Summary

A strategy for building a mission-led government, published on April 27, 2026, outlines three essential actions to overcome current digital infrastructure challenges characterized by fragmentation and inflexibility. The first action advocates reclaiming sovereignty over core information infrastructure from third-party vendors, which often retain data and intellectual property, leading to silos and duplicated efforts. The second proposes enabling "composable government" by adopting a microservices-inspired approach to create reusable digital capabilities across departments like DWP, DHSC, DBIS, DfE, and DSIT, enhancing efficiency and agility. Finally, the strategy suggests using AI for policy implementation, envisioning AI engines, such as Thoughtworks' AI/works™ Agentic Development Platform, to automate software development, encode policy paths, and enable rapid adaptation to policy shifts and "what-if" analyses, ultimately bringing joined-up government within reach.

Key takeaway

For government leaders aiming to transform policy into citizen outcomes, your focus must shift to digital sovereignty and composability. Reclaim control of core digital infrastructure from external vendors to eliminate silos and duplication. Implement reusable digital capabilities across departments to enhance agility. Furthermore, explore AI platforms, like AI/works™, to automate policy implementation and enable rapid adaptation to changes, ensuring your initiatives deliver lasting, joined-up government services.
