Description
We are seeking suppliers with the capability to deliver system integration services that enable seamless connectivity, data flow, and interoperability across a diverse and evolving IT estate.

While we follow a no or minimal customisation policy, we require suppliers with specialist skills in the development, upgrade, and integration of these systems to ensure maximum value is realised. Delivery is typically aligned to Agile methodologies, though other approaches may be applied depending on the project, programme, or portfolio context.
