Some other things to consider here that will be in our ITPro Playbook which will release soon:
1. Speaker preparation - Ensure your speakers have good connectivity and audio devices. For our recent large scale event at Microsoft we allowed certain speakers to upgrade their home equipment (headsets) to ensure good quality.
2. Dry run - Every great event producer does a dry run especially if you haven't done a life event before. Get used to switching what your audience is seeing from speaker to speaker or to presentation view.
3. Moderation - It is usually advisable for a large Live Event to have someone else handling moderation so your core producer can focus on quality and visual content. Getting familiar with the producer/presenter chat as well as the Q&A module is essential to having the conversation feel dynamic as it would in a standard meeting.
Best Practice: In my invitations I always use a short URL service to wrap the attendee Event link. That way in case of any disruption we can easily reroute an audience. Trust me.. it's worth the effort!
Multiple Live Events happen every day, now more than ever, and its an important component in your communications plan. You can ask your questions here or bring additional questions about designing virtual events with all the tools you have at your disposal in PubSec to the Driving Adoption community. The first version of our playbook is available here at https://aka.ms/O365ChampionResources. We covered this topic in our March community call. Both the deck and recording are available in the community. Thank you.
