Which of the following should be in place to protect the
purchaser of an application package in the event that the
vendor ceases to trade?
A. Source code held in escrow.
B. Object code held by a trusted third party.
C. Contractual obligation for software maintenance.
D. Adequate training for internal programming staff.
Answer / guest
Answer: A
Contractual obligations may not be enforceable if the vendor
ceases to trade. Training is irrelevant, as programmers
cannot maintain an application unless source code is
available. Thus, having object code available also is not an
adequate solution. Only ensuring that the source code can be
obtained in the event that the vendor cannot provide support
will protect the purchaser.
