Corrective Software Maintenance
Corrective software maintenance addresses bugs and errors in your software that can impact its design, code and logic. Usually, these errors and faults are identified through bug reports created by customers or users. However, corrective software maintenance will uncover software issues before your customers do, which helps you maintain your organisation’s reputation.
Adaptive Software Maintenance
Adaptive software maintenance crucial when changing your software’s environment. Changes can occur to the environment due to the hardware, cloud storage, software dependencies or even changes within the operating system itself. Changing payment processors, updating services or modifying vendors can all necessitate adaptive software maintenance.
Perfective Software Maintenance
Perfective software maintenance focuses on improving features and requirements within your software. This type of software maintenance is centred around improving your user’s experience by adding new, essential features and removing ineffective ones. The features that are removed can include those that do not meet your end goals, as well as those that go unused.
Preventive Software Maintenance
Preventative software maintenance ensures that your software is continually changing and adapting, which allows it to continue working for a longer amount of time. This prevents your software from becoming obsolete, as it continues to adapt and change. Preventative software maintenance can include optimisation of code and updating documentation as necessary.
