There is much talk today about 'knowledge management' and 'intellectual cap
ital'. And, looking at enterprise modelling, one could say that an enterpri
se model is a visual way to capture knowledge about the enterprise. It can
be suggested that much of what is being done in enterprise modelling is not
achieving what enterprise leaders want to achieve, and that is to add sign
ificant value to the enterprise. This paper begins to address what is neede
d to add value by describing an enterprise modelling framework comprised of
36 different classes of enterprise models. Within this framework, there ar
e six classes that specifically address increasingly sophisticated concepts
of enterprise value. Examples of some of these classes, called valuemetric
enterprise models, are given from actual models. But this paper only begin
s to address this challenging area. It is hoped it will trigger further dis
cussion and development of valuemetric enterprise models.
