Distinguishing between concept and knowledge
Knowing innovation practitioners and stakeholders

According to the C/K theory, designers approach either the C domain of concepts, or the K domain of knowledge. On the one hand, proposals for new product ideas are formulated (at this stage, they are neither validated nor verified). On the other, new knowledge is created, and existing knowledge is used to assess the feasibility of ideas. Innovating therefore means "expanding" the space of new product concepts you have in mind, and "expanding" the space of knowledge you master to turn your ideas into reality. Innovating also means moving from the C to the K space, as creativity and concretization dictate.
