To respond to the member's question, it will be Shared Services that is responsible for the provisioning of that infrastructure and working with the vendor community and departments to make sure that we provide solutions in line with the needs of those departments.
As I said, we started with those that were the most complex and represented almost 50% of the total call volume. We're very confident, given that we've tackled the most complex, and almost half of the total government's call volume, that we can now scale at speed, having learned these important lessons, the remainder of the departments. We're working with them to make sure they don't get a system that is bigger and more complex than they need, or more expensive because it has security they don't need.
We'll be able now, having done the most complicated, to tailor solutions and move quickly to all of the remaining centres. We're working with them to get an inventory of their requirements and will layer on top of that the systems they have, contracts and end-of-life technology. By the fall, we'll have a plan for all of the remaining call centres.
