The document discusses stakeholder contribution to innovation. It discusses several key points: 1) All stakeholders are able to contribute ideas, information, or opinions that can directly or indirectly create value. 2) Innovation often depends on "unknown" information that may be discovered through appropriate networks of knowledge. 3) Participatory innovation spaces, such as living labs, allow effective participation of stakeholders in innovation processes through experimentation with users, studying users, and building communities of users.
