The Shared Services process has been such that after industry consultation and an invitation to qualify, those that were shortlisted are currently going through—as we understand it—a “review and refine requirements” phase. They've shortlisted down to successful proponents. Past that, when they down-select to as few as three, they'll issue the final RFP. Having been locked out of the process, both of us at earlier phases in this procurement were not aware of what the final arrangements will look like and have no visibility to it.
