Corrective Maintenance
- Purpose: To fix any bugs that are found in the system
E.g. reports truncate some text; E.g. 31 is able to be entered as a day for June; E.g. the system ‘crashes’ / ‘hangs’ intermittently
Consequences
-
- If corrective maintenance takes place: The system will run more accurately; Integrity of data can be maintained; Users will be happier using the system
- If corrective maintenance does not take place: Errors will continue to occur; The integrity of data could be compromised; Users will become frustrated with the bugs in the system; The system will not be as productive as it should (efficient)
Perfective Maintenance
- During reviews, suggestions may be made that will improve the system: These are not ‘corrections’; They are ideas to make the system run better; They may be enhancements or new features
