Welcome to the 19th KM4DEV Knowlege Café on Liberating structures. For the KM4Dev community, liberating structures represent patterns of group interaction that liberate our collaborations. They can power up knowledge management at many levels. LS are simple, potent group processes that really bring EVERYONE to the center of collaboration (and facilitation). They make each and everyone of us an active citizen of our collective learning and destiny. This Knowledge Café will unpack LS through firsthand experience, exploring how they can support KM work in concrete and deep ways. We will finish by examining what each of us could do about and with them.
