The study discusses the three roles of normative assumption in the theory and practice of innovation management: (1) they define the value of innovation, (2) specify its luck, and (3) determine some goals and methodologies of managing the luck of innovations. The crucial questions of the investigation are as follows: What does 'luck' mean in theories of innovation management?, and What is luck in the practice of innovation management? The conceptual analyses present logical links which occur between the normative premises of some canonical theories of metaethics and definitions of luck. In the context of these analyses the study discusses some prerequisites for responsible decisions relating to innovations. The paper illustrates some ways of using philosophical methods in the theory of innovation management.
