It was actually a discussion between the OAG and the ANAO. The OAG had two specific areas that they wanted the peer review team to examine and they largely suggested what the objective and the scope would be. We then discussed that. In fact, some of the details were subject to negotiation, such as the timeframe. That was subject to negotiation between the two offices and also in involving other peer review teams.
