problem with the MoneyNet system addressed by NTS was the
software's inability to take into consideration the multibanking
environment of Norwest. In this regard, the software did not fully
recognize all of the accounting relationships among the different
Norwest banks, and thus the accounting records were often incorrect
following a wire transfer.
NTS allocated five or six technicians to remedy the problem.
The technicians mapped out the appropriate accounting entries in
order to determine which entries were not properly made following
a wire transfer. They then filled in the gaps in the code.
Following each change to the code, the changed code was tested and
retested. The distributed wire project improved efficiency through
the elimination of much of the paper process. It also improved
reliability through the fault-tolerant system.
During the years in issue, the vendor released upgrades of the
MoneyNet software. The installation of these new releases posed
compatibility problems for Norwest as a result of prior changes to
the code made by NTS. The retrofitting process required a
comparison of the new and old vendor codes with the NTS
modifications to ensure that the required functionality was
maintained.
For all of the MoneyNet projects, NTS employed the SDM
process, continually testing the modifications to the system to
