
In March 2026, studio and talent leader Ann Le Cam was hiking one of her favorite trails above Los Angeles, reflecting on a three decade career spent at the intersection of creativity, technology, and business. After helping lead Walt Disney Animation Studios through a profound digital and cultural transformation and, later, rebuilding culture and production support at Wētā FX in New Zealand, she had deliberately stepped away from in house executive roles in 2022 to advise companies and leaders on how to build environments where creative people could feel safe enough to do the hard work of innovation. Now Stability AI’s CEO, Prem Akkaraju—who had previously recruited her to Wētā—was asking her to come inside once again, this time to lead people related functions in a generative AI company at the forefront of technology, creativity, and talent development. As she looks out over the city, Le Cam must decide whether to remain an independent advisor shaping the wider entertainment ecosystem from the outside or apply her experience internally and guide Stability AI through the next wave of AI informed transformation.

IBM: Arvind Krishna and the Unlocking of Potential

  • Case |
  • Faculty Research
In early 2020, Arvind Krishna became the CEO of IBM, a hundred-year-old technology company that had become risk-averse. A technologist by training, Krishna was not most analysts’ choice for the next CEO of IBM. This case examines how, over the next six years, Krishna reoriented IBM’s portfolio, managed spinoffs and acquisitions, and more than tripled the stock price. It requires students to consider leadership style, long-term strategy, ongoing shifts in the tech sector, and the proper balance of research and monetization.

Joe Mazzulla and the Boston Celtics (A) (Abridged)

By: Linda A. Hill, James I. Cash and Lydia Begag
  • April 2026 |
  • Case |
  • Faculty Research
Joe Mazzulla's leadership journey with the Boston Celtics began in 2016 when he served as an assistant coach for their NBA G-League affiliate. In 2019, he was promoted to a "behind-the-bench" assistant coaching role with the Celtics, before being asked to become the interim head coach in September 2022 following the suspension of the head coach. All throughout the 2022-2023 NBA season, Mazzulla discovered the demands of the role, learning what his players and coaching staff needed from him as well as how to manage relationships with the Boston sports fanbase and the media. Despite the Celtics falling short in the 2023 NBA Eastern Conference Finals, Mazzulla used the offseason to recalibrate and refine his leadership and communication strategies for the upcoming 2023-2024 season.
By June 2024, Mazzulla's hard work and evolution had paid off, with the Celtics reaching the NBA Finals for the second time in three years. As Game 4 of the Finals approaches (with the Celtics being up 3-0), Mazzulla finds himself at a crossroads, contemplating his pre-game message to the team. Should he rally them with an aggressive “go for the kill” mindset, or choose language that is more aligned with their “joyous intensity” culture? Mazzulla knows his rhetoric matters and how he communicates could determine if the franchise secures their 18th championship or not.

Hope, Money, Love: Growing Impact at LIFT

By: David L. Ager and Antonio M. Oftelie
  • April 2026 |
  • Case |
  • Faculty Research
As Michelle Rhone-Collins took the helm as CEO of LIFT, a nonprofit social enterprise that aimed to break the cycle of generational poverty in the United States, she aspired to grow LIFT’s outcomes by transforming its service model and reaching more of the six million American families with young children living in poverty.

Rhone-Collins recognized that renewing LIFT’s purpose and approach would be a delicate process. Since 1998, the organization had evolved to a direct-service model that centered its work on the people it served and endeavored to improve members’ family well-being, financial strength, and social capital through its secret sauce of “hope, money, and love.” What’s more, LIFT supported this work through a loving, uplifting culture that prized humility, learning, and inclusive decision-making. As Rhone-Collins became CEO in 2019, she had to drive innovation in LIFT’s services without disrupting the human-centered approach that underpinned its work.

As Rhone-Collins sought to lead LIFT’s efforts and discover this balance, she and her leadership team were wrestling with difficult questions. Among them: How could they craft a vision to innovate and accelerate LIFT’s work while preserving the qualities that made it successful? What organizational and cultural capabilities would LIFT have to develop? How should they pace change and help staff, members, and funders make sense of the transformation? Most fundamentally, was it feasible for an organization that prized people and direct service to grow its impact while preserving a human touch?
