The Different Categories and Meanings of Software Maintenance

The purpose of software maintenance is to improve software performance and correct any faults after the product has been delivered to a customer. Software maintenance is necessary because it fixes errors and bugs in software systems. It also improves the efficiency of software and makes the product compatible with the latest business and marketing environments. Software maintenance removes outdated product functions that inhibit product efficiency. The process also enhances software performance. There are different categories of software maintenance as discussed below. Corrective maintenance solves faults and errors in the software system. Software defects arise from faults and errors in software logic, code, and design. Corrective changes are necessary when software is not functioning as it should due to acute issues like incorrect implementation, the faulty flow of logic, and incomplete or invalid tests.

Adaptive maintenance seeks to modify and update software under different scenarios. It happens when the platform on which software operates is evolving due to policies, technology, operating system, rules, and laws. A product should interface with new software or hardware. Predictable software defects that could affect customers can be resolved through adaptive maintenance. Note that if modifications of the software environment occur, it might trigger changes within software components as well. For instance, updating processors, servers, and compilers can affect software functionality. Perfective maintenance happens when software systems get updated to enhance their value as per the demands. It may entail enhancing software functionality, improving software usability, enhancing user interfaces, and improving software performance.
