Findings don't have to be earth-shattering to be useful. In fact, obvious insights can help you overcome three barriers to change in your organization: resistance to new data ("But that's not what my experience has shown"), resistance to change itself ("But that's the way we've always done it"), and organizational uniqueness bias ("That will never work here"). You can also gain trust by confirming what people already believe.

Sheryl Sandberg's life seemed ideal--she had a great job, a best-selling book, a loving family. But in the spring of 2015, her husband was felled by a cardiac condition while the couple was vacationing in Mexico. Struggling to regain her footing after his death, she reached out to her friend Adam Grant, a Wharton professor and author, to explore what research tells us about resilience. That led to their collaboration on the newly published book "Option B: Facing Adversity, Building Resilience, and Finding Joy." In this edited interview with HBR editor in chief Adi Ignatius, Sandberg and Grant share what they learned about developing resilience in yourself, your team, and your organization. They discuss how to respond when a colleague suffers a loss ("Acknowledge that there is a ginormous elephant sitting in the room"), how to grow not just in the wake of tragedy but before it, and ways that individuals and organizations can "fail well" and adapt to changing circumstances and unforeseen crises. "The best thing you can do is build routines that might be applicable in an unexpected situation," they say.

Collaboration is taking over the workplace. According to data collected by the authors over the past two decades, the time spent by managers and employees in collaborative activities has ballooned by 50% or more. There is much to applaud about these developments-but when consumption of a valuable resource spikes that dramatically, it should also give us pause. At many companies, people spend around 80% of their time in meetings or answering colleagues' requests, leaving little time for all the critical work they must complete on their own. What's more, research the authors have done across more than 300 organizations shows that the apportionment of collaborative work is often extremely lopsided. In most cases, 20% to 35% of value-added collaborations come from only 3% to 5% of employees. The avalanche of demands for input or advice, access to resources, or sometimes just presence in a meeting causes performance to suffer. Employees take assignments home, and soon burnout and turnover become real risks. Leaders must start to manage collaboration more effectively in two ways: (1) by mapping the supply and demand in their organizations and redistributing the work more evenly among employees, and (2) by incentivizing people to collaborate more efficiently.
