CISA Practice Question: Information Systems Acquisition, Development, and Implementation
During an ERP implementation, the project team decides to customize the software to align with existing business processes. Which of the following risks is MOST likely to increase as a result of extensive customization?
⚠ Common exam trap
Candidates often confuse customization with configuration; customization modifies source code or adds custom objects, while configuration uses built-in parameters, and only customization significantly increases upgrade costs.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Higher costs for future upgrades
Extensive customization of an ERP system typically involves modifying the core code or configuration beyond standard parameters. This creates a custom code base that diverges from the vendor's standard release, making future upgrades significantly more complex and costly because each upgrade requires re-applying and testing all customizations against the new version, often requiring specialized skills and extensive regression testing.
