We welcome CDDO’s efforts to establish strong cross-government co-operation and collaboration to identifying and addressing legacy IT issues. Since our December 2021 report on the Challenges in implementing digital change, CDDO has worked with all departments to establish a common methodology across departments for prioritising legacy risk. It has developed a framework to identify vulnerable legacy systems and tested it with six departments including Defra. Covering 105 digital systems across the six departments, this has highlighted those which need immediate work. CDDO intends to use the framework with the remaining departments by the end of 2023. CDDO has worked closely with departments in the development of its Roadmap to identify problem areas that need to be tackled and has introduced a set of commitments that all departments have signed up to and agreed to fund from within their own budget. CDDO is also working with departments to determine how significant the financial benefits from addressing legacy can be, and it expects this will support departments’ bids for funding to HM Treasury. 8 Tackling Defra’s ageing digital services Recommendation 7: As part of the Treasury Minute response, CDDO should set out whether it is getting the traction needed from departments to achieve its missions, and report annually thereafter on its progress and any difficulties in working with departments.
