In 2015, Apple debuted the iPhone 6S, which employed a default encryption system preventing both Apple and government authorities from accessing data stored on the device. But since then, global governments have questioned whether Apple’s desire to protect customer privacy interferes with public health and safety. Harvard Business School senior lecturer Henry McGee and professor Nien-hê Hsieh discuss how Apple CEO Tim Cook manages this tension.

Ethanol had already transformed Brazil, where flex-fuel vehicles dominated the streets. Raízen, a bioenergy company headquartered in São Paulo, sought to prove that second-generation ethanol (E2G) could do the same for the world – especially in hard to decarbonize sectors, such as aviation and shipping. E2G is made from a byproduct of sugarcane that doesn’t compete with food production, Paula Kovarsky, Raízen’s chief strategy and sustainability officer, was confident the company could become a global green energy champion. But she faced a complex challenge: how to expand the market for second-generation ethanol and other sugar-cane waste biofuels, in order to ensure Raízen’s long-term growth.

In December of 2020, SolarWinds learned that they had fallen victim to a widespread malware supply chain attack. This attack granted hackers access to thousands of it customers’ data, including military and government agencies across the globe. General Counsel Jason Bliss needed to orchestrate the company’s response without knowing how many of its 300,000 customers had been affected, or how severely. What’s more, the existing CEO was scheduled to step down and incoming CEO Sudhakar Ramakrishna had yet to come on board. In this episode of Cold Call, Professor Frank Nagle discusses SolarWinds’ response to this unprecedented supply chain attack and the case, “SolarWinds Confronts SUNBURST.”

Should businesses take a stand for or against particular societal issues? And how should leaders determine when and how to engage on these sensitive matters? Harvard Business School senior lecturer Hubert Joly, who led the electronics retailer Best Buy for almost a decade, discusses examples of corporate leaders who had to determine whether and how to engage with humanitarian crises, geopolitical conflict, racial justice, climate change, and more in the case, “Deciding When to Engage on Societal Issues.”

When Ferrari, the Italian luxury sports car manufacturer, committed to achieving carbon neutrality and to electrifying a large part of its car fleet, investors and employees applauded the new strategy. But among the company’s suppliers, the reaction was mixed. Many were nervous about how this shift would affect their bottom lines. Harvard Business School professor Raffaella Sadun and Ferrari CEO Benedetto Vigna discuss how Ferrari collaborated with suppliers to work toward achieving the company’s goal. They also explore how sustainability can be a catalyst for innovation.

Which sales candidate is a startup’s ideal first hire? What marketing channels are best to invest in? How aggressively should an executive team align sales with customer success? Harvard Business School senior lecturer Mark Roberge discusses how early-stage founders, sales leaders, and marketing executives can address these challenges as they grow their ventures in the case, “Entrepreneurial Sales and Marketing Vignettes.”

In 2017, Tommy Hilfiger launched its adaptive fashion line to provide fashion apparel that aims to make dressing easier. By 2020, it was still a relatively unknown line in the U.S. and the Tommy Hilfiger team was continuing to learn more about how to serve these new customers.  Should the team make adaptive clothing available beyond the U.S., or is a global expansion premature?

In December 2020, Delta Air Lines CEO Ed Bastian and his leadership team were reviewing the decision to join the OneTen coalition, where he and 36 other CEOs committed to recruiting, hiring, training, and advancing one million Black Americans over the next ten years into family-sustaining jobs. But, how do you ensure everyone has equal access to opportunity within an organization?

In August 2022, the Pentagon tasked Victor Lopez, then a captain in the U.S. Air Force, with launching a new Air Force innovation unit that leveraged commercial developers and military talent to acquire advanced technologies. It’s often believed that only small start-up organizations can innovate, but a lot of innovation happens in big organizations, including government. Harvard Business School assistant professor Maria Roche is joined by Major Lopez to discuss the challenges of digital transformation in a large bureaucratic organization.

Entrepreneur Wendy Estrella is attempting to simultaneously scale her law practice, as well as her property management and development company. What strategy will benefit both businesses, and is there a downside to scaling them together, rather than focusing on each one separately?

