Rita McGrath, professor at Columbia Business School, says the need for organizations to adopt digital business models is more important than ever. Change is accelerating as startups tackle incumbents. And suddenly the coronavirus crisis is forcing the hand of many companies that have put off digital transformations. She explains how established firms can avoid bet-the-farm moves and instead take small steps and quickly target their experiments. McGrath is the coauthor of the HBR article "Discovery-Driven Digital Transformation."

Vivek Murthy, former U.S. Surgeon General, says that, even before the Covid-19 pandemic, we were facing another health crisis: loneliness. Studies show that, around the world, more people have been feeling a greater sense of social isolation, which has many negative affects, including increased blood pressure, reduced immune response, and decreased engagement and productivity at work. But organizations can be a place where people find a greater sense of belonging. Murthy wants us to take loneliness more seriously and focus on fostering the types of authentic connections -- face-to-face and virtual -- that we need to combat it. He's the author of the book "Together: The Healing Power of Human Connection in a Sometimes Lonely World."

Eric McNulty, associate director of Harvard’s National Preparedness Leadership Initiative, studies how managers successfully lead their companies through crises such as the Deepwater Horizon oil disaster and the Boston Marathon terror attack. He identifies the common traps that leaders fall into and shares how the best ones excel by thinking longer-term and trusting their teams with operational details. He also finds that companies that put people ahead of the bottom line tend to weather these storms better. McNulty is a coauthor of the book “You’re It: Crisis, Change, and How to Lead When It Matters Most” and the HBR article “Are You Leading Through Crisis… Or Managing the Response?”

Alex Lazarow, venture capitalist at Cathay Innovation, says that start-ups in cities around the U.S. and the world are creating their own rules for success. While Silicon Valley companies have sparked key innovations and generated huge wealth over the past few decades, not everyone should use them as a model going forward. In fact, we can learn more from frontier entrepreneurs, who are thinking more creatively about raising capital, sourcing talent, and pursuing social impact. Lazarow is the author of the book "Out-Innovate: How Global Entrepreneurs--from Delhi to Detroit--Are Rewriting the Rules of Silicon Valley."

Stewart Friedman, organizational psychologist at The Wharton School, and Alyssa Westring, associate professor at DePaul University’s Driehaus College of Business, say it’s a mistake for a working parent to think of career and home life as competing interests that have to be balanced. Their research shows how many leadership skills apply to parenting, and vice versa. The professors explain how individuals can stop making tradeoffs and instead find sustainable ways to advance their careers and also parent more effectively. Friedman and Westring are the authors of the book "Parents Who Lead: The Leadership Approach You Need to Parent with Purpose, Fuel Your Career, and Create a Richer Life."

In 1976, broadcast journalist Oprah Winfrey moved to Baltimore to coanchor the evening newscast at a local TV station. But she struggled in that spot and was moved to the morning talk show. That demotion led Winfrey to discover a professional calling that aligned with her personal sensibilities and emerging strengths. In the final episode of a four-part special series on leadership, HBR Editor in Chief Adi Ignatius and Harvard Business School professor and historian Nancy Koehn trace Winfrey’s career as an entrepreneur and leader of a media empire. They discover lessons on how to cultivate self-awareness, cross traditional boundaries, and responsibly wield influence.

Tsedal Neeley, a professor at Harvard Business School, says that there are simple ways leaders can help their employees stay productive, focused, and psychologically healthy as they work from home during the current global pandemic. The right technology tools and clear and constant communication are more important than ever. She recommends that managers do an official remote-work launch, carefully plan and facilitate virtual meetings, and pay extra attention to workers' behavior. For individual contributors, it's critical to maintain a routine but also embrace flexibility, especially if you're in the house with family.

Jim McKelvey, entrepreneur and cofounder of Square, says that most companies that think of themselves as innovative are really just copycats. True innovation, he argues, is about fearlessly exploring novel solutions and dramatically expanding markets. Doing so also helps startups defend their innovations against industry giants, as Square did against Amazon. McKelvey is the author of the book “The Innovation Stack: Building an Unbeatable Business One Crazy Idea at a Time.”

In 1958, writer Rachel Carson began her exhaustive research on the effects of widespread pesticide use for her next book, Silent Spring. Over the next four years, she built up an airtight case showing how the world’s most powerful chemical companies were harming animals, plants, and people. Her effort was also a race against time, as she struggled against an aggressive form of breast cancer. In the second episode of a four-part special series on leadership, HBR Editor in Chief Adi Ignatius and Harvard Business School professor and historian Nancy Koehn trace the modern environmental movement back to Carson’s pioneering reporting and powerful prose. They discover lessons in how to strengthen your resilience, gather your energy and skills for a coming challenge, and why caretaking is an act of leadership.
