Lucy Normen, Chief Operating Officer of Sweetbriar Hospital, had just gotten off the phone with her Emergency Department Director, Dr. Max Warner. He was very upset with the present situation in the ED: people currently boarding in the ED hallways because there were no open inpatient beds; some patients waiting over 24 hours to be admitted; stressed out medical staff." Dr. Warner worried about possible mistakes-and likely drops in patient satisfaction scores. Lucy was puzzled. They had just spent millions of dollars on expanding the hospital's emergency department, yet in the three months since it re-opened things had gotten worse rather than better. She had a strong feeling that her problems were all related to inefficient patient flow throughout the hospital, but didn't quite know how to address them.

This case is excellent for teaching both MBAs and executives how to create a blue ocean strategy that is hard to imitate and sustainable. It focuses on Wikipedia versus Britannica.com in the online encyclopedia industry. The case teaches participants the importance of aligning the three strategy propositions of value, profit, and people around both differentiation and low cost to break the value-cost trade-off and create a blue ocean that is hard to imitate. Compelling firsthand video interviews with Jimmy Wales, the founder of Wikipedia - along with other key executives, staff and volunteers, otherwise known as Wikipedians - bring this case to life in the classroom. It can be downloaded from https://www.blueoceanstrategy.com/teaching-materials/wikipedia/ The case is also available in Chinese.

Dr. Barrett Rollins, Chief Scientific Officer of the Dana Farber Cancer Institute, attempts to engender cross-scientist collaboration by applying project management principles to medical research. The resulting innovation, Integrative Research Centers, are novel in this field and present a substantial challenge to the Institute's culture, which had previously allowed faculty scientists complete autonomy over their research. Center leaders are required to develop a business plan, adhere to agreed-upon performance metrics, and undergo regular progress reviews conducted by a peer-led oversight committee. The Center for Nanotechnology in Cancer, a new but crucial center in the program, has failed to meet almost all of its objectives in the first year. Furthermore, a heated dispute between two faculty members in the center has complicated matters significantly. Rollins is flummoxed by these problems because he thought he had provided resources and clear objectives to all of the centers. He must urgently diagnose the main reason(s) for the center's shortcomings and develop a plan of action so that this center's problems do not undermine the whole initiative toward greater scientific collaboration.

In May 2011, Chairman Chen Yuan of the China Development Bank (CDB) was thinking back on CDB's financing of a major project between Petroleo Brasileiro SA (Petrobras), Brazil's state-owned oil and gas producer and China Petroleum & Chemical Corporation (Sinopec), one of China's largest oil companies. Signed two years earlier, the deal was an oil-for-loan agreement in which Petrobras committed to a 10-year oil supply to Sinopec in exchange for a $10 billion loan from CDB. The case study describes the deal and its importance to both countries. The case also discusses CDB's evolution from a policy bank to more of a commercial enterprise.

This case describes an IQ experiment in which 66 students, under the direction of their professor, used Excel to generate simulated IQs. The instructions were such that the generated IQs should have come from a normal distribution with a mean of 100 and standard deviation of 15. The sample average IQ, however, was 104.3. Students are asked to use their data-analysis skills to make sense of the results. The data set also contains gender (male or female) and fall section (A, B, C, D, or E) for each student, which allow for additional statistical analyses (tests of equality of means).

This short case describes a famous experiment conducted by Sir Ronald A. Fisher and colleagues to test Dr. B. Muriel Bristol's claim that she could tell-only by tasting-whether milk or tea was poured first into her cup. Using hypothesis testing, students must answer the question of how many correct picks the lady tasting tea (LTT) must make in order to "prove" her claim.

The case describes the selection of an information technology (IT) product to support the operations of 1-888-Junk-Van, a small waste-collection business based in Ontario, Canada. Marcus Kingo, the business owner, had five alternatives from which to choose, namely a database upgrade, contracting out development of a new software application, using Google Docs, using an online tool framed as Platform as a Service (PaaS), or implementing a small-business enterprise resource planning (ERP) system. Each option presents strengths and weaknesses, and students are left to make a decision. The case exemplifies the IT deployment challenges faced by small companies. The case emphasizes the general industry characteristics and the particular operational circumstances that led the owner to identify the need for IT. Such circumstances, as well as the particular features and commercial conditions of each alternative, should serve as the main background for arriving at a decision.

