Certified Information Systems Auditor (CISA) — Question 1258

Which of the following should be of GREATEST concern to an IS auditor reviewing project documentation for a client relationship management (CRM) system migration project?

Answer options

• A. Five weeks prior to the target date, there are still numerous defects in the printing functionality.
• B. The technical migration is planned for a holiday weekend and end users may not be available.
• C. Employees are concerned that data representation in the new system is completely different from the old system.
• D. A single implementation phase is planned and the legacy system will be immediately decommissioned.

Correct answer: D

Explanation

The correct answer is D because immediately decommissioning the legacy system after a single implementation phase poses a high risk if issues arise during the migration. Options A, B, and C indicate concerns but do not present the same level of risk regarding system availability and user access after the transition.
