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 betested 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.
