Abstract
This article proposes a conceptual model to analyse the role of quality orientation and collaborations in firms' management innovation, and also the impact of management innovation to product, process and marketing innovation. Moreover, the analysis considers organisational size as a key moderating factor in order to investigate whether the relationships among the model factors vary between small and medium size firms. To achieve these objectives an empirical survey was conducted among 429 firms. The structural relationships among the latent factors were determined through SEM. The findings show that the probability of success increases when firms use quality orientation and collaboration to support management innovation efforts. In addition, the findings suggest that management innovation positively affects product, process and marketing innovation while the organisational size acts as a moderator in the relationships among quality orientation, collaborations, management innovation, - product, process and marketing innovation, respectively.
