An organization has contracted with a vendor for a turnkey
solution for their electronic toll collection system (ETCS).
The vendor has provided its proprietary application software
as part of the solution. The contract should require that:
A. a backup server be available to run ETCS operations with
up-to-date data.
B. a backup server be loaded with all the relevant software
and data.
C. the systems staff of the organization be trained to
handle any event.
D. source code of the ETCS application be placed in escrow.
Answer / guest
Answer: D
Whenever proprietary application software is purchased, the
contract should provide for a source code agreement. This
will ensure that the purchasing company will have the
opportunity to modify the software should the vendor cease
to be in business. Having a backup server with current data
and staff training is critical but not as critical as
ensuring the availability of the source code.
