Nowadays, innovation is a major stake for development and durability of many companies and institution’s activities. In our work, we are interested in interpersonal communication problem in innovation context. We focus on the upstream of innovation process and we consider the means that can be used. First to leverage organisation’s innovation perspective and second to solve innovation problem proposed by a strategic decision maker. To do this, we believe that people charge with solving an innovation problem should manage some difficulties: to identify what can be an innovation for the decision maker, to define the objects with a big innovation potential, communicate to his possible partners the innovation field to investigate and to find ideas to innovate etc. Then, we try to identify and to present these ideas to contribute to decision making process. At this time when the Web is really the universal source with access to formidable information quantities, we use it to establish some creativity and idea sources for innovation. This paper presents a method to solve these communication problems. It presents a tool box which potentialities are illustrated by an example of the management of a “new chair” development problem.
