This document discusses modernizing public administrations through concepts like New Public Management, whole-of-government approaches, and now through delegation, outsourcing, and evaluating public policies. It notes that administrations are not just bureaucratic but also opportunities for innovation through co-creation processes. The document describes a program called "Territoires en residences" that places interdisciplinary resident teams within public buildings for 3-6 months to prototype innovations through approaches like participatory action research and ethnography. The goal is to reframe policies through experimentation within an administration.
