The article compares the ways in which different public sector organizations respond to similar federal government demands for public sector reform. The empirical basis of the article is a comparison of public sector reform in three agencies managing road systems in three Australian states. There are two constants in the research; namely, the nature of the responsibilities of the agencies with respect to the road network, and the demands of federal government policy for road reform throughout Australia. Yet within the ambit of these two constants, there is a distinctive contrast in the way the agencies have approached and implemented both policy and reforms. The article uses Hood's framework for viable organizational design options for variables relating to grid and group as an explanatory model for the results obtained from the research. Furthermore, it examines the utility of Hood's four styles of public sector organizations in order to explain different change outcomes in the three agencies studied.
