This concept paper introduces the Governance Synchronization Gap framework as a new perspective on institutional transformation. Building on the Architectural Anti-Corruption Approach, the paper argues that reforms often remain incomplete because interconnected institutions evolve at different speeds, creating Governance Synchronization Gaps, Reform Adaptation Windows, and opportunities for governance vulnerabilities and corruption. The framework introduces four interconnected concepts: Governance Synchronization Gaps, Reform Adaptation Windows, Ring Logic, and Closed Reform Cycles. The central argument is that sustainable transformation depends not only on what governments reform, but also on whether interconnected institutions transform in a synchronized manner. The paper proposes synchronization as a missing dimension of governance transformation and outlines a future research agenda toward a Theory of Institutional Synchronization. The framework contributes to research on governance architecture, anti-corruption, public administration reform, digital government, population registers, institutional resilience, and sustainable governance transformation.
