What should you think about in the planning process before creating a virtual event?

It’s much the same process as a live event.  Start with a blank sheet of paper decide what you need to achieve. You may have a single creative thought/idea and you can build a good spectrum of content around that.  Think about how you can deliver value, what is the scope of audience and who might your guests/speakers be. What other assets could you use, the type of engagement or interaction you want.  Think about risk & contingency planning.
