Radical innovation is becoming essential to insure firms stay competitive. Nevertheless, R&D departments struggle to achieve systematic innovation processes. The management of an innovation field requires adapted tools to the diversity, broadness and flexibility of the generation of innovative ideas. To face this challenge, we propose the use of a set of visual tools. These allow the abstraction of three fundamental innovation field dimensions: 1) the nonlinearity of the ideation process; 2) the degree of maturity of a technology and 3) the stakeholder diversity of an ecosystem. We propose an Innovation Map, a synthetic tool grouping several visual representations that allow describing these three dimensions of an innovation field. Having all aspects simultaneously described by a tool is enriching since it makes it possible for the visual representations to complement each other. This managerial tool was applied inside Renault, in the automobile sector, for the mapping of the electric vehicle charging, a strategic field in electric mobility. We tested the tool with several internal R&D stakeholders of the innovation field having different profiles and responsibilities. They perceived the Innovation Map as a useful tool to point out and share various strategic aspects of an innovation field, as well as establishing potential partnerships. This collaborative research is a first step towards the establishment of a visual language framework that managers can apply to communicate, organize and understand an innovation field.
