Maintenance & Support Services Muzaffargarh

Software maintenance can be broken down into four main categories:

1. Corrective MaintenanceOften referred to as “bug” maintenance, corrective maintenance can be defined as correcting user reported errors in source code. This is the most urgent type of software maintenance, but, unlike support, focuses on low priority “bugs” and is commonly regarded as triaging enhancement requests rather than fixing defects.
2. Preventive MaintenanceAs its name suggests, preventive maintenance is the practice of taking preventive measures to ensure software continues running as it should. Preventive maintenance focuses on decreasing the likelihood of unanticipated effects of evolving operating systems and devices which the software runs on.
3. Perfective MaintenanceFocused on iteration, perfective maintenance is defined as engineering after delivery in order to elevate the functionality and/or performance of the software. Spurred by user feedback, perfective maintenance accounts for the implementation of new features based on user submissions.
4. Adaptive MaintenanceAdaptive maintenance is characterized by the need to alter code in one part of the software due to external problems in another part of the system. Adaptive maintenance is required when issues are caused by changes to the operating system, software dependencies, hardware, or business policies of a product, thus requiring changes to the codebase.
