概要	Digital government assessment measures how far a public administration has moved beyond merely digitising existing processes toward becoming digital by design — using data, platforms and user-centred service design as core operating principles. The OECD Digital Government Index, built on its six-dimension Digital Government Policy Framework, is the leading instrument, scoring countries on dimensions such as being digital by design, data-driven, government as a platform, open by default, user-driven and proactive. Evidence is collected through a structured survey, verified, scored and aggregated into a weighted composite. It complements the supply-focused UN E-Government Development Index.	An e-government maturity model is a staged framework that describes how public administrations evolve their digital service delivery from simple online information toward fully integrated, transaction-capable government. The most influential formulation, proposed by Karen Layne and Jungwoo Lee in 2001, sets out four stages — cataloguing, transaction, vertical integration and horizontal integration — through which agencies are expected to progress. Maturity models translate a diffuse modernisation agenda into an ordered ladder of capabilities that can be assessed, compared and benchmarked across agencies and countries. They underpin international instruments such as the UN E-Government Survey and its Online Service Index.
