Departmental delivery commentary

Compared to financial year 24/25 Q4, the NISTA/SRO Delivery Confidence Assessment (DCA) rating at 25/26 Q4 increased to Amber. This is primarily due to the following factors. 1. Delivery continues and tangible progress is being made across multiple project lines. 2. Approval to maintain Heavy Forces communications via BCIP 5.7 remains affordable, and is awaiting Treasury approval. 3. The programme ambition to reset its delivery approach through a Strategic Outline Case has yet to be approved. 4. The programme is therefore operating at risk, pending Strategic Outline Case and wider Defence Investment Plan decisions.
