During the front end of innovation, teams embody abstract meanings into product concepts. The literature on Innovation of Meaning suggests that focusing on a single product-user interaction supports this process. This Moment of Meaning facilitates the development of shared meaning and knowledge. We explore how the Moment of Meaning acts as a Boundary Object to support the innovation process.We study six Innovation of Meaning projects in different companies to explore how the Moment of Meaning supports the transition from abstract meaning to a concrete solution. Attending company meetings and workshops, we collected extensive qualitative data on the usage of the Moment of Meaning.We identify four uses of the Moment of Meaning. Depending on its degree of abstraction and perspective, it represents a Metaphor, a Product Vision, a Core Feature or an Experience Concept. Our study sheds light on the reification of meanings in early stages of innovation. Also, we highlight the potential evolution of Boundary Objects over time. To managers, we provide actionable knowledge on how a simple boundary object could ease the transition from an innovation strategy to a concrete product concept.
