A system contains many processes. Three common processes
that are “grouped” together are
transaction corrections,
adjustments, and cancellations
. These three elements work to
properly serve customers. Imagine a system that allows you to
register for a class online. The online system must give you a
way to correct any errors you made, such as registering for
the wrong class. This would be a
transaction correction
. The
system should also allow you to make adjustments, such as
adding or dropping classes. Finally, the system should allow
you to make
cancellations
, such as cancelling the registration
process entirely. Notice that all three of these
processes,
correction, adjustment, and cancellation
, work
together to provide you with one service, which is registering
for classes.
What type of requirements are
transaction corrections,
adjustments, and cancellations
? Select one.
