Tables 7, 8, 9, and 10 show pairwise priority assignments for the alternatives based
on Contribution, Passenger Importance, System Owner Importance, and Developer
Importance criteria, respectively. The assigned values are subjective and based on the
authors' experience.
Now, we need to establish the relative importance of each stakeholder (level 3 of
the tree) as well as the relative importance between the two criteria (level 2 of the
tree). Tables 11 and 12 show the relative importance (preferences) of each criteria for
both levels of the tree, again attributed by experience.
It should be noted that for large problems the total number of required comparisons
is quite time consuming. Nevertheless, there are ways to avoid deriving priorities for