Porsche Canada wants to encourage their Canadian customers to drive their cars in winter. The prize is increased sales of cars (by consumers currently unwilling to buy a Porsche only for summer driving) and winter accessories, such as snow tires. This is a three-fold challenge because Canadians generally believe that luxury vehicles should not be driven in winter due to to ice and salt; that sports cars generally performed poorly in winter conditions; and it was unwise to drive a luxury car in winter where it could be more easily scratched or damaged.

Fairmount Minerals, producer of industrial sand in the United States, embarked upon a journey of sustainable development in 2005. The mining industry had an unenviable reputation that threatened the sustainability of the company. Given the strong personal values of stewardship of the planet and community held by the CEO, and because of the reputation of the industry, Fairmount Minerals was moved to action to integrate sustainable development in every step of its value chain - from mining to shipping the product to the customer. Fairmount's journey had been exciting and full of hard work and dedication to the practice of sustainable development. The three broad themes of people, planet and prosperity resonated in all facets of the company. Starting in 2006, each year the organization generated a set of bold goals and monitored its progress toward these goals. These goals clearly spelled out the benefit for the environment and the planet. The question that remained was how this benefit translated into prosperity for the stakeholders and the company. Under what conditions did this stewardship of planet and people lead to increased growth for the company?

Nintendo faced huge difficulties in July 2011. Sony's PlayStation and Microsoft's Xbox had caught up with the innovative motion-sensing controllers of the original Wii. And the new Nintendo 3DS handheld console had experienced a very disappointing start. Moreover, videogame consoles (particularly handheld ones) were facing increasing substitution from online and mobile games played on social networks and/or mobile phones (e.g. Zynga's Farmville). First, could Nintendo come up with a novel and innovative console once again (a Wii Encore) in order to escape head-to-head competition against its two larger rivals (Sony and Microsoft)? Second, how could Nintendo fend off the new substitutes, which were competing for a large portion of its customers?

Akhil Patel is passionate about his business idea: an innovative green technology fuel cell. He wants to dive in and commit to his startup, but Roopa Rao, his fiancée, is much more risk averse, his parents don't approve of the startup, and Akhil has an enticing alternative offer from a prestigious consulting firm. Should Akhil follow his dream and become an entrepreneur? Or should he acquiesce to the other forces in his life and take the "safer" consulting job? This is a companion case to Career at a Crossroad: Akhil Patel, HBS No. 812-010, giving Roopa Rao's point of view.

Hiroshi Mikitani, the CEO of Rakuten, (Japan's largest online retailer), is at the helm of an organization that is rapidly expanding into global markets. In a critical stride toward becoming the world's No. 1 Internet services company, Mikitani announces Englishnization - a highly publicized aggressive two-year English proficiency mandate for all 7,100 of Rakuten's Japanese employees. Mikitani's goal is not only to ensure the success of the organization, but also to break down linguistic and cultural boundaries in Japanese society. At the time, only an estimated 10% of the Japanese staff could function in English. The stakes are high: those who do not reach their target score by the deadline risk being demoted. As Englishnization progresses, loss of productivity, lack of time to study, and conflicted views among managers impede staff success. Some employees even question the relevance of Englishnization, particularly for staff working exclusively in Japan. Fifteen months since the announcement, the vast majority had not yet reached their target English proficiency scores. With the deadline rapidly approaching, Mikitani must decide how to proceed to ensure the success of Englishnization, the continued global rise of his organization, and even the future of Japan.

