inventory and warehousing systems were used
in 47 factories (63.5%). The results indicated a
fair adoption rate for such systems. Part of the
reason for that is the influence of partnership with
global firms and international organizations that
outsource part of their production within Al-Hasan
Industrial Zone. It also seems that accounting and
human resources systems were more popular as
it is a major function for any firm regardless of
their size of operations. This conclusion might
be as a result of another test we did on the size

of firms with respect to their sales and number
of employees.
Using supply chain management systems
(SCMS) was not that popular as only 8 firms used
an extended system (11%), and the reason for
that are the distinctiveness of the sample, as the
sample in the first study came from an industrial
zone, where international contracts are more com-
mon and a closed system from the local market is
forced in this free zone. Such situation might be
in a lesser need to an extended integrated system
