Why Software Maintenance is Essential for Business?
                     
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.
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.
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

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.
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
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
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.
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
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
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.
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.
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.
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.
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.