On June 9, 2022, the first LIV Golf event teed off outside of London. The new tour offered players larger prizes, more flexibility, and ambitions to attract new fans to the sport. Immediately following the official start of that tournament, the PGA Tour announced that all 17 PGA Tour players participating in the LIV Golf event were suspended and ineligible to compete in PGA Tour events. Eventually, LIV Golf filed an antitrust lawsuit accusing the PGA Tour of anticompetitive practices, and the Department of Justice launched an investigation. Then, in a dramatic turn of events, LIV Golf and the PGA Tour announced that they were merging. Harvard Business School assistant professor Alexander MacKay discusses whether or not the PGA Tour took the right actions in response to LIV Golf’s entry.

Launched in 2016, Proximie was a platform that enabled clinicians, proctors, and medical device company personnel to be virtually present in operating rooms, where they would use mixed reality and digital audio and visual tools to communicate with, mentor, assist, and observe those performing medical procedures. The goal was to improve patient outcomes. The company had grown quickly, and was now entering strategic partnerships to broaden its reach.

When serial entrepreneur Martine Rothblatt (founder of Sirius XM) received her seven-year-old daughter’s diagnosis of Pulmonary Arterial Hypertension (PAH), she created United Therapeutics and developed a drug to save her life. When her daughter later needed a lung transplant, Rothblatt decided to take what she saw as the logical next step: manufacturing organs for transplantation. Rothblatt’s entrepreneurial career exemplifies a larger debate around the role of the firm in creating solutions for society’s problems. If companies are uniquely good at innovating, what voice should society have in governing the new technologies that firms create?

Bhagwan Mahaveer Viklang Sahayata Samiti (BMVSS) is an Indian nonprofit famous for creating low-cost prosthetics, like the Jaipur Foot and the Stanford-Jaipur Knee.

To kick off the week-long celebration, the show’s producers have each picked their three favorite episodes from the archives for listeners to revisit.

Headquartered in Kitengela, Kenya, Sian Flowers exports roses to Europe. Because cut flowers have a limited shelf life and consumers want them to retain their appearance for as long as possible, Sian and its distributors used international air cargo to transport them to Amsterdam, where they were sold at auction and trucked to markets across Europe. But when the Covid-19 pandemic caused huge increases in shipping costs, Sian launched experiments to ship roses by ocean using refrigerated containers. The company reduced its costs and cut its carbon emissions, but is a flower that travels halfway around the world truly a “low-carbon rose”?

In mid-2022, many automakers were announcing deadlines by which they would stop selling ICE vehicles altogether, buoyed by investment analysts and favorable press. While this would reduce tail-pipe emissions, it ignored the fact that the production of EVs—and especially their batteries—increases emissions in the supply chain. BMW decided to focus on lifecycle emissions and pursued a flexible powertrain strategy by offering vehicles with several options: gasoline and diesel-fueled ICE, plug-in hybrid electric vehicles, and battery electric vehicles. But that approach received a frostier reception in the stock market. Can BMW convince stakeholders that its strategy is good for the environment and the company’s financial performance?

The Spatial Monitoring and Reporting Tool (SMART) was created by a coalition of conservation organizations to take historical data and create geospatial mapping tools that enable more efficient deployment of park rangers to prevent poaching. SMART had demonstrated significant improvements in patrol coverage, with some observed reductions in poaching. Then a new analytic tool, the Protection Assistant for Wildlife Security (PAWS), was created to use artificial intelligence (AI) and machine learning (ML) to try to predict where poachers would be likely to strike. Jonathan Palmer, Executive Director of Conservation Technology for the Wildlife Conservation Society, already had a good data analytics tool to help park rangers manage their patrols. Would adding an AI- and ML-based tool improve outcomes or introduce new problems?

Muhammad Ali, born Cassius Marcellus Clay Jr, rose from a poor family in segregated Louisville, Kentucky to international fame, winning three heavyweight boxing titles and becoming a civil rights leader and role model for millions of people around the world.

In 2013, soon after the U.S. Securities and Exchange Commission (SEC) had started a massive whistleblowing program with the potential for large monetary rewards, two employees of a U.S. bank’s asset management business debated whether to blow the whistle on their employer after completing an internal review that revealed undisclosed conflicts of interest. Should they escalate the issue internally or report their findings to the U.S. Securities and Exchange Commission? Harvard Business School associate professor Jonas Heese discusses the potential risks and rewards of whistleblowing.

