The evaluation of national government involvement is itself
complicated by the long-term development process accompanying
these large-scale projects – which often include significant changes
in the project plans – as well as by the complexity concerning the
criteria involved. On the one hand, this complexity is due to the
necessity to convert theoretical criteria concerning the contribution
of projects to national wealth into more practical criteria that
can be monitored and evaluated, such as urban quality or employment
growth. On the other hand, this complexity results from the
need to use qualitative indicators. This again highlights how
important it is for the national government to put more effort into
specifying the objectives of their involvement in local projects. It
also demonstrates how important it is to have a clear evaluation
framework for these projects, in which criteria are related to the
specific aims of the national government in unambiguous terms.
