Which statement related to impact analysis is correct?

Impact analysis is a crucial process in software testing, particularly during the maintenance phase of a software project. It involves assessing the potential effects of changes made to the software, which can help in understanding what parts of the system may be affected by those changes.

The correct statement emphasizes that impact analysis is indeed valuable for regression testing during maintenance. When code is modified—whether it be through bug fixes, enhancements, or other updates—impact analysis enables testers to identify which existing functionalities or features might be at risk of being unintentionally affected. This allows for more focused regression testing, ensuring that changes do not adversely impact other parts of the system that are not directly related to the change.

This understanding of dependencies and potential impacts is vital in maintaining software quality, as it helps prioritize testing efforts where they are most needed, thus contributing to better resource management and risk mitigation in the testing process.