For years, Airbnb gave hosts discretion to accept or reject a guest after seeing little more than a name and a picture, believing that eliminating anonymity was the best way for the company to build trust. But after research provided evidence that Black hosts received less in rent than hosts of other races and showed signs of discrimination against guests with African American sounding names, the company had to decide what changes to make. Should they change the design of the platform to reduce discrimination? And what’s the best way to measure the success of any changes?

In February 2022, Russia invaded Ukraine, and multinational companies began pulling out of Russia, in response. At Switzerland-based Nestlé, chief executive Mark Schneider had a difficult decision to make. Nestlé had a long tradition of neutrality that enabled it to operate in countries regardless of their political systems and human rights policies. But more recently the company had embraced Michael Porter’s “shared value” paradigm, which argues that companies have a responsibility to improve the business community and the health of their communities. What should Schneider do?

Wordle went from a personal game, created by a developer for his girlfriend, to a global phenomenon with two million users in just a few months. Then The New York Times made an unexpected bid to acquire it. But will Wordle outlast other pandemic pastimes?

In May 2022, the Seoul Metropolitan Government in Seoul, South Korea, launched the pilot of Metaverse Seoul, a virtual version of Seoul’s mayor’s office. As they worked towards building a broad, immersive, online government platform, they hoped to gain insights from citizens about everything from popular local tourist sites that could be experienced virtually to government services that could be delivered in the metaverse. But to do that, the team had to figure out how to solicit ideas from citizens and then determine which ideas to put to use.

In January 2022, Microsoft announced its acquisition of the video game company Activision Blizzard for $68.7 billion. The deal would make Microsoft the world’s third largest video game company, but it also exposes the company to several risks. First, the all-cash deal would require Microsoft to use a large portion of its cash reserves. Second, the acquisition was announced as Activision Blizzard faced gender pay disparity and sexual harassment allegations. That opened Microsoft up to potential reputational damage, employee turnover, and lost sales. Do the potential benefits of the acquisition outweigh the risks for Microsoft and its shareholders?

Sylvia’s Restaurant, which celebrated its 60th anniversary in August 2022, is a testament to the values instilled by the founder and matriarch, Sylvia Woods. She cultivated a strong community around her soul food restaurant in New York City’s Harlem neighborhood that has continued to thrive, even after her passing a decade ago. Amid business expansions and succession planning, the legacy of Sylvia Woods continues to live on. But as Sylvia’s grandson takes over the business, a new challenge faces him and his family: what should the next 60 years of Sylvia’s look like?

Marie Curie, born Maria Sklodowska from a poor family in Poland, rose to the pinnacle of scientific fame in the early years of the twentieth century, winning the Nobel Prize twice in the fields of physics and chemistry. At the time, women were simply not accepted in scientific fields. So Curie had to overcome enormous obstacles in order to earn a doctorate at the Sorbonne and perform her pathbreaking research on radioactive materials. How did she plan her time and navigate her life choices to leave a lasting impact on the world?

In late 2013, Ryan Cohen, cofounder and then-CEO of online pet products retailer Chewy.com, was facing a decision that could determine his company’s future. Cohen was convinced that achieving scale would be essential to making the business work and he worried that the company’s third-party logistics provider (3PL) may not be able to scale with Chewy.com’s projected growth or maintain the company’s performance standards for service quality and fulfillment. But neither he nor his cofounders had any experience managing logistics, and the company’s board members were pressuring him to leave order fulfillment to the 3PL. What should Cohen do?

Asset management firm Capital SAFI wanted to attract new strategic investors and expand to other countries beyond Bolivia. Founder, chairman and CEO Jorge Quintanilla Nielsen knew that having the right corporate governance in place was critical to achieve this goal.

In 2014, Larry Fink started writing letters to the leaders of some of the largest publicly listed companies, urging them to consider the importance of environmental, social, and governance (ESG) issues. Fink is the chairman and CEO of BlackRock, one of the largest asset management houses in the world. The firm’s success was rooted in its cost-effective, passive investment products that rely on tracking indices and funds. But Fink wanted his firm to engage with the companies in which they invest and hold them accountable for their social and environmental impacts. What role should investors play in urging business leaders to take ESG issues more seriously and enforcing compliance?

