I developed this checklist of questions for designing a workshop activity. There are loads of questions one could ask and there’s a danger of over-preparing and over-analysing. So, I’d suggest, focusing on the questions which feel intuitively most relevant, which make you most creatively “restless”.
what are the aims of the activity ?
what role does the activity assume in the whole event?
why are you really doing it ?
what should participants get, as a minimum, out of the activity ?
what learning points/outcomes will be generated ?
do there need to be outcomes at all?
what kind of feedback are you looking for ?
how long will it last ?
what is the shortest time it could be squeezed to ?
how long could it take if needed ?
how much time variation is inherent in its design ?
where does it/should it come in the event timetable ?
what does it follow on from ?
what does it lead into ?
how well does it link with previous and follow up activities ?
what paper materials are needed ?
what writing materials are needed ?
what handouts are required ?
what sticking materials are needed ?
what other materials are needed ?
what room layout is needed ?
how many rooms ?
are extra chairs and tables needed ?
what equipment is needed ?
is an audio/visual sound system needed ?
what can you do without if you have to ?
how many facilitators are needed ?
what skills do they need ?
who could run this if you were unable to be there?
is pre-briefing of facilitators necessary ?
is de-briefing arranged ?
what “things” do you need?
what could go wrong ?
have you checked out the venue in advanced ?
what materials need to be pre-prepared ?
I would print this checklist off and use it on the day if you feel you need a reminder of the key elements in your chosen activity.
