Around 90 selected people met in the centre of Bari to shape the future of La Scuola Open Source, an Educational Institute, Centre for Research and Consultancy — in Art and Technology — for Industry, Trade and Handicraft (digital or not) born in 2016. SOS organised this 12 days co-design workshop to map, analyse and imagine the system of the school through 3 axes: X - identity, Y - tools and Z - processes. I joined the Z group wich was divided into three branches: community, debug and governance. In my debugging team, we investigate the school-system, flows of information and stakeholders to find bugs and propose solutions. We realized an editable vademecum in which we explained tools, ways of thinking and results of the debugging process. All outputs are open and ready to be used by other institution and independent cultural centre.