In 2020, Kwame Spearman made the career-shifting decision to leave a New York City-based consulting job to return to his hometown of Denver, Colorado, and take over an iconic independent bookstore, The Tattered Cover.

But he also had to find a way to meet the big challenges facing independent booksellers amid technological change and shifting business models.

Captain Michael Davidson, of the container ship SS El Faro, was determined to make his planned shipping trip on time—but a hurricane was approaching his intended path. To succeed, Davidson and his fellow officers had to plot a course to avoid the storm in the face of conflicting weather reports from multiple sources and differing opinions among the officers about what to do. Over the 36-hour voyage, tensions rose as the ship got closer and closer to the storm. When the ship ultimately sunk on October 1, 2015, it was the deadliest American shipping disaster in decades. But who was to blame for the tragedy and what can we learn from it?

Dr. Timnit Gebru was the co-lead of Google’s Ethical AI research team –until she raised concerns about bias in the company’s large language models and was forced out in 2020. Her departure sent shockwaves through the AI and tech community ad raised fundamental questions about how companies safeguard against bias in their own AI. Should in-house ethics research continue to be led by researchers who best understand the technology, or must ethics and bias be monitored by more objective researchers who aren’t employed by companies?

Bombas was started in 2013 with a dual mission: to deliver quality socks and donate much-needed footwear to people living in shelters. By 2021, it had become one of America's most visible buy-one-give-one companies, with over $250 million in annual revenue and 50 million pairs of socks donated. As Bombas continued expanding, the company struggled to determine what pace of growth would best allow it to reach new customers while maintaining its social mission.

At the height of the pandemic in 2020, US Foods struggled, as restaurant and school closures reduced demand for foodservice distribution. The situation improved after the return of indoor dining and in-person learning, but an industry-wide shortage of truck drivers and warehouse staff hampered the foodservice distributor’s post-pandemic recovery. That left CEO Pietro Satriano to determine the best strategy to attract and retain essential workers, even as he was tasked with expanding the wholesale grocery store chain (CHEF’STORE) that US Foods launched during the pandemic lockdown.

Esusu launched in 2018 with a rotational savings product and continued growing their fintech startup in late 2019 with Esusu Rent, a rent reporting tool that enables renters to improve their credit scores. In March 2020, co-founders Abbey Wemimo and Samir Goel were working to determine how best to scale Esusu to advance their mission of promoting financial inclusion in the U.S. Harvard Business School assistant professor Emily Williams discusses how the two co-founders decided how to allocate resources and scale their business.

In the wake of George Floyd’s killing and widespread protests for social justice in the United States, OneTen was formed by a coalition of 40 large companies to address the disparity in job opportunities for African-Americans without four-year college degrees. Their goal was to provide one million jobs in 10 years. But in order to do that, OneTen had to analyze the underlying problems and formulate recommendations for both system-level problems and those that manifest themselves at an organizational level.

Corruption is as old as humanity, with cases documented as far back as the Egyptian dynasties. While the World Bank estimates that international bribery exceeds $1.5 trillion annually, the larger and more subtle effects of corruption on economies and populations is incalculable. Harvard Business School professors Geoff Jones and Tarun Khanna explore how corruption uniquely affects business in emerging markets, and why it should be addressed by the public and private sectors.

Recruit Holdings, an advertising media, staffing, and business support conglomerate was founded in Japan in 1960 by Hiromasa Ezoe. The company was built on the principle that the company should add value to society. But in 1988, Recruit hit rough waters when Ezoe sold 2.8 million shares in a subsidiary before it went public to 76 Japanese leaders in politics, business, and media. The "Recruit Scandal," as it was called, resulted in the resignation of Japan’s prime minister and his entire cabinet. Thirty years later, Recruit has become a global conglomerate, with $16 billion in sales in 2017. How did the company not only survive, but thrive after its insider trading scandal?

