How about picking an ongoing massive challenge?
Hello and welcome to Edgeryders 
I was hoping someone would tackle this theme in one of the sessions and will definitely be attending this. The reason being that I believe it is key to our ability to tackle very messy problems like the ones I pointed out after the International Mayor’s conference on the “refugee crisis” (see writeup here).
My feeling is that one obstacle to engage with discussions about new ways of doing things is the sense that “aaarrgh I cannot cope, not another thing”. Perhaps going through the tools and methods with the explicit aim of identifying some small things they can do to make their everyday work reality better?
Right now one obvious context where people need help, but are already struggling to cope, is grassroots ngos and others where there is a lot of chaos and self organisation. I met a couple of people working in Vienna who expressed interest in getting better at documentation and institutional memory, because of high volunteer turnover and the need to constantly repeat the same information over and over again which is exhausting…
