Since 2000, IBM and the Economist Intelligence Unit (EIU)
have worked together to build an e-readiness rankings
model of the world's largest economies. It evaluates the
technological, economic, political and social assets and
their impact on their respective information economies.
E-readiness continues to improve around the world in 2007,
but achieving it is becoming more complex. To reflect this,
the Economist Intelligence Unit has "raised the bar"
of e-readiness by modifying its ranking methodology. This
change in methodology, along with underlying improvements
in individual countries, has led to changes in the league
table.
