ITPEC IP October 2022 Question 48
ITPEC IP October 2022 — Question 48 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 fixes, adaptations to environmental change, performance improvements, and preventive changes.
Answer (d)
Why not others:
- tuning during system testing is still development
- fixing a fault found during acceptance occurs before acceptance is complete
- adding a missing function during unit testing is development work
Key rule: The timing matters: changes to operational, delivered software are maintenance; pre-release corrections belong to development.
