Softwaremaintenance is the process of modifying a software system or component after
delivery to rectify faults, improve performance or adapt to a changed
environment. It is a set of activities performed to keep the software
functional and behavioural for as long as possible. Steps are carried out to
keep the software up-to-date and bug free after the implementation of the
software. Experts from Nexsus Techno Solutions Pvt Ltd are giving you four major
reasons to opt for software maintenance.
· Adaptive
Reasons – A software ecosystem constantly changes and regular
maintenance is required to help it adapt to the new changes.Work patterns,
compilers, software platforms, hardware upgrades andall other such things
affect the working of software. Adaptive maintenance is necessary to keep your
software latest along with long lifespan.
· Corrective
Reasons – Maintenance is carried out to repair the
prevalent faults in the software which involves fixing of bugs due to bad code
or major system repairing. Bugs may also appear in case of change in the
hardware, operating system or other accompanying parts in the system. Corrective
maintenance includes testing to detect a problem and injecting a fix without
disturbing the rest of the system.
· Perfective
Reasons – Software maintenance is performed to fine
tune the performance ability, usability and functionality of the software. It
can simply vary from changing the GUI of the software to make it more user-friendly
and attractive to making drastic changes in the core code to improve the
run-time and performance. Perfective maintenance accounts for around 60 per cent
of the maintenance cost.
· Preventive
Reasons – Preventive maintenance is essential precaution
against problems that may occur in future. An engineer can take decisions to
re-engineer the software through data and code restructuring by prudently
observing the conditions in the ecosystem. Preventive maintenance does not
really contribute to the functionality of the software but rather prevents problems
and additional repair costs that come with them.
