In software engineering, software maintenance is the modification of a software product after delivery to correct faults, to improve performance or other attributes.
A common perception of maintenance is that it merely involves fixing defects.
However, one study indicated that over 80% of maintenance effort is used for non-corrective actions.
This perception is perpetuated by users submitting problem reports that in reality are functionality enhancements to the system.
More recent studies put the bug-fixing proportion closer to 21%.
