With COVD-19 forcing widespread adoption of virtual communication for much of the world, some wonder if these remote business practices will become the norm. Before the pandemic, international business travel was a 1-point-5 trillion-dollar annual expense – an expense that’s increasing about 7-percent a year. Why have corporations been willing to absorb this cost when technologies such as Skype, FaceTime, Zoom, WebEx, etc., have been widely available for the better part of a decade? Growth Lab researchers have been studying this question for years. You see, the Growth Lab’s approach to development puts particular emphasis on knowhow. We're not talking about the information that exists in bo oks, computer files, graphs and algorithms. Knowhow only exists in brains, and it was very slowly from brain to brain through years of on the job, learning and interacting with experience counts. So to move knownow, you have to move brains. Now for more on the importance of moving knowhow, its relevance to business travel and some findings in our research, let's bring in our guests.