TikTok’s parent company, ByteDance, was launched in 2012 around the simple idea of helping users entertain themselves on their smartphones while on the Beijing Subway. By May 2020, TikTok operated in 155 countries and had roughly one billion monthly active users, placing it in the top ranks of digital platforms globally. But the app had drawn the attention of competitors, regulators, and politicians -- especially in the U.S., where commercial success was critical to its long-term enterprise value. Would TikTok become the first “Super App” with a global footprint, or did it run the risk of becoming a supernova that shone brightly only for a passing moment?

In November 2019, Mass General Brigham (MGB) was the largest recipient of National Institutes of Health funding in the world. The Innovation Office, led by Chief Innovation Officer Chris Coburn, sought to capitalize on that funding – with the goal of commercializing research done at the hospital to generate revenue and improve patient care. But CEO Anne Klibanski and other key stakeholders had a serious concern: although women comprised approximately 40 percent of the medical researchers and physicians at MGB, the percentage of women participating in innovation activities lagged behind. Can the leadership team identify the main sources of the disparities and find the right strategy to expand and diversify MGB’s community of innovators?

Founded in 2014, Thinx, Inc. makes absorbent underwear that can be worn during menstruation. But the feminine care market had seen virtually no innovation in half a century because of the taboo against discussing the topic of menstruation. As a result, the startup was competing against large incumbents like Procter & Gamble and Johnson & Johnson. Can CEO Maria Molland lead a marketing strategy that confronts those taboos in order to bring innovation to the feminine care market?

In early 2019, global beer company Molson Coors was exploring how to enter the cannabis beverages business. At the time, cannabis had not yet been legalized in Canada. Initially the company had planned to test a few products in a small geography in Canada to see if there might be a viable market opportunity. But the team charged with developing an entry strategy recommended a more aggressive move: pulling forward $65 million to build a facility in Canada to produce cannabis beverages and seize first-mover advantage. That sudden change in direction gave then-CEO Mark Hunter pause. Should he approve the request, or push the team back to the original, more conservative plan?

The Chinese telecom giant Huawei and other Chinese telecom firms, like ZTE, had been poised to lead the globe in 5G technology—until the U.S. State Department embarked on a global campaign to challenge the market dominance of Chinese firms with the Clean Network program. Did that initiative create a new era of multilateral, democratic governance of the internet, or a “splinternet” forcing participants to choose between the U.S. and China?

In 2020, JPMorgan Chase & Co. announced a $30 billion “Commitment to Advance Racial Equity.” This included investments in housing, small businesses, and financial literacy across the U.S., as well as in diversity, equity, and inclusion initiatives within the bank.

In February 2013, US Airways announced that it would merge with American Airlines to create the world’s largest airline. During the acquisition integration process, CEO Doug Parker had to determine how best to combine the two airlines’ core systems, operating processes, and leadership teams, as well as the appropriate scope and speed of strategic changes. Harvard Business School senior lecturer David Fubini discusses how Parker approached those decisions in the case, “Merging American Airlines and US Airways.”

In August 2017, Baroo Pet Care founder and CEO Lindsay Hyde wanted to continue expanding her pet services startup to new cities. In addition to raising venture capital, she needed to consider her growth strategy. Should she continue focusing on the needs of her early adopters or start tailoring Baroo’s services to more mainstream customers? And how fast is too fast to grow? Hyde (MBA 2014) joins Harvard Business School entrepreneurship Professor Tom Eisenmann to discuss how an early false positive signal from investors set an unsustainable course for her startup.

Horst Dassler, the son of the founder of Adidas, cultivated relationships with athletes and national associations – with the aim of expanding his family’s sports apparel business. In doing so, he created the first sports sponsorships for the Olympics, and ultimately became a key force behind the commercialization of sports today. Harvard Business School professor Geoffrey Jones explores the pros and cons of the globalization and commercialization of sport in his case, spanning from the 1930s to the 1970s, “Horst Dassler, Adidas, and the Commercialization of Sport.”

In 2007, Alibaba’s Taobao became China’s leading consumer e-commerce marketplace, displacing the once dominant eBay. How did underdog Taobao do it? And will it be able to find a way to monetize its marketplace and ensure future success? Harvard Business School professor Felix Oberholzer-Gee discusses his case, “Alibaba’s Taobao,” and related strategy lessons from his new book, Better, Simpler Strategy: A Value-Based Guide to Exceptional Performance.

