Functional analysis techniques do not answer quantitative questions, like ‘how
quick’ or ‘how cheap’. These are typically questions addressed by the quantitative
analysis techniques. Usually, architectural models do not provide sufficient information
to perform detailed quantitative studies. In our view, an approach for
quantitative analysis of enterprise architectures should make it possible to structure
and relate quantitative results obtained with existing detailed analysis methods
(e.g., queuing analysis or simulation).
