In a context where cities are asked to do more with less, learning from others offers a way to accelerate action without starting from scratch. Across contexts, sectors and governance systems, learning from the successes of others has become a frequent feature of local policymaking. Yet, these practices remain largely informal and unevenly structured. The gap is therefore not one of awareness, but of translation: how to move from exposure to external ideas to their effective, context-sensitive implementation. This toolkit helps cities approach idea adoption not as an opportunistic or occasional activity, but as a strategic, continuous and collaborative practice, embedded in the way they design and deliver public policy.
Adopting an idea from elsewhere is not a discrete decision, but a process that unfolds over time, requiring institutional work at each stage. It begins with the capacity to engage with external ideas in a deliberate way, shaped by leadership, organisational culture, internal co-ordination and access to networks. It continues with the ability to assess whether an idea can work locally, moving beyond compelling narratives to examine causal mechanisms, contextual conditions, and feasibility. It culminates in adaptation and implementation, where ideas are reinterpreted, negotiated, tested and embedded within local governance arrangements. Across all stages, the process is iterative rather than linear, and shaped by political, administrative, and financial constraints.
Ideas do not travel intact. What cities adopt are not ready-made solutions, but configurations of principles, practices and institutional arrangements that must be reassembled within a new context. At the same time, engaging with ideas as coherent programmes can support more structured adaptation by helping cities identify and preserve the core logic that enabled success in the originator city. Successful adoption in this sense depends on a combination of factors that cities can actively shape: aligning external ideas with local priorities, empowering staff to explore and experiment, engaging with networks strategically, grounding decisions in evidence while recognising contextual differences, and sustaining political and financial support throughout implementation.
A move from ad hoc engagement with external ideas to more structured approaches to idea adoption strengthens local governments’ capacity to design and implement effective policies. As cities face increasingly complex and shared challenges under constrained resources, the ability to systematically identify, assess, and adapt ideas from elsewhere becomes a critical capability. Strengthening this capability does not necessarily require new institutions or significant additional resources, but rather a more deliberate use of existing ones: embedding learning in routine practices, documenting experiences, and creating feedback loops between exploration, assessment, adaptation, and implementation.
