Paper aims: To define a model that describes the relationship among the main factors influencing knowledge transfer (KT) between new product development (NPD) teams. Originality: We offer a systemic vision of the relationship between the KT factors. All main KT factors are analyzed together considering the interdependence among them. Research method: KT factors from the literature were used for the model development, which was accomplished through a quantitative evaluation of scholars and practitioners. To test the model, a practical assessment was conducted in five firms using regression analysis. Main findings: The model describes the relationships of 15 main factors and it can be used for practical assessments or for future theoretical studies. Implications for theory and practice: The model can help practitioners to use knowledge of their teams for continuous innovation in NPD. It allows to perform diagnoses of the KT factors in the specific context of a given firm
