ITPEC IP October 2024 Question 47
ITPEC IP October 2024 — Question 47 of 100
Modifying software after a defect is reported in a production system is software maintenance. Maintenance begins after software has been delivered and placed into operation. Corrective maintenance removes discovered faults; other maintenance categories may adapt software to environmental changes, improve maintainability or performance, or prevent future problems.
Answer (d)
Why not others:
- (a) tuning during system testing occurs within development before production operation
- (b) correcting a defect found by an acceptance test is still part of the pre-acceptance development and delivery process
- (c) adding a missing function during unit testing is also development-stage work
Key rule: The distinguishing point is operational use: changes made to delivered software running in production are maintenance.
