Functionality development of product innovation: An empirical analysis of the technological trajectories of smartphone

The purpose of this study is to analyze the driving technical characteristics in product innovation to predict technological trajectories. The analysis is based on hedonic price method and other approaches using empirical data of smartphone technology (N=738 models over 2008-2018). Results show technological trajectories supporting the evolution of smartphone technology. In particular, critical characteristics of technological evolution in smartphone technology are: RAM in Gb, 1st and 2nd camera in Mpx, memory in Gb and resolution in total pixels. Implications of innovation product management are discussed.
