With the virtual presentations there is a lot more what can go wrong from a technical point of view. Having your internet connection that gets disrupted may cause to quickly end your presentation.
As part of your presentation for a virtual presentation, also think about back-up scenarios. Is there another presenter who can take over from you if you get disconnected? Does somebody else also have your presentation slides to take over? Do you also have the ability to connect to the webcast by mobile phone as a backup solution? Preparing for technical issues in advance may avoid problems. You wouldn’t be the first to discover that internet worked perfectly all day and suddenly stopped working for a sometime when you had to present.
