Investing for Impact. Lessons with the Norwegian State Project Model and the first ivvestment projects that have been subjected to external quality assurance

The report provides a description of the Norwegian State Project Model, also
referred to as the government’s scheme for external quality assurance of major public
investment projects (the QA scheme). The scheme was introduced year 2000 (QA1) and
extended in 2005 (QA1). The first experiences can now be presented, mostly in the area
of cost estimation and cost management (QA2). The results show that 80% of projects
now remain within or on the Parliament approved cost frame. This is a very good result
compared with what might be expected earlier. Evidence indicates that the QA2 scheme
and the methodology used for cost estimation have had a positive effect. Some preliminary
experience with quality assurance of the choice of concept (QA1) is also presented in the
report.