When Kathy Fish became Procter & Gamble’s Chief Research, Development & Innovation Officer in 2014, she was concerned that the world’s leading consumer packaged goods company had lost its capability to produce a steady stream of disruptive innovations. In addition, intensifying competition from direct-to-consumer companies convinced Fish that P&G needed to renew its value proposition to make all aspects of the consumer experience “irresistibly superior.” But making this change would require wholesale transformation from within.

But with a new mission to, “Make kids smarter, stronger, and kinder,” and a lot more innovation, it seems the opposite is in the works. Harvard Business School professor Rosabeth Moss Kanter, who wrote the case with Harvard Business School professor Ryan L. Raffaelli, talks about reversing a losing streak with new partnerships and in the process determining how to answer foundational questions like, “Who are we if we make this deal?”

What does it take to successfully lead a team to the top of the highest peak in the world? First-year students find out as they participate together in, "Everest: A Leadership and Team Simulation." Harvard Business School professor Amy Edmondson talks about the choice to use Mt.

Harvard Business School professor Regina Herzlinger discusses why this idea of paying for self-care has the potential to improve health care in the United States as well.

Germany took in a million Syrian refugees in 2015, buoyed by the knowledge that these people could contribute strongly to the country’s economy. But has it worked out as successfully as hoped? Harvard Business School professor Rebecca Henderson discusses what it takes to integrate a huge number of new people, and the role business can play.

Is it possible to retain brand value after cutting costs and services dramatically just to stay alive? The airline industry has struggled with this question for decades in the face of economic downturns, changes in market structure, and shifting clientele. Harvard Business School professor Susanna Gallani discusses one of the central lessons from her case study (co-authored with Harvard Business School professor Eva Labro), "RegionFly: Cutting Costs in the Airline Industry," that encompasses any company in any industry: the long-term focus for any leadership team has to be on not just survival, but figuring out how to come back from a rough patch to regain and even exceed market position.

IDEO’s human-centered design thinking is a systematic process used to help create new products and services. And, the best part? They are open about the process and how to adopt it. Harvard Business School professor Ryan Buell explores this process through the example of Cineplanet, the leading movie cinema chain in Peru. The company hired IDEO to help them determine how to better align their operating model with the needs of its customers. Like Buell, this case may change the way you think about thinking.

Using crowdsourcing to develop an annual list of Hollywood’s hottest unproduced screenplays, Harvard graduate Franklin Leonard took the negative term “black list” and turned it into a coveted place to be. Three films that once appeared on his Black List are nominated for a Best Picture Oscar this year. Harvard Business School professor Henry McGee, the former president of HBO Home Entertainment, explores a fascinating case about navigating the Hollywood film industry, reclaiming blackness as a positive, and taking success to the next level.

Growing up in the heart of the Confederacy, Maggie Lena Walker started work as a laundress at age nine. At the urging of her mother and mentors, she turned to education, and used it to propel her life forward -- graduating high school at 16, working as a teacher, and learning accounting. Those experiences, coupled with her strong work ethic, culminated in Walker rising to lead the Independent Order of St. Luke and found several other businesses, all of which created jobs and opportunities for many women and blacks where there had been none before. Harvard Business School professor Tony Mayo discusses Walker’s remarkable legacy of firsts, and the courage and strength it took for her to forge a path forward for herself and those she served.

In theory, most companies would love to diversify their workforce. In practice, hiring specifically to increase diversity can cause a variety of cultural problems within an organization. Harvard Business School professor Robin Ely discusses two of her cases that train a critical lens on race-based and race-blind hiring, and some of the best practices firms can employ to achieve a well-balanced staff.

For more than seven decades, Ebony Magazine has chronicled the most important African-American issues, personalities, and interests of its time, including operating essentially as the journal of record for the Civil Rights Movement. But along with most other media companies, the publication faced stark challenges if it was to survive in the rapidly changing media landscape of 2015. Harvard Business School professor Steve Rogers discusses Ebony Magazine’s storied history, including its founder’s awareness of disruption theory fifty years ahead of time, and what the company has long meant for the black community.

