in Section 2.4, an important aspect of
successfully using the benefits of information
technology is to properly aggregate the available

reduce and to aggregate the information to be
exchanged are described. Curran (1991) emphasizes
that EDI is only a tool; what is really crucial
for logistic chain integration is the next phase
after EDI, including the development of integrated
information systems using EDI techniques.
