Each day it seems another firm announces that they are going to keep working from home as at least an option for staff after the pandemic. It is quite likely that this will mean that virtual meetings remain the norm in the longer-term. There need only be a few participants not in a room for a video bridge to be helpful, at which point the dynamic changes from the previously normal necessity for everyone to be in on site. 

Business Development will need to adjust to the new processes, with digital solutions becoming the norm and many older analogue processes maybe never returning from their "temporary" hiatus. 

We now know that many of the processes we relied on and thought to be indispensable were astonishingly expensive and inefficient. So the good news is that even after new technologies have been deployed by firms and their Marketing and Business Development footprint is restored, there should be considerable savings available.