Research says that people imprint on music in their dating years, and carry those tastes with them through the rest of their lives. Lately, this has spelled trouble for jazz music, which is failing to attract new and younger fans in a competitive musical landscape. With its listenership in steep decline, jazz legend Wynton Marsalis is looking to rebrand the genre and engineer its comeback, with the help of Harvard Business School professor Rohit Deshpande.

One third of the U.S. population is obese, even as 50 million Americans often struggle to find enough to eat. And all that in a country where 40% of the food made and purchased each year is thrown away, and in which food needs are expected to more than double over the next few decades. Harvard Business School professor Jose Alvarez discusses how the former president of Trader Joe’s is boiling these difficult problems down into one elegant solution in a pilot store in Dorchester, Massachusetts, and blazing a trail toward sustainability in the process.

There is a joke in the cybersecurity community that there are two kinds of companies: those that know they’ve been hacked, and those that haven’t found out yet. The Target Corporation learned this the hard way during the busy holiday season of 2013, when 110 million customers’ information was compromised. Harvard Business School professor Suraj Srinivasan explores one of the largest cyber breaches in history, analyzing why failures happen, who should be held accountable, and how preventing them is both a technical problem and a matter of organizational design.

Wayfair has been around since the early days of ecommerce. But where it now exists as a single, popular brand, it was once an unaffiliated collection of 240 websites selling very different things. Harvard Business School professor Thales Teixeira takes listeners on a journey through the rise of internet sales and search engine marketing, and into the minds of the company’s executives as they built an online furniture giant from scratch.

On the internet, content may be king, but connecting users is the key to building an empire. The Norwegian media giant Schibsted learned this lesson the hard way, and then used it to thrive in an online news market where many others have failed. Through the lens of his new book, The Content Trap, Harvard Business School professor Bharat Anand discusses Schibsted’s resounding success, how bringing users together drives revenue, and the importance of media companies adopting a “digital-first” approach.

By some accounts, only 5-6% of people around the world get the cardiac treatment they need to survive. The rest perish. This statistic highlights the stark need for affordable, quality health care that can be delivered at scale, and a solution to that staggering problem has sprung up in, of all places, the Cayman Islands. Harvard Business School professor Tarun Khanna explains how a new hospital with a revolutionary cost structure and service model is making a name for itself on an island better known for bright sunshine and sandy beaches.

An unfortunate but necessary part of a manager’s job is having to let underperforming employees go. Knowing when and how to take that step with the company’s, the employee’s, and your own best interests in mind is a difficult task. Harvard Business School professor Joe Badaracco discusses the best ways to make hard decisions and deliver bad news, pulling from his case “Two Tough Calls” and his new book, "Managing in the Gray."

The Affordable Care Act, or Obamacare for short, had three goals: make health insurance available, required, and affordable for everyone. There was just one problem -- the launch of the HealthCare.gov website was a complete and utter failure. Harvard Business School professor Len Schlesinger delves into the enormous challenges involved with building, launching, and fixing HealthCare.gov, and how those administrative trials and triumphs are instructive for any managerial setting.

Oktoberfest began as a raucous wedding celebration in Germany more than 200 years ago and has since grown into a worldwide phenomenon. Munich, alone, hosts some 6.4 million guests (who consume almost 8 million liters of beer) during the festival each year. Harvard Business School professor Juan Alcacer discusses how the Oktoberfest brand has been transplanted around the globe, whether copycat festivals help or hurt its reputation, and to what extent its original hosts could or should be profit-motivated.

Lego has been helping children piece together dreams and build their imaginations for decades, and has become one of the world’s most popular toys and most powerful brands in the process.

Harvard Business School professor Jan Rivkin takes listeners behind the brick and into the minds of Lego’s leadership as they tackle digital disruption, how to innovate while remaining true to their core product and mission, and engineer an impressive 2004 turnaround that positions the company for huge future success.

Before “House of Cards” was an internationally-renowned and critically acclaimed hit series, it was a total shot in the dark. Luckily for the small film studio behind it, Netflix saw it as a shot worth taking.

