Return to di original purpose
Start with di aim wey una write for event brief. If di goal na to introduce sumo culture, ask wetin participants understand or become curious about. If na guided participation, ask whether instructions and participation choices clear. No treat attendance or happy photos as proof say di wider team don improve. Useful review measure di experience wey una actually plan, so conclusions go easier to discuss with colleagues and supplier.
Ask small number of clear questions
Invite attendees to comment on preparation information, communication, cultural explanation and whether di format suit dem. Add question about wetin no clear or wetin dem fit arrange better. Ask observers and active participants, because dem fit experience programme differently. Keep feedback short enough to finish while di event still fresh. You no need long questionnaire to discover say arrival directions or clothing instructions need more attention.
Review di session and travel arrangements
Review di session itself together with transport, gathering, changing and departure arrangements, and identify who responsible for each part. This help prevent unrelated transport delay from becoming wrong judgement about instruction, or good activity from hiding coordination problem wey una fit avoid. Share relevant feedback with organiser and keep short record for future planning. Record confirmed facts and participant observations separately from your own interpretation, so di next event team get concrete thing to learn from.
