Event Design: Design the Experience, Not the Agenda
Purpose first, format second
Event design starts from purpose: what the audience should know, feel or do afterwards. Then define personas and map the attendee journey across pre-arrival, arrival, immersion, departure and follow-up. Only then choose formats that fit the intended outcome: keynote, workshop, world café, open space, site visit, structured networking. Adult learning principles (relevance, problem-centred, application, feedback) argue against pure lecture when the goal is a skill.
Physical and sensory design
Room set carries meaning: theatre for scale, rounds for discussion, classroom for note-taking, hollow square for governance. Sightlines, screen proximity, noise, light, temperature and sensory branding all shape behaviour. Accessibility and inclusion, meaning step-free routes, captioning, quiet rooms, dietary and religious needs, belong in the design brief rather than in a late compliance pass.
Traps to expect
Choosing a format before agreeing objectives; confusing decoration with design; over-scheduling and calling it value; and treating a hybrid audience as a camera pointed at the room rather than a separate experience.
Rule of thumb
If you want a different outcome, change the format. Content tells people; format makes them act.
Worked example
An objective of "attendees will co-author regional policy recommendations" cannot be met by a 45-minute panel. It requires a facilitated breakout with a pre-read, a shared drafting template, and a plenary report-back with named owners.
