The purpose of the audit is to assess the operations of the Ministry of Finance in steering the centralized central government procurement function and to examine the quality of the knowledge base applied in the steering. The Ministry of Finance steers the purchases in central government for instance by the central government procurement strategy, by making decisions on joint procurements, by developing the purchasing methods, and by being responsible for the general procurement terms and conditions. Another purpose of the audit is to examine whether the agencies and institutions have complied with the joint procurement obligation to which they are subject. The law requires that an agency or institution shall organize its procurement function in such a manner that it applies the agreement competitively tendered by the central government joint procurement unit. In addition, the audit examines whether joint procurements have promoted the policy objectives set for public procurement. These goals are related to environmental friendliness and social responsibility.
