Certified Information Systems Auditor (CISA) — Question 335

During the implementation of an upgraded enterprise resource planning (ERP) system, which of the following is the MOST important consideration for a go-live decision?

Answer options

• A. Post-implementation review objectives
• B. Business case
• C. Rollback strategy
• D. Test cases

Correct answer: C

Explanation

The rollback strategy is crucial because it ensures that there is a plan in place to revert to the previous system if the implementation encounters significant issues. While post-implementation objectives, the business case, and test cases are important, they do not directly address the immediate risk management needed during the go-live phase.
