Once the speaker is selected, there is no special preparation required.
Follow the direction of the speaker. If there are no special requirements you can setup the room as a circle of chairs for smaller events with less than 20 people or rows of chairs (auditorium seating) for larger events.
Welcome the guests to the event. Take a few moments to introduce the speaker and their topic. Set expectations for the audience by sharing the expected duration of the talk and associated Q/A time.
Share any slides, photos, or videos from the event. Remember to invite them to join the Business Agility Institute.
