2. The life of software extends beyond simply developing code. Instead, it must be able to
move through the ongoing lifecycle stages, which often stop and start as needed.
Software needs to be properly monitored and maintained because it changes frequently
depending on its use. This is done in part to prepare for impending organisational
changes, but it is much more crucial now since technology is constantly evolving.
Software upkeep is essential for boosting your company's expansion. So, we have
created a piece about software maintenance. But first, let's define what software
maintenance is in its simplest terms and then discuss why it's crucial to use it in your
company.

3. What is Software Maintenance?
Before the programme is installed on a live server, you can edit or update it using the
software maintenance process.
The software must be maintained as well as developed for your company's
requirements. You must maintain thorough records of all the key features of the
software solutions you intend to use for your company.
Do you know that the global CMMS software market is estimated to reach $1.26 billion
by the end of 2026?
Bug fixes, monitoring, enhancements, and support are the four fundamental features
that define the four basic categories of software maintenance, as demonstrated above.

4. What are the Different Types of Software Maintenance?
Let’s highlight four types of software maintenance to make it easy for you to select the
best option for your software development lifecycle.
● Corrective Software Maintenance
● Preventive Software Maintenance
● Perfective Software Maintenance
● Adaptive Software Maintenance

6. 1. Corrective Software Maintenance
Corrective software maintenance is the standard and time-tested method for promptly
removing and correcting problems from existing software.
Simply said, this kind of software maintenance is in charge of finding flaws in the
current system and fixing them so that it operates more accurately. The majority of the
time, it takes the form of brief updates.
What are the best examples of corrective software maintenance?
● If you found that the software needs to be fixed as per your expectations due to
some faulty logic flow, wrong implementation, or even invalid or incomplete tests.
● Once your software is published, your end-users may face some issues.

7. 2. Preventive Software Maintenance
In order to keep the system secure against any potential vulnerabilities, preventive
software maintenance is crucial.
This kind of software maintenance often refers to software upgrades that are carried
out especially to protect the software in the future. Also, it protects your software from
any possible software modifications.
Preventive maintenance offers:
● You can easily create a document updating policy as per the existing state of the
system.
● Efficiently deal with code optimization for better software execution
● Reconstructing or reducing the code of the software to make it understandable

8. 3. Perfective Software Maintenance
You may quickly adjust all necessary components, features, and even skills to effectively
manage system operations and app performance with the use of perfective software
maintenance.
The responsiveness and usefulness of the software is the sole concern of this kind of
maintenance. By changing the functioning of the software as it is now designed, you can
rapidly make improvements, delete features, or add new ones.
Perfective software maintenance typically includes:
● Performance enhancement for your better user availability
● Enhanced user interfaces and software usability
● Better software functionality and performance

9. 4. Adaptive Software Maintenance
Adaptive software maintenance specifically addresses the compatibility strategy in
accordance with your business requirements and technical viewpoints. This software
maintenance is crucial since it manages the conversion of the system, which makes it
simple for you to rapidly respond to large changes.
Adaptive software maintenance is especially used for modifying the software when
there are following conditions.
● The operating system your software executes is evolving
● Your users generally require the product to work with new hardware as well as
software.
● The expectation of software defects will affect your customers in many ways in the
upcoming future.

10. Primary Reasons For Software To Require Maintenance
Software’s lifespan depends entirely on the system upgradation to run efficiently on the
system. So, to make it easy for you, we highlight some of the best reasons you must
follow to maintain the software on a large scale.
Michael Bolton, a prominent software testing professional says that Everybody is a
tester or can become one to some degree. I mean, we’re born testers.
1. Bug Fixing Process To Minimize Errors
2. Capability Enhancement To Improve Software Performance
3. Removal of Outdated Functionalities For Better Results
4. Improving the Software Application Performance

11. Understanding the Software Maintenance Process
The software maintenance planning method is the essential phase of the software
development lifecycle. So, it takes place in your system through standardised
management of the software maintenance process known as the Software Maintenance
Life Cycle (SMLC).
You can efficiently implement SMLC in seven different phases, as mentioned below:
Identification, Analysis, Design, Implementation, System Testing, Acceptance Testing,
and Delivery

12. 1. Identification
The first phase of the software maintenance life cycle initiates with the identification.
Before you implement any specific change in the software for the requests raised, the
modifications are first analyzed and classified according to the attention or
maintenance required.
Depending on your business needs, you can perform manual or automated software
updates.
2. Analysis
To incorporate any change in the software solutions, you need to efficiently deal with
every modification request’s practical and feasible aspects.
The analysis phase of the software maintenance process includes validated changes or
input where the modification cost is estimated.

13. 3. Design
The next phase is the designing phase, where you have to develop a new software
framework as per the pre-determined survey. Moreover, it would help if you built
testing software and that too for safety and security purposes.
4. Implementation
Now, it’s time to design and develop a new software framework by adding the codings
to your application. But, again, it depends on your business needs on how you want to
add functionality or specification to your system.
5. System Testing
The testing phase is the core part of the software maintenance process. It's mandatory
to perform the testing of every code and specification that you implemented on your
system. This phase is reliable for determining if you require any further changes or
additions are needed for the new model of software.

14. 6. Acceptance Testing
This stage of software maintenance is only handled by third-party end-users. What they
do is simply perform a “dry run test” just to verify whether the specification or
functionality is working as per the predefined modification requests or not.
7. Delivery
The delivery stage is the final phase of the software maintenance process, where the
testing phase is completed successfully by the tester. Then, the developers start to
initiate the delivering the software solutions to the end users.

15. Strategies That Make Successful Software Maintenance
What’s the main planning that you can implement for making the perfect software
maintenance? It’s identifying the techniques that drive through the solutions making a
significant impact on strategic plans.
Two essential terminologies play a vital role in maintaining your software efficiently.
● Your Software Documentation Must Be Clean
● Performing the Perfect QA (Quality Analysis) For Your Software
So, these are the major strategies you must implement before building software
solutions for your business needs. If you follow these strategies strictly, you’ll gain a
secret key to opt for successful software project delivery.

16. Conclusion
The software development lifecycle must include a process for software maintenance. It
resembles our human body exactly. There are numerous risks of developing serious
health issues if we don't take care of our bodies.
Likewise, there will be less opportunity for optimal business growth if you don't take
software maintenance into account when developing your application.
Plan accordingly to put the best methods and tactics into place to ensure a seamless
software maintenance process. Also, you can even benefit greatly from a top software
development company's wonderful assistance.
