Four basic dimensions of organisational structure are distinguished: the degree of formalisation or bureaucratisation, the degree of differentiation or specialisation, hierarchy and the extent of centralisation. The article will show that variations in the organisational structure of the APS are attributable to a range of factors including the political context, size, task complexity, the grading system, considerations of efficiency and political factors. The relative importance of these factors varies according to which aspect of structure is examined. Mechanistic organisational structures predominate in the APS due to the nature of the tasks performed, the imperatives of political control and the requirements of staff classification. - Reproduced  aPublic administration  aBureaucracy  aAdministrative reorganisation  aCivil service  aAustralian Journal of Public Administration