Most people know Apple as one of the richest and most successful companies in the world, but it wasn’t always that way. In 1997, the company suffered a near-death experience that caused it to completely reimagine itself. The result was a new line of products and a totally unique financial model that has since led to unprecedented success. Harvard Business School professor Mihir Desai explains the genius of the financial wiring behind the inventors of the Genius Bar.

It’s a good bet that winning a game show isn’t often on the list of top priorities at large companies. So how was it that building a robot to do just that became a prime focus at IBM? Harvard Business School professor Willy Shih discusses how building Watson, a deep question answering machine, reinvigorated a stalled research and development team, taught IBM a ton about communication and product development, and led to a hotly contested “Jeopardy!” match on the Harvard Business School campus.

College represents one of the biggest decisions and investments many consumers will ever make. But can they really trust the rankings available to help them choose? Harvard Business School professor Bill Kirby unpacks the complex world of university rankings, including what “world-class” actually means, what rankings don’t take into account, and how schools are learning to game an imperfect system.

A novel idea: give loyal customers a chance to buy shares in a company they love. That’s the premise behind LOYAL3, which uses the democratizing power of technology to give average investors better access to IPOs. Harvard Business School professor Luis Viceira discusses this novel mission, the huge new market it creates, and the delicate balance of being disruptive but only when necessary.

Increasingly, almost every team is a global team in some capacity. This presents a difficult challenge for managers everywhere, and especially for high-potential leaders who want to take their careers to the next level: how do you bring together a team whose members are geographically and culturally dispersed? Harvard Business School professor Tsedal Neeley discusses her case of a real-life executive charged with corralling a hugely diverse, underperforming group and leading it back to success on a global scale.

Though Google has become the U.S. face of the driverless car movement, other global companies have been developing similar technology for more than a decade.

Since brewing is a marketing-driven business, finding ways to differentiate a beverage from its competition is crucial. Heineken’s chief marketing officer took a novel approach: take the complicated processes of production and distribution and make them interesting and important to the consumer. Harvard Business School professor Forest Reinhardt explains how a big, sophisticated company used small details, from trucking routes to the color of refrigerators, to put its commitment to the environment to work on its behalf.

Entrepreneurs like Elon Musk and Jeff Bezos are tapping into their vast personal wealth to make commercial space travel a reality.

Harvard Business School professor Matthew Weinzierl discusses his new case on New Space, and how public-private partnerships are becoming the building blocks for the hottest new startup sector.

The statistics are startling: about one-third of American workers suffer from chronic work stress; $27 billion worth of work days are lost to mental health-related absences each year. Harvard Business School professor John Quelch discusses his case on the state of mental health in the U.S. workplace, and why even though companies are better than ever about providing services to their workers, the stigma attached to mental health leaves a lot of work yet to be done.

Can big companies fix big problems? Are they responsible for doing so? As the third-largest employer in the world, any move Walmart makes reverberates around the globe. Yet despite its many successes and innovations, particularly in terms of sustainability, the company often faces criticism for its business practices. Harvard Business School professor Rebecca Henderson discusses what she calls the paradigmatic case: how Walmart takes huge risks, makes great strides, and demonstrates how companies are one of the few instruments humanity has for changing the world at scale, for better or for worse.

It’s been a few months since many of us made New Year’s resolutions. Have you stuck with yours?

For entrepreneurs, size and scale don’t have to come at the cost of agility. Fabricio Bloisi, a 21-year-old Brazilian college graduate, proved that with his company Movile. Harvard Business School professor Lynda Applegate discusses how, with the right blend of talent, ambition, and teamwork, a company can become an international powerhouse and still remain nimble and true to its roots.

Research says that 85% of people will make a purchase after reading online reviews about a product or service. This has had huge implications for the hotel industry and helps explain why TripAdvisor, a massive repository of user-generated reviews, was the most-visited travel website in the world in 2013. Harvard Business School professor Thales Teixeira discusses TripAdvisor’s staggering success, how the company has forced an entire industry to change the way it considers (and purposefully influences) the online review process, and how consumers navigate that sea of reviews.

Though not everyone may know her name, Madam C.J. Walker helped invent what have become staples of our modern country and economy: national sales forces, corporate social responsibility, and, yes, even basic haircare.
