Since the turn of the millennium, human resource transformation (HRT) has emerged as a popular management concept among organizations and consultants around the world. HRT has been presented as a recipe for how to transform the traditional personnel function and make personnel and HR work in more business-oriented, cost-effective, and value-creating ways. Through a comparative study of the actors that make up the so-called “management fashion arena” around HRT in the Scandinavian countries (Norway, Sweden, and Denmark), the study provides insight into how the national actors influence and shape the diffusion of popular management concepts. The study shows that there are both similarities and differences between how the supply side is configured in the three countries. For example, large consulting firms have played an influential role in all three countries, while the influence of actors such as business schools and professional organizations varies considerably between the countries. The findings also suggest that there are powerful alliances between actors involved in the diffusion of HRT. Overall, the study sheds light on the global diffusion and “travel” of a predominantly North American-based HR concept and its reception in Scandinavia.
