The document discusses how many reform initiatives in developing countries fail due to a tendency known as 'isomorphic mimicry,' where governments superficially adopt reforms without achieving real improvements. It introduces the 'problem-driven iterative adaptation' (PDIA) approach, which emphasizes solving locally-defined problems, fostering experimentation, and involving diverse agents for sustainable change. The authors argue that genuine improvements in state capability rely on focusing on functionality rather than mere compliance with external standards.
