It is up to five years to fix Phoenix, so more funding will be required.
Additionally, if the government is going to be looking at a new system that goes peripherally to Phoenix—and the new system can't be in place until Phoenix is fixed—the government is going to have to hire more staff to work on that new system to advise, to let them know if it's working or not and to do the testing.
In terms of a public inquiry, what we're asking for in a public inquiry is why no senior bureaucrat said “no”. It's not so much who caused Phoenix within the bureaucracy, or who were the players. We know who those players were. We were talking with the government from 2011, and we're still talking to the government. At no time did any of those senior bureaucrats say, “no”.
In our first meetings in 2011, we asked for the business case for this new system that was being put in place, and we were refused. I received the business case about a year ago. Had we received that business case at that time and were able to talk about it publicly, it would have been very clear that the kind of robust analysis that was necessary to have a pay system that actually paid people was not being considered.
