The document explains the Public Policy Lab’s (PPL) “Layer Cake” approach, which identifies different layers within government systems where designers can intervene to improve service delivery.

The framework emphasizes the importance of working with all levels of stakeholders—public service users, frontline staff, service managers, and policymakers—to create holistic tools and services. It focuses on incorporating the voices of the public into decision-making, fostering collaboration across agencies, and designing services that prioritize the needs of historically marginalized populations.
