In 2006, Sophia Amoruso started Nasty Gal, an eBay boutique selling vintage clothes. With a strong sense of style and personality, Amoruso poured herself into building the brand and developing relationships with her customers - typically the slightly edgy 18-24 year old. The company had grown since that time into a multi-category retailer, expanding into third party clothing, accessories and its own private label. Its explosive growth was one of the biggest stories in e-commerce, especially when the retailer attracted $50m in investment from Index Ventures, a top VC firm that funded other successful retailers such as Net-a-Porter and Etsy, in 2013. Yet, with a cash infusion, plans for a brick and mortar store, an ever-growing e-commerce site, and fierce competition, Amoruso wondered what opportunity to tackle next. Should she concentrate on product line expansion into lingerie, swimwear, cosmetics and fragrances? How would a brick and mortar store impact the focus of the company or its ability to develop customized web sites for overseas markets? How would she maintain the detail and attention she had put into so many aspects of the company as Nasty Gal grew? As Sophia's time was limited and management resources were already spread thin to sustain the existing site's growth, what was the best way forward?

Miranda Cresswell, marketing director, and Greg Marsh, founder and CEO of onefinestay, were grappling with branding and positioning dilemmas. onefinestay offered high-end home rentals to travelers who sought a more authentic and local experience than a typical upscale hotel might provide. onefinestay's brand had been "hacked" together quickly during the company's early years. After five years of rapid growth, Marsh brought Cresswell on board to do a comprehensive analysis of the company's brand and its positioning in the marketplace. Cresswell had spent several months gathering data and insights, and was starting to experiment with use case scenarios that took a crack at segmenting the company's customers. The preliminary results were interesting, but raised more questions than they answered, and Cresswell wondered if this was the best way to segment the market. While segmenting in this way was intriguing, it led to a branding challenge-as a start-up, it was difficult for onefinestay to have the resources to support multiple brand messages in the marketplace and different segments wanted different things from their travel experience. She pondered whether there were other ways to group customers that would allow for a more universal positioning for the brand or whether the company needed to focus on one or two segments to serve. Positioning the fledgling brand was a challenge. Who was the company competing against and how could it carve out a unique value proposition that would appeal to travelers and be differentiated from what was offered by other hospitality options? Was its current moniker "the unhotel" working for or against it?

In December 2013 a group of angry protesters blocked one of the commuter bus provided by the large Silicon Valley firms (known as "Google buses") which was stopped in San Francisco on its way to the company's headquarters 40 miles south. The protests were a tangible manifestation of the sharp increase in tensions between citizens upset with changes they saw in San Francisco and the "techies" and technology companies they held responsible for the disappearing middle class, increased homelessness, languishing public education, and a sense of departure from the unique culture and values of the city's past. This case explores some of the substantial economic inequality problems facing San Francisco, and how much responsibility for creating or exacerbating the problems rests with the government, technology firms, their employees, and the nature of capitalism, among others. It also allows for discussion of what technology firms and the "techies" might do to help alleviate the problem.

After several years of near steady state, the market share of Colgate Palmolive Canada Inc. in the toothpaste category has gathered momentum in 2012. In a bid to extend the gap between the company and its primary competitors in the category in 2013, the vice-president of customer development is discussing the options with his team at company headquarters in Toronto. Market share is an important performance metric at the company. One suggestion is to increase the marketing budget. There is a general consensus that marketing dollars should not be diffused across activities during the year, but there are differences of opinion about what to focus on - trade promotions, consumer promotions or advertising - in order to sustain the momentum in market share in 2013.

Global consumption of petroleum products stood at just more than 90 million barrels per day by the end of 2013, and was expected to increase to 91 million or more by the end of 2014. Petroleum companies were constantly exploring the planet for new oil reserves to meet this voracious demand for fossil fuels. Because three-quarters of the earth was water, it was evident that these oil reserves were largely underwater; however, until the end of 2013, very few players had explored this opportunity. Although reaching deep-water drilling sites posed various challenges - environmental, political, technological, etc. - offshore exploration was the future of the oil and gas industry.Because of its very successful campaigns, Cairn India was ideally positioned for offshore exploration. Capturing and capitalizing on the opportunity of offshore exploration would give it an edge, but the question remained: Would it be better to gain the prime mover advantage or wait for other players to start the process so that it could learn from others' mistakes and reap benefits later?

