When performing an audit of a client relationship management (CRM) system migration project,
which of the following should be of GREATEST concern to an IS auditor?

A.
The technical migration is planned for a Friday preceding a long weekend, and the time window
is too short for completing all tasks.

B.
Employees pilot-testing the system are concerned that the data representation in the new
system is completely different from the old system.

C.
A single implementation is planned, immediately decommissioning the legacy system.

D.
Five weeks prior to the target date, there are still numerous defects in the printing functionality
of the new system’s software.

Explanation:

Major system migrations should include a phase of parallel operation or a phased cut-over to
reduce implementation risks. Decommissioning or disposing of the old hardware would complicate
any fallback strategy, should the new system not operate correctly. A weekend can be used as a
time buffer so that the new system will have a better chance of being up and running after the
weekend. A different data representation does not mean different data presentation at the front
end. Even when this is thecase, this issue can be solved by adequate training and user support.
The printing functionality is commonly one of the last functions to be tested in a new system
because it is usually the last step performed in any business event. Thus, meaningful testing and
the respective error fixing are only possible after all other parts of the software have been
successfully tested.
