Ansell and Gash’s (2008) definition of collaborative governance remains widely accepted. Over a decade on there has been much innovation in the field, increasingly incorporating both digital and face-to-face spaces. Hybrid processes are created between invited and invented spaces (Cornwall 2009), which aim to move beyond formal forums, towards a more organic dialogue that happens simultaneously online and offline. This chapter attempts to update Ansell and Gash’s definition in light of these innovations and borrows from the existing literature to build a framework of collaborative governance. We use this framework to analyse three UK-based cases: NHS Citizen, a deliberative system within the NHS; co-production of knowledge between residents and institutions in South Reading; and Participatory City, a new model of coproduction of outcomes based on micro-participation. These new spaces of collaboration inevitably engender conflicts and complex accountability dynamics, as they challenge traditional forms of collaboration between institutions and citizens.
