The Relevance of Perfective Software Maintenance

Perfective maintenance includes speed optimization, enhancing software usability, improving user interfaces, improving software performance, and enhancing software functionality. The key points regarding perfective maintenance involve enhancing software functionality through the implementation of changed or new user requirements. The changes don’t have to be necessitated by faults, defects, or errors. Perfective maintenance is often initiated by the feedback received from customers. Half of all software maintenance activities are perfective. The modification of an Enterprise Resource Planning (ERP) program to entail a payment feature into the software system is an example of perfective maintenance. Perfective maintenance focuses on the evolving features and requirements of a system. Users may notice gaps in a system and suggest new features to the system. Perfective maintenance enhances the experience of users and removes the features that are not functional and effective.

Perfective maintenance entails implementing changed or new user requirements. It involves enhancing the system for better system performance even when such changes are not provoked by any system faults. It may include enhancing the efficiency and functioning of code and functionalities as suggested by users. There are other categories of software maintenance. They include corrective, adaptive, and preventative maintenance. Corrective maintenance solves faults and errors in the system. The task is required when software does not work as expected due to issues, such as incorrect implementation, the faulty flow of logic, incomplete, or invalid tests, etc.

Adaptive maintenance seeks to modify and update software under the following circumstances: When the platform where the software functions changes due to laws, rules, policies, operating system, etc. Adaptive maintenance also takes place if the product needs changes to interface with new software or hardware and when there are predictable defects that could affect customers in the future. Preventative maintenance entails changes that prevent errors from happening in the future. It helps to maintain the software by alleviating complexity. The tasks may involve code optimization or code reconstructing. Code optimization entails modificatio0ns that speed up program execution. It may also entail using storage space efficiently.
