ITPEC IP April 2021 Question 49
ITPEC IP April 2021 — Question 49 of 100
Modifying software after a defect is reported in the production system is software maintenance. Maintenance begins after delivery and operation and includes corrective changes for defects, adaptive changes for environment changes, perfective improvements, and preventive modifications.
Answer (d)
Why not others:
- tuning during system testing occurs before release
- fixing a defect found in acceptance testing is still part of pre-release development and acceptance
- adding a missing function during unit testing is implementation correction
Key rule: Changes made to operational, delivered software belong to maintenance.
