You should now have enough ideas and guidance to at least leave you wondering about how such an event might work in your institution, and hopefully fired up enough to consider giving it a go. We would certainly urge you to do so; not least because it really is a low risk endeavour.
There are minimal costs involved and the absolute worst that can happen is that people walk out of the room at the end of the workshop little or no further forward than they were when they walked in. Whereas if it goes well you (as from our experience it nearly always does) the results can be transformative.
There is a degree of trial and error involved and the nature of the experience means it’s not possible to plan every detail and mitigate for every circumstance in advance. That is what gives a participatory event its energy and is at the core of much of its power, but it can also make running them more of a white-knuckle ride than more traditional events where every session is scripted and uses PowerPoint.
Though it could well be argued that this is what also makes them as stimulating and engaging to facilitate as they should be to participate in.