In November of 2010, the board of Stanford Hospital and Clinics announced that Amir Dan Rubin, at the time chief operating officer of the UCLA Hospital System, would become the next CEO at Stanford Hospital and Clinics. Although by 2010 Stanford hospital had largely recovered from a failed merger with the hospital of the University of California, San Francisco, and was financially stable, Rubin would lead an organization that still faced significant challenges. These included creating a focus on patient care and improving operational performance, especially in the wake of an increasingly competitive health system landscape. Rubin's success depended on obtaining the support of a large existing internal staff as well as the medical center faculty. The faculty reported to the dean of the medical school, not to Rubin. The case describes what Rubin did to transform the culture and operations of Stanford Health Care and, specifically, what he did to build support among the various constituencies so critical to his being successful: the medical school physicians, the board of the hospital, and the colleagues already at Stanford. The case also looks at the next steps that Rubin planned in 2014 for continuing to move the hospital forward and the challenges with which he would need to grapple. The case is useful in classes on leadership, organizational culture and culture change, and in classes on power and influence where outside succession and the task of building internal support is a topic.

After identifying a need in the market for a simpler way to manage prenatal nutrition, three Darden classmates develop an idea for a subscription e-commerce business that provides a monthly box of nutritionist-approved prenatal snacks, recipes, personal care products, and information for expectant mothers. To determine the best name for their product, the women run Google AdWords campaigns and choose the one that performed best. But was this the right decision, or should they rerun the test with the two best-performing names? And was this the most important business decision they needed to make at this point, or were there more pressing matters to address?

It is January 2014, and the case protagonist, David Milestone (senior advisor at the Center for Accelerating Innovation and Impact at the U.S. Agency for International Development's Global Health Bureau), is preparing for a meeting of global stakeholders and pharmaceutical manufacturers who are interested in reducing mortality caused by childhood pneumonia and are prepared to donate $10 million to support this effort. Milestone's goal is to propose a strategy to address childhood pneumonia in Uganda, toward which the $10 million donation would go. In addition to effectively and sustainably reducing childhood pneumonia deaths, the plan must align the interests of various stakeholders behind the problem. A successful strategy in Uganda could be a model for interventions elsewhere. The United Nations Commission on Lifesaving Commodities for Women and Children recently identified Uganda as a "pathfinder" country, meaning it could serve as the example for other countries wrestling with the same issues. This is a remarkable opportunity to change the lives of children in Uganda-and all around the world.

In October 2008, in the midst of a financial crisis, Anthony Keating, investment manager at the Boston private bank Billingsley, Blaylock, and Montgomery, was searching for an investment strategy to recommend to his high-net-worth clients. Traditional investments in the equity markets were being decimated, and Keating's clients would be looking to him for ideas. Inspired by the success of Paulson and Co., Keating began to explore the possibility of entering a trade that would profit as homeowners defaulted on their mortgages. The more Keating learned about the trade, the more he realized that he needed to know about mortgage-backed securities and credit default swaps. The case provides instructors with a chance to introduce these financial instruments while providing lessons applicable to students interested in value investing or real estate finance.

On the evening of June 10, 2011, the first European tour of Korean idol groups was held in Paris. With European fans demanding tickets and organizing a flashmob rally in front of the Louvre Museum, SM Entertainment, the producers, immediately set up an additional European concert. The success of the Paris concert elevated the status of K-pop and showed that it held potential in the global market. Behind the development of K-pop was the unique production system created by Soo-man Lee of SM Entertainment. When he established SM Entertainment in 1995, Lee introduced a systematic production system that integrated the functions of record distribution, agency, and management and enabled the company to make long-term investments in talented artists. The adoption of a sustainable growth model led SM to emerge as the leader in the Korean entertainment industry. This case explores in depth SM Entertainment's talent development process. It also traces the successes and failures that SM experienced, primarily in China, Japan, and Korea and discusses Lee's vision of building a "virtual nation." Lee believed that "the world's biggest star would come from the largest market," thus explaining his focus on succeeding in the Chinese market and grooming Chinese talent. The case concludes by examining a number of strategies that SM Entertainment used to develop a presence in the global music market.

