As I said to the member in my initial response, we are currently reviewing our technology base. In that review, open-source solutions will be considered alongside proprietary ones, and information and communications technology procurement and contracts will continue to be awarded on a best-value basis. All options are being considered, and the next technology upgrade could be an open-source solution, a proprietary solution or a mixture of both. In coming to final decisions, a range of considerations will be taken into account, primarily on a best-value basis.
