E-Government Maturity Model

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.
