This paper discusses the possible applications of different types of experiment methods in innovation research. The paper argues that the experiment as a research method has been a largely missed opportunity in innovation research, in particular for creating applicable knowledge for businesses and organisations in the shape of new innovation tools and methods. The paper applies an analytically based limitation of the experiment method which includes an array of both quantitative and qualitative approaches. The use of experiments for such purposes is illustrated through a comparative study of four experiments concerning open innovation in service businesses and organisations. The case studies show how different experiment methods provide new opportunities for innovation research and how they can create new and applicable knowledge about open innovation. Thus the paper argues for applying experiments as an addition to other research methods in innovation research.
