This paper investigates the influence that undertaking a professional doctorate has on the practice of the graduate and their workplace or organisation. There is a growing literature on how undertaking such advanced development influences the individual graduate at the personal and professional level but there is little evidence of a wider impact on practice in general or at the organisational level. This study seeks to address this issue through a qualitative study of practitioners from a range of professional arenas and sectors who have graduated from a professional doctorate within the past 10 years. Through thematic analysis of semi-structured interviews and the candidates' project reports, we explore their experience of applying their learning within their workplaces providing insight into the level and degree of influence such development can have on organisational contexts. The paper does not focus on the academic or personal impact of their experience as the intention of these particular doctoral researchers is the creation of new knowledge embedded in practice.
