can recognize that what we called importance is just as extensive a property as many
others, as software functional size is expected to be, too.
When estimating the software functional size (number of Cfsu), the only
criterion is the size itself. Consequently, we can consider a simple AHP hierarchy,
with only one level (and the objective estimated size above it); the nodes of this
level are the n items listed by the estimator, eventually prior to the functional
decomposition (this list could even include everything from possible functional
processes to macro-processes).
In order to review the possible ways to merge E&QCFFP and AHP, let’s ...
