Following an initial selection through a process of inviting expressions of interest, OGIT issued a restricted Request for Proposal for Human Resource Management Systems and Financial Management Information Systems. OGIT sought the services of the ANAO to provide an opinion on the probity of the methodology and procedures applied in the process of evaluation of tenders for acceptance to the Shared Systems Suite. The ANAO also agreed to review the formal procedures developed by OGIT and to test their operation to enable the ANAO to form an opinion, with a reasonable degree of assurance, on whether the evaluation process accords with the Commonwealth Purchasing Guidelines for open and effective competition and consideration for the development of Australian and New Zealand industry.
