This article proposes a propulsion model characterizing 7 different types of creative contributions in any domain. Four of these types of creativity accept current paradigms of work; 3 of the types reject these current paradigms. The basic notion is that creative contributions differ not only in the amounts of creativity they display but also in the types of creativity they display. The article discusses (a) creative contributions and why there is a need for a taxonomy of them, (b) some existing models of creative contributions, (c) a propulsion model for understanding creative contributions and 7 types of contributions that follow from the propulsion model, (d) why such a model can be useful in evaluating creative work, and (e) some phenomena that have been observed in the field of creativity and how they can be explained in terms of the model.
