The Galbraith article gives us the opportunity to think out loud about the purposes and practices of field activity, and in responding, this article argues that Galbraith is more concerned with the technical application of a method rather than investigating knowledge production. Using Bourdieu's theory of practice enables critical evaluation to be a social practice and the author positions herself as a knowledge worker concerned to describe and understand the interplay between agency and structure. Chaos theory enabled the author from the mid-1990s to problematise systems theory as the preferred way of generating leadership and management prescriptions for educational professionals. This remains relevant today and it is argued that Galbraith's continued reliance on improving systems theory means that the opportunity is lost to examine the exercise of power within and surrounding complex organisations.
