This document discusses social innovation and co-creation. [1] It defines co-creation as the systematic process of creating new solutions with people, not for them, which involves a broader scope of people, new sources of knowledge, and design-driven processes. [2] The challenges of enhancing government's capacity for partnership with social innovators are also examined. [3] Questions are raised about which collaborative approaches to innovation work best under different circumstances and for different actors like government and social innovators.
