Sources of technological innovation: Radical and incremental innovation problem-driven to support competitive advantage of firms

A fundamental problem in the field of management of technology is how firms develop radical and incremental innovations that sustain the competitive advantage in markets. Current frameworks provide some explanations but the general sources of major and minor technological breakthroughs are hardly known. The study here confronts this problem by developing a conceptual framework of problem-driven innovation. The inductive study of the pharmaceutical industry (focusing on groundbreaking drugs for lung cancer treatment) seems to show that the coevolution of consequential problems and their solutions induce the emergence and development of radical innovations. In fact, firms have a strong incentive to find innovative solutions to unsolved problems in order to achieve the prospect of a (temporary) profit monopoly and competitive advantage in markets characterised by technological dynamisms. The theoretical framework of this study can be generalised to explain one of the sources of innovation that supports technological and industrial change in a Schumpeterian world of innovation-based competition.
