Presentation decks of any size and purpose benefit from a clear structure with divider slides between sections. This gives the audience orientation. This applies even more so to readers of a presentation document, who do not have a presenter in person walking them through the document's logic. Maybe you have already noticed that most presentation files of the large management consulting firms use agendas to structure both presentation and back up slides?
The Agenda Helper saves time and effort while making your content easier accessible to your audience.
