This article contributes to the knowledge in the field by proposing a typology of innovation management models, highlighting model's biases, gaps, strengths and weaknesses, and by identifying important tensions among models that spillover to the innovation management field in both research and practice. This article discusses conflicts regarding the limits of the innovation process (events that start and end the process and complementary approaches), the limits of focusing on processes, the differentiation of research and development and new product development activities. In the end, the article addresses emerging approaches related to radical innovation, design thinking and startups, and stresses contributions for research and practice.