The case examines an iconic institution's decision on whether or not to undertake a branding initiative. Founded in 1802, West Point has played a key role in America's history. It is one of the nation's oldest institutions of higher learning and is well known for producing prominent military, political, and business leaders. In the increasingly competitive environment of higher education, the Director of Strategic Communications at the U.S. Military Academy is faced with a decision on whether or not to invest resources in a rebranding effort. Over the course of the school's history, several distinct logos have come into existence and little uniformity or guidance for use exists. Data from a recent consumer survey offers some insight for the decision maker to contemplate, as does the school's recent appearance on the cover of Forbes' magazine as the number one undergraduate institution in the nation. Numerous stakeholders, tradition, the competitive environment, and resource constraints all factor into the decision making process.

The case explores a deicing capacity expansion decision made by JetBlue at Boston Logan International Airport in the summer of 2010. The need for capacity expansion was driven by significant challenges faced during the previous winter combined with substantial scheduled growth for the upcoming winter.

In early May 2011, Daphne Zohar, founder and managing partner of PureTech Ventures, a life science venture creation company in Boston, MA, was reviewing a term sheet she had just received from a venture capital (VC) firm for one of PureTech's portfolio companies. The term sheet was due to expire in a week, but through negotiations of term sheet items, PureTech could probably leave the discussions with the venture firm open for another month. PureTech had a unique position in the life sciences ecosystem. It aimed to tackle important medical needs by translating scientific innovations into commercially viable technologies, and in order to do that optimally, was structured as an operating company that created start-ups rather than a typical venture fund that simply invested in them. The VC term sheet Zohar was considering outlined a Series A funding round for one of PureTech's newly created companies. Meanwhile, Zohar's team was also in discussions with several large pharmaceutical companies that were interested in partnering or even acquiring the company. These discussions were progressing nicely but would not lead to a transaction by the due date set by the VC term sheet (or an additional month from then). The current situation presented her with a unique challenge. Should PureTech accept the "bird in hand" VC term sheet or turn it down and wait for the negotiations with the pharmaceutical companies to play out? The latter route offered the potential for a desirable, near-term partnership, but risked that the negotiations would fall through, in which case PureTech would end up losing both time and the opportunity for near-term external validation of its portfolio company.

The case details the conflict between Mike Mayo, an influential banking analyst, and Citigroup about what Mayo considers aggressive accounting policies. Mike Mayo questions Citigroup's lack of a valuation allowance against its deferred tax assets despite Citi's recent losses. The case discusses the economics of and accounting for deferred tax assets. It also focuses on management-analyst relations and challenges faced by analysts in providing a negative opinion on companies. The inclusion of deferred tax assets in Tier 1 capital and implications for regulatory capital are also discussed.

Dr. Edson Bueno created Amil, Brazil's largest health insurer. Unlike many others, it is vertically integrated. Dr. Bueno has two opportunities for growth. Which, if any, should he pursue?

This case study explores how Tan Siok Siok, a Singaporean filmmaker living in Beijing, crowd-sources the content, financing, and distribution outlets for her documentary about Twitter, using the micro-blogging platform itself. Crowdsourcing, according to professor of journalism, Jeff Howe, is "the act of taking a job traditionally performed by a designated agent, usually an employee, and outsourcing it to an undefined, generally large group of people in the form of an open call." The Twittamentary website was launches in August 2009 with an invitation to "share a great story that answers the question: what is the most interesting thing that happened to you because of Twitter?" Twitter users from around the globe volunteer their anecdotes to shape the final story and also provide the resources to finance and distribute the film.

In less than two years, the founders' innovative model for addressing last-mile challenges in an online grocery retailing operation was working. Although still consuming cash, the three-month-old pilot expansion to another city was experiencing three-digit monthly sales growth. To date, the company had followed a philosophy of low-cost experimentation, as it explored terrain that had been inhospitable to its predecessors. But now Relay needed to make some changes in its operations strategy.

In mid 2010 the Sealed Air Corporation has to decide on next steps for its novel video tracking technology (called VTID) after unsuccessful attempts to market it in three different industry settings. The company must determine whether its most recent target market, the quick-serve restaurant segment, is still worth pursuing or whether the company should look for a different application and market altogether. The company could also revisit the previous two applications, tracking and tracing processed meat and tracking employee safety practices. At the other extreme, after seven years of R&D and marketing efforts and millions of dollars in expenses, the company could cease attempts to commercialize VTID.
