In April 2013, Ron Johnson (HBS '84) stepped down after just 18 months as CEO of J.C. Penney.

Eight women had first enrolled in Harvard Business School's traditional MBA program in 1963. By 2013, the number of women in the MBA classroom had reached 40%. The 50th anniversary of women's enrollment in the traditional MBA program gave HBS Dean Nitin Nohria the opportunity to take stock of the progress that had been made by HBS women students and alumnae and ponder what still remained to be done. The case examines the evolving experiences of male and female MBAs over the decades through interviews with dozens of HBS alumni, as well as the experiences of female faculty at the School. The case scrutinizes a number of issues facing professional women, such as changing definitions of success and diversity, barriers faced by women at work, the expectations of work and family, and present-day implications for the pipeline of future women leaders. Students consider the role of the School in addressing disparities both on campus and in the wider business world.

Since its inception, London-based private equity firm Greighton Partners had managed over $15 billion in investor capital. The firm employed about 150 professionals around the globe and had completed over 175 company acquisitions since its founding. Started with a small intimate team in London, the firm had merged with a continental PE firm and was successful, with an increased focus on Asia deals. After a long day of global partner meetings behind them, a group of Greighton partners, eager to unwind, gathered to discuss the firm's success in terms of executing on its recently refined strategy. Opinions ranged across the following strategic issues: growing the firm's Asian footprint versus remaining focused in Europe; aiming to be a top performing mid-market firm or focusing on moving up a tier to compete for bigger deals against larger firms; growth and expansion through organic growth, merger/acquisition, or through lateral hires; and finally, sector mix and client mix/client focus.

At the end of their day-long partners' retreat, several firm partners discuss the challenges they face as they juggle three roles in their business life: deal makers in their own sectors; managers of younger associates and directors across their sector teams; and as leaders in their young but successful firm.

In mid-2005, Intel is examining its options for where to locate its next assembly and test plant. On its short list of potential sites includes locations in China, India, Thailand, and Vietnam.

Since the creation of the first videogame systems in the 1970s, the videogame industry has undergone numerous transformations as new technologies and market entrants fundamentally changed the gaming experience of customers. In the early 21st century, customers began accessing games without the use of a physical gaming console, either through their mobile devices, or increasingly, through the "cloud" where customers could play videogames through specially enabled devices without the need for a physical game console or game disk. How might the cloud impact the dynamics of the industry?

In 2001, Allianz Capital Partners and Goldman Sachs acquired a majority stake in Messer Griesheim, a European industrial gas concern held by Hoechst. The dealmakers faced several challenges, including delicate corporate governance issues due to partial family ownership and a consolidating market for industrial gases. Aiming to make Messer Griesheim a more attractive potential acquisition, Messer Griesheim management had drawn up a restructuring plan as early as 2000. By late 2003 the private equity players were ready to exit and the Messer family agitated for further control. Several factors were in play: the family had a buy-back option, the window of which was quickly closing; there were few possible strategic buyers, given the anti-trust issues facing a European player interested in buying the firm; and the family made no secret of its desire to retain a piece of the firm at the very least and some measure of control. The case explores the the steps taken by the private equity investors to restructure the firm, and the relationship the partners forged with the family owners, to bring about a favorable exit for the private equity partners and ownership for the Messer family. The case explores the steps taken by private equity investors to restructure a European industrial gas concern held by Hoechts, and complicated by partial family ownership. The case considers the relationship the partners forged with the family owners to bring about a favorable exit for the private equity partners and ownership for the Messer family.

In 2010, the U.S. retail market value for next-generation non-handset wirelessly-enabled devices was just over $1 billion. By 2011 it had grown 1,141% to $13.2 billion and was forecast to reach $24.7 billion in 2015. At the same time, user demand for data was surging with the popularity of mobile Internet, e-mail, and messaging, which left carriers scrambling to increase network capacity. To capture more revenue in the data market, AT&T formed the Emerging Devices Organization (EDO) in 2008 as a distinct internal initiative to identify and partner with manufacturers developing the next generation of mobile broadband devices - from eReaders to tablets, to implanted medical devices, to supply-chain tracking devices, to dog collars and many more. AT&T executives believed that these partnerships would position the company for its next "winning play," following the path it blazed in 2007 with Apple for the iPhone. The EDO was run by Glenn Lurie, who had led the team that partnered with Apple. He knew from experience that to capture the market with the next game-changing device, his team would need to develop a new partnership model, both inside AT&T and with the ecosystem of partners who were poised to lead the global mobile broadband revolution. Doing so within a company the size of AT&T would be tough, but Lurie believed his group was up to the task.

Yoga, an ancient discipline, has become popular worldwide. The marketing of yoga and dispute over its origins have led to debate as to whether yoga should be branded at all. Some yoga instructors have gone so far as to copyright their varieties of yoga; others in the yoga community say it is a religious and/or spiritual practice and as such should not be claimed as intellectual property.

Chanel, the iconic haute couture house, founded by Gabrielle "Coco" Chanel in 1913, came to embody its founder's philosophy, taste, and style and set a distinctive and influential tone for women's fashion. Coming to prominence during the height of cultural modernity in the 1920s and 1930s, Chanel's designs wrapped high and low cultural references into beautiful yet practical clothing and jewelry for women of Europe and the Americas. In their articulation of clean, classic lines, her designs set a standard for women's fashion and clothing, relevant from 1910 through to the 1960s. She created several iconic but understated staples of many women's wardrobes, such as her signature cardigan and suit, the quilted handbag with a chain-link strap, which left its wearer's hands free, and "the little black dress," all of which continue to be part of women's wardrobes today in some shape and form. Chanel died in 1971 leaving the future of the brand and its leadership uncertain.
