With allies such as the CCAF and the AFRC, the Office linked audit expertise with the political problem of eradicating government deficit and debt, and of managing government in a more “businesslike” manner.

Sites of ambiguity in an organization become pockets of receptivity for the intervention of areas of expertise that allow professional groups to expand their jurisdiction (Llewellyn, 1998).
