How Software Maintenance Enhances the Performance of Software Systems

Perfective maintenance helps to optimize software speed, improve user interfaces, enhance software usability, improve software performance, and enhance software functionality. Perfective maintenance involves enhancing software functionality through the implementation of changed and new user requirements. The changes made are not necessarily prompted by faults, errors, or defects. The maintenance process is often (but not always) initiated through customer feedback. Perfective maintenance makes up half of all maintenance activities. Perfective maintenance may include ERP (Enterprise Resource Planning) program modification to include new payment features in the software system. There are many reasons why software maintenance is necessary. The maintenance process fixes errors and bugs in software systems. It also enhances the functionality of the software. Products can become more compatible with the latest business and marketing environment through software maintenance. Software maintenance removes outdated functions inhibiting the efficiency of a product. It also enhances software performance.

Software defects could arise due to faults and errors in the logic, code, and design of the software. Corrective maintenance is an action that solves the faults and errors in the software system. Corrective changes should happen if the software stops working as expected as a result of acute issues, like incorrect implementation, faulty logic flow, incomplete and invalid tests, etc. Corrective maintenance should also happen if software issues start affecting users after the release of the software. Adaptive maintenance seeks to modify and update software under different circumstances. Adaptive maintenance happens if the platform under which the software operates changes due to changes in policy, rules, laws, technology, and operating system. It also happens when customers need products to interface properly with new software or hardware. Predicted defects in software that could affect customers in days to come can necessitate adaptive maintenance.

Preventative maintenance is a change you make to software to avoid the occurrence of errors. It enhances software maintainability through the reduction of complexity.
