There is a scarcity of research regarding the process of introducing market orientation into the not-for-profit sector. Understanding this process would greatly assist the not-for-profit sector, which is under increasing pressure to obtain funds to operate and offer appropriate services. In this article, we examine the successful introduction of market orientation into three Australian charities and identify the stages of implementation. The introduction of market orientation is analyzed from a discourse transformation perspective and a praxis framework is developed. This is amongst the first studies examining the transition to a market orientation discourse within charity organizations and the first study to develop a praxis framework to guide managers. The study also pioneers a discourse transformation perspective in market orientation research. The article thus extends our knowledge of market orientation within the not-for-profit sector and increases understanding of practitioner engagement in marketing activities.
