The Commonwealth departmental machinery of government is changed by using Orders in Council to create, abolish or change the name of departments. Since 1906 governments have utilised a particular form of Order in Council, the Administrative Arrangements Order (AAO), as the means to reallocate functions between departments for administration. After 1928 successive governments from Scullin to Fraser gradually streamlined and increasingly used the formal processes for the executive to change departmental arrangements and the practical role of Parliament, in the process of change, virtually disappeared. From 1929 to 1982, 105 separate departments were brought into being, as new departments or through merger, and 91 were abolished, following the merger of their functions in one way or another with other departments. These figures exclude 6 situations where the change was simply that of name alone. Several hundred less substantial transfers of responsibilities were also made between departments. This dissertation describes, documents and analyses all these changes. The above changes can be distilled down to 79 events termed primary decisions. Measures of the magnitude of change arising from the decisions are developed with 157.25 units of change identified as occurring during the period, most being in the Whitlam and Fraser periods. The reasons for the changes were assessed and classified as occurring for reasons of policy, administrative logic or cabinet comfort. 47.2% of the units of change were attributed to policy, 34.9% to administrative logic, 17% to cabinet comfort. Further conclusions are drawn from more detailed analysis of the change and the reasons for the changes.

Is scenario planning a process that can be used by agencies of the Australian Public Service to generate and develop information that is relevant to the future, and thereby make possible improved strategic planning? This is the core question of this dissertation. The first part of the thesis is devoted to the case for investigating the benefits of scenario planning. Literature defining and describing the benefits of scenario planning for both private and public sector organisations is examined, and factors that appear to be critical to effective implementation of the process are discussed. Against this theoretical background the empirical evidence of seven cases of the application of scenario planning in six agencies of the Australian Public Service is considered. Several conclusions are drawn on the basis of the data obtained from the seven cases studied. Scenario planning is more likely to make possible improved strategic planning of public sector agencies such as those that comprise the Australian Public Service (irrespective of their function or size) if it has the active involvement of senior management during the developmental phase of the process, and their ongoing support for any follow-up activity. In addition, a well resourced and in-depth research phase is integral to the success of the process. Even if these elements are not present to a high degree, a well managed scenario planning exercise will improve to some degree the ability of an agency�s senior executive to think more openly and proactively about its future business context. In addition, well resourced and properly supported scenario planning can also help a public sector agency to improve the quality of its information gathering, test the viability of its strategy options and develop appropriate contingency plans.

In 1996 the Howard Government came to power in Australia. At that point in time the commonwealth budget was in significant deficit, the economy was weak and there was significant commonwealth debt. To address these issues the Howard Government moved to implement several cost savings and income generating projects began under the outgoing ALP government. In addition, part of the Howard reforms was the move toward the private side in the public / private mix in the delivery of government services. One of the high profile and significant projects was the outsourcing of the commonwealth public sector Information and Communications Technology (ICT) delivery. It was called the IT Initiative and was managed by the Minister for Finance, the Honourable Mr Fahey. Mr Fahey had earlier attempted significant outsourcing projects whilst in NSW government; at one time Mr Fahey was NSW Premier. The intent of the IT Initiative as policy was to achieve better and more cost effective ICT services for the commonwealth. This research reviews the efficacy of the IT Initiative. Under the Westminster system, governments can implement government policy as approved by the parliament. However not all policy is reviewed by the parliament. In this case the IT Initiative was part of the Howard pre-election policy and therefore was considered 'mandated' by the electorate. Irrespective of this approval, was the IT Initiative supported by the research at the time and did the IT Initiative and its implementation make sound business sense when compared to the research and models and in particular effectiveness, efficiency and economy. This thesis will review the IT Initiative using both static and dynamic models using Transaction Based Economics (TCE). Both models will support the view that the IT Initiative as practiced was a relatively high risk strategy. The thesis will utilise TCE and risk management to develop a risk profiling model for ICT with effectiveness, efficiency, economy as the three dimensions. Finally, the risk-profiling model, while based on earlier modelling, provides a new insight into the issue of centralising versus decentralising of government operations especially as these approaches relate to novel technological applications across various departments.
