5. Conclusions and managerial implications
The importance of design as a significant contributor to NPD success has been emphasised by many authors (e.g., Verganti, 2009; D’Ippolito et al., 2014; Moultrie and Livesey, 2014). However, there is limited evidence over the effectiveness of different roles designers can play in NPD (Perks et al., 2005; Candi and Gemser, 2010), and the difficulties of integrating design into the NPD process have been emphasised repeatedly (Beverland, 2005; Micheli et al., 2012). The aim of this study was to combine the insights of previous qualitative studies on the roles played by design in NPD with a systematic quantitative analysis. The main contribution of this research is to our understanding of the impact of alternative roles of designers on NPD outcomes. More specifically, using detailed data from three waves of the Irish Innovation Panel, we are able to quantify the value of extending the role of design beyond that of functional specialism to having higher levels of engagement within the NPD process. In more conceptual terms, our analysis examines the relative value for NPD outcomes of utilising design in NPD, and the benefits of a continuous involvement of design in NPD.
