The target was set because we wanted to make sure that people were using the instruments that we were establishing. This is based on volume and practice. We've given ourselves a bit of a stretch goal. At 15%, it may not seem to be significant to have all of that done through the supply arrangements and the standing offers, but we thought that was a fairly significant stretch for us to achieve, because these are pre-competed instruments that allow and simplify the processes government departments and agencies use.
Not all of these are mandatory. That's one of the reasons we set this target. In terms of the proportion of total contracted value awarded competitively, this is a goal that we set because we are of the view that having a competitive process gets best value for the government. These are the targets we have set, recognizing that in some instances, competing is not necessary because the suppliers are unique, because of the time constraints, or because of national security requirements.
