Most of the organizations rely on custom software solutions and apps to streamline their processes and improve efficiency.
However, just having these apps and software solutions developed once doesn't end the investment that they need to make in order to keep them running as they're supposed to.
Software is a model of the real world. When the real-world changes, the software require alteration wherever possible. Software Maintenance is an inclusive activity that includes error corrections, enhancement of capabilities, deletion of obsolete capabilities, and optimization.
Therefore, application maintenance isn't related to just fixing any defects that the software might have. It also entails proactively adding functionality and improving performance of existing applications as and when required.
Software Maintenance is needed for:-
Thus the maintenance is required to ensure that the system continues to satisfy user requirements
Corrective maintenance aims to correct any remaining errors regardless of where they may cause specifications, design, coding, testing, and documentation, etc.
It contains modifying the software to match changes in the ever-changing environment.
It is the process by which we prevent our system from being obsolete. It involves the concept of reengineering & reverse engineering in which an old system with old technology is re-engineered using new technology. This maintenance prevents the system from dying out.
It defines improving processing efficiency or performance or restricting the software to enhance changeability. This may contain enhancement of existing system functionality, improvement in computational efficiency, etc.
Regardless of the type of maintenance being performed, the software maintenance process follows the following steps:
