Start with a decision, not decoration
A useful event programme brief names the reader, the decision or action the page should support, and the evidence required before design begins. For this project the audience is attendees navigating a timed performance, ceremony, conference or community event. The working objective is to combine schedule, orientation and contextual information in the order attendees need it. Write those two statements at the top of the brief and test every proposed section against them. Material that does not help the reader understand, trust or act should be removed, shortened or placed in a secondary channel.
