Conclusion (the committee's words)
In taking forward the Programme, NS&I launched multiple procurements and planned to deliver four transitions in parallel, with no understanding of the risks that this was exposing the organisation and its customers to. NS&I said it had identified supply chain risk as a key area of focus.38 However, NS&I focused more on how it had handled past issues, telling the Committee how it had developed contingency plans when Atos had financial difficulties in 2023; it did not provide evidence that it had considered how to manage the current contracts.39 When asked if it was confident that it had resolved the issues with procurements, NS&I could only say that it had awarded contracts. NS&I acknowledged that these still contain the original milestone dates, which would need to be changed to take account of delays in NS&I’s Programme implementation.40
