The document discusses the IDeA Efficiency Exchange, a tool being developed to help local councils in the UK address efficiency challenges through benchmarking, best practices, and peer collaboration. It describes activities for councils to identify challenges and successes, imagine solutions, and draft requirements for collaborative problem solving and knowledge sharing tools. These include online conferences, benchmarking data, and a repository of best practices to facilitate sharing lessons learned. The goal is a technology platform and network of councils that supports generating, learning, and applying efficiency practices.
