The objective of this audit was to provide a strategic review on the progress of the Tax Office's implementation of the Change Program.
 
To achieve this, the ANAO examined:

• the planning for, and governance of, the Change Program, particularly in relation to the management of risk and the assurance framework established by the Tax Office, and its management of contractual arrangements for the project;
• implementation issues associated with Releases 1 and 2 of the Change Program, and more specifically in relation to Release 3, the first use of the new ICP system to process FBT returns; and
• the funding of the Change Program, including measurement and attribution of the costs of the project and consideration of any benefits realisation to date.

The objectives of the audit were to determine whether FaCS and Centrelink had: a valid Business Case for the Edge project, as revised from time to time, including estimated costs, actual costs, and expected benefits; effective governance of the project, including reviews at critical points in the project and subsequent decisions to continue or, in the final analysis, to discontinue; an appropriate contract with SoftLaw, which was adequately managed; delivered appropriate advice on progress, project viability, and acceptable solutions to technical issues to Executive of FaCS and Centrelink during the project; and valid reasons for discontinuing the project. The ANAO began this audit in March 2004, four months after the Edge project was terminated, following the Auditor-General's agreement to a suggestion by the Joint Committee of Public Accounts and Audit that the project was a suitable subject for audit.
