This paper is focused on the concept of visualization as a potential tool to foster knowledge translation. We investigate how using ad-hoc visual tools supports knowledge translation and knowledge transfer. The empirical case under analysis concerns the setup of a multi criteria decision-making model to analyse and select alternatives related to the factors that upgrade the lean production process quality, at a FCA Plant. Knowledge visualization can be interpreted as the interactional process where different players translate their know-how, share a framework and develop common ground to support decision-making.
