Baidu launched in 2000 as a search engine platform. Two decades later, it’s become one of the few companies in the world that offers a full AI stack. Its core businesses span mobile, cloud, intelligent driving and other growth initiatives, and its products and services have attracted hundreds of millions of users and hundreds of thousands of enterprise customers.

Imagine you’re leading a small organization, but you’re struggling to recruit and afford the senior talent you need to grow. You could hire a part-time executive. So-called “fractional leadership” is common in startups and is spreading to other businesses and nonprofits. But while a fast-growing number of senior leaders seek this work arrangement, many companies are unsure of how to go about it. Tomoko Yokoi and Amy Bonsall are experts on the practice. Yokoi is a researcher at the TONOMUS Global Center for Digital and AI Transformation at IMD Business School. Bonsall is a former executive at IDEO and Old Navy who works as a part-time chief product officer with several organizations. They explain when and how fractional leadership works best—for the individual as well as the organization—and how to do it right. Yokoi and Bonsall wrote the HBR article “How Part-Time Senior Leaders Can Help Your Business.”

Around the world, the past few years have been marked by increasing political polarization and public outrage. Like it or not, this spills over into the business world, with employees, customers, and shareholders more willing than ever to challenge companies -- and one another -- on a range of issues.

Drawing on his work with government officials and corporate executives, he walks us through the root causes of our current crisis, explains how to effectively navigate through disagreement, and offers practical takeaways for managers at every level. Ramanna is the author of the book The Age of Outrage: How to Lead in a Polarized World.

We live in an age of data. But having powerful tools to gather employee feedback doesn't mean you’ll get powerful results. It’s challenging for executives to turn that feedback into substantive action. New research from Ethan Burris, professor of management at the McCombs School of Business at the University of Texas at Austin, sheds light on how to weed through all the data, make sure workers feel heard, and turn employee insights into real results. Burris is a coauthor of the HBR article "What Companies Get Wrong About the Employee Experience."

Unwelcome employee turnover can create big problems for managers, teams, and organizations, so it's important to understand the real drivers of attrition. New research from Ethan Bernstein, associate professor at Harvard Business School, and Michael Horn, cofounder of the Clayton Christensen Institute, points to a host of push and pull forces that cause workers to jump ship and also outlines better retention strategies. They are the coauthors, along with Bob Moesta, of the HBR article "Why Employees Quit" and the book Job Moves: 9 Steps for Making Progress in Your Career.

There was a time when business leaders and managers didn't worry so much about psychology or other social science research. Malcolm Gladwell's writing played a big role in changing that. His popular exploration of tipping points — the phenomenon where small, incremental actions can suddenly fuse into a full-blown social behavior — brought research insights to life and made them mainstream. Now he's revisiting tipping points, this time looking at how they can be used for damaging results. In this episode, HBR editor in chief Adi Ignatius speaks to Gladwell about how the author’s ideas have changed, the importance of social science and journalism in today's world of virality, and the unexpected ways leaders should consider human behavior. Gladwell is the author of the new book Revenge of the Tipping Point: Overstories, Superspreaders, and the Rise of Social Engineering.
