Since the start of the 21st century, a new breed of shareholder--the activist hedge fund--has frequently played a decisive role in interactions between corporations and markets. The game of these activists is simple: They buy stocks they view as undervalued and pressure management to do things they believe will raise the value, such as giving more cash back to shareholders or shedding divisions that the activists think are driving down the stock price. With increasing frequency they get deeply involved in governance--demanding board seats, replacing CEOs, and advocating specific business strategies. The authors have identified six ways in which to fend off activist challenges or use them to improve your organization: (1) Have a clear strategic focus and stick to it. (2) Analyze your business as an activist would. (3) Have your external advisers lined up in advance and familiar with your company. (4) Build board chemistry. (5) Perform in the short run against declared goals. (6) Don't dismiss activist ideas out of hand.

Omar Ishrak, Medtronic's first non-American CEO, aims to reinvigorate the medical device maker's growth by focusing on emerging markets, therapy innovation, and creative business models. In 2012, budget constraints in mature economies, the lack of new medical therapies coming to market, and the decline in growth of Medtronic's core businesses has reduced the company's once dynamic growth close to zero. As the newly appointed CEO, Ishrak faces the formidable challenge of restoring the company's growth. In his first 18 months as CEO, he has laid the groundwork for future growth by ramping up R&D investment in breakthrough therapy innovations. To bolster Medtronic's near-term prospects, he has supported creative product and business model innovations aimed at overcoming adoption barriers in emerging economies. Ishrak restructured his executive team and their responsibilities: the heads of Medtronic's global operating regions and major countries, who previously reported to the head of international, now report directly to the CEO, putting seven non-Americans on the excecutive committee. In another important milestone, Medtronic acquired a Chinese orthopedics company, which became its first fully integrated business unit outside the U.S. Ishrak is trying to decide whether these steps are sufficient to transform Medtronic from a multinational into a truly global company and restore its growth.

The former Medtronic CEO and current Professor of Management Practice at Harvard describes the importance of following your True North and explains why he refers to the past 10 years as "leadership's lost decade". He describes five types of leaders that often lose sight of their True North and get derailed. He also talks about the importance of leading an "integrated life" and shows that authentic leadership entails a transition from 'I' to 'we'.

Daniel Kim was considering blowing the whistle on his friend, the CEO of a fast-growing start-up where Kim had spent most of his professional career. When Kim joined the company, called Cardio-Metric, in 2002, it consisted of seven young engineers (including its two 25-year-old founders) working from a one-bedroom Minneapolis apartment. By 2008, when the venture capital-backed company recorded $110 million in revenues, Kim had become close friends with the founders, who served as CEO and chairman. Cardio-Metric's success, however, concealed troubling internal developments. Since 2002, the CEO's management style had progressed from unconventional to questionable to egregious. Kim, Cardio-Metric's on-and-off CFO, had repeatedly confronted the CEO over his behavior-including charging large purchases with no clear business purpose to Cardio-Metric and presenting unrealistic financial projections to investors-but the CEO dismissed Kim's concerns and ordered him not to share them with others at the company. By April 2009, Kim believed the problem had grown out of control, and he was considering disclosing the CEO's actions to the board of directors and a team of external auditors. There was much at stake. Kim's disclosure would undoubtedly ruin his friendship with the CEO, endanger Kim's own role at the company, and even jeopardize the future of Cardio-Metric itself.

The ongoing problems in business leadership over the past five years have underscored the need for a new kind of leader in the twenty-first century: the authentic leader. Author Bill George, a Harvard Business School professor and the former chairman and CEO of Medtronic, and his colleagues, conducted the largest leadership development study ever undertaken. They interviewed 125 business leaders from different racial, religious, national, and socioeconomic backgrounds to understand how leaders become and remain authentic. Their interviews showed that you do not have to be born with any particular characteristics or traits to lead. You also do not have to be at the top of your organization. Anyone can learn to be an authentic leader. The journey begins with leaders understanding their life stories. Authentic leaders frame their stories in ways that allow them to see themselves not as passive observers but as individuals who learn from their experiences. These leaders make time to examine their experiences and to reflect on them, and in doing so they grow as individuals and as leaders. Authentic leaders also work hard at developing self-awareness through persistent and often courageous self-exploration. Denial can be the greatest hurdle that leaders face in becoming self-aware, but authentic leaders ask for, and listen to, honest feedback. They also use formal and informal support networks to help them stay grounded and lead integrated lives. The authors argue that achieving business results over a sustained period of time is the ultimate mark of authentic leadership. It may be possible to drive short-term outcomes without being authentic, but authentic leadership is the only way to create long-term results.