Funding to scale Citizens Connect, Boston's 311 app, is both a blessing and a burden and tests two public entrepreneurs. In 2012, the Commonwealth of Massachusetts provides Boston's Mayor's Office of New Urban Mechanics with a grant to scale Citizens Connect across the state. The money gives two co-creators of Citizens Connect, Chris Osgood and Nigel Jacob, a chance to grow their vision for citizen-engaged governance and civic innovation, but it also requires that the two City of Boston leaders sit on a formal selection committee that pits their original partner, Connected Bits, against another player that might meet the specific requirements for delivering a statewide version. The selection and scaling process raise questions beyond just which partner to choose. What would happen to the Citizens Connect brand as Osgood and Jacob's product spread across the state? Who could help scale their work best then nationally? Which business models were best positioned to drive that growth? What intellectual property arrangements would best enable it? And what role should the two city employees have, anyway, in scaling Citizens Connect outside of Boston in the first place? These questions hung in the air as they pondered the one big one about passing over Connected Bits for another partner: should they?

In 2012, Syngenta, one of the world's largest agricultural input company, committed to build a $1 billion business in Africa over the next 10 years. In mid-2014, CEO Michael Mack and Africa Venture Team head Dimitri Pauwels are reviewing progress. Was the company's committment to Africa still relevant and achievable?

Argentina-based Cresud managed 1 million hectares (2.5 million acres) of land in South America. For 20 years, the publicly traded company's strategy had been to acquire underutilized properties and turn them into productive farmland for cattle and crops. In 2014, Cresud's CEO wondered if the strategy was still correct in the face of falling commodity prices, more powerful input companies, and potentially positive changes in Argentina's political environment.

In 2005, Teruo Yabe is asked to revive Tessei, the 669-person JR-East subsidiary responsible for cleaning its Shinkansen (""bullet"") trains. Operational mistakes, customer complaints, safety issues, and employee turnover are at or near all-time highs, even as the demands on Tessei continued to grow. Given previous leaders' failed attempts to fix Tessei's problems with increased managerial monitoring and controls, Yabe seeks a creative approach to overcome the motivation, capability, and coordination challenges facing his organization. Like many contemporary leaders, he selects transparency as his tool. He is, however, unique in adopting a highly nuanced approach to implementing transparency. In the process, he not only leads a fantastic organizational turnaround but even helps to make otherwise ""dirty"" work more meaningful for Tessei front-line employees. The case therefore presents students, particularly in leadership, organizational behavior, operations management, and service operations courses, with an opportunity to think through how a well-crafted transparency strategy can act as a powerful leadership tool.

The protagonists of the case are CEO Kenneth Frazier and Roger Perlmutter, president of research, as they contemplate Merck's future in light of a difficult external environment and multiple internal challenges. Overall, the pharmaceutical industry faces the threat of patent expirations, diminishing new drug breakthroughs, adverse regulatory laws, increasing competition, and a harsh economic climate. With its new drug pipeline running dry, Merck accepted that the biotech industry is too complicated for it to navigate alone. As it stood, it was producing only 1 percent of the biomedical research in the world. Thousands of new ideas were emerging around the world, both inside and outside of the company. While Merck had been moving toward an open innovation strategy, its stellar history of internal research and development had created a culture resilient to working externally. Should Merck pursue an open innovation strategy? If so, how? Another issue that the case deals with is executing corporate strategy via acquisitions of smaller biotech companies such as Merck's recent acquisition of Idenix.

Sarah would soon graduate from Stanford GSB, and had received entry-level job offers from a number of wealth management firms. A tech-savvy Millennial, she wanted a career that would provide both intellectual challenges and a healthy work/life balance. She had five job lucrative offers to evaluate, and needed to weigh her options carefully. This case describes a hypothetical scenario of a student deciding which wealth management firm is the best fit for her interests, work style, and long-term career goals. The case provides a comprehensive overview of five distinctly different types of wealth management firms, with business models ranging from a traditional private bank with portfolio teams that sold the bank's products to clients, to an investment firm that delivered institutional-quality management to private clients, to a new venture using a technology-driven model designed to replace individual advisers entirely. The business model and fee structure of each type of firm are discussed in detail, along with additional insights into how the firms operate.

A publisher with a history of aiming at ignored or underserved markets is about to launch a series of micro e-books whose central character, El Diablo, is a gangster with a flamboyant lifestyle. The target audience is young men of the inner city. A prominent member of the Institute for African-Americans in the Media objects--loudly. The publisher's head of marketing and new product development must decide whether projected profits from the series outweigh the likely backlash and possible risk to the company's reputation. Expert commentary comes from John Morayniss, CEO of Entertainment One Television, and Michelle Rice, executive vice president of affiliate sales and marketing at TV One.
