Rebuild or Reboot My Business after Covid-19?

The challenge facing many businesses is unprecedented.  We are likely to have a wholesale shift in demand for long-time institutions of the past and the present.  Some businesses, as we know them, are going to evaporate.  This virus is killing businesses with as much vigor as it has people.  Tragically, some businesses have been infected and do not realize it. The question for many business leaders, as we start to reopen the economy is, do I rebuild the business or do I reboot?  Should I rebuild as it was, presuming demand will return, or reboot to something else?
