The blog emphasizes its significance by highlighting how regular maintenance enhances user experience, minimizes downtime, and supports continuous innovation, making it essential for organizational success in today's fast-paced technological landscape.
“Software is Eating the Whole World!”
The above phrase is rightly said by the co-founder of venture capital firm Andreessen Horowitz, Marc Andreessen. Well, isn’t he right, absolutely?
If your business utilizes the software for the core operations, then your business cannot stand apart without software maintenance – upgrades, support, and updates. It’s always required to keep your software updated in today’s time with comprehensive software services.
In fact, maintaining software is no less important than developing software. It keeps solutions athletic to deal with developing technology and the business environment.
Conventionally, IT service providers suggest their consumers to go for software maintenance services for the enhanced and steady performance of the system. When it comes to software, 60% costing is abide for maintenance and from total software maintenance cost, 60% is for solution enhancement, as per the writer of the ‘Facts and Fallacies of Software Engineering,’ Robert Glass.

Information Technology is one of the most refurbished domains of the industry. It acknowledges technical advancements continually that improve the efficiency of problem-solving to streamline business operations. To lead the market, it’s necessary to adopt the latest enterprise software development trends and outrun the competition. The system is updated with upgraded and smart technologies on a regular basis and runs seamlessly with high-end efficiency under maintenance management.
At intervals, system maintenance involves advancement in the existing solution as there are requirements of new software development as per the market shift.
Software maintenance enhances the growth of your software. Hence, in this article, we will discuss software maintenance types, processes, maintenance costs, and key strategies to ensure that your software succeeds.
“Software Maintenance is the process of modifying, changing, and updating a software system or module to resolve errors, improve performance, or adapt to a changing environment.”
Software maintenance is one type of process, which helps to upgrade, modify, and update software to stay up with client needs. Software maintenance is performed for a variety of purposes, including improving the software overall, addressing faults or bugs, increasing performance, and more, once the software is released or launched.
Software maintenance is known as the modification of a software product after it has been delivered to rectify flaws, improve performance, or other features, in terms of software engineering.
If we talk about computer software maintenance, it’s a vast management process and part of the SDLC – Software Development Life Cycle. The primary goal of software maintenance in software engineering is to modify and update software applications after deployments to fix bugs and improve system performance. The software maintenance processes take place once the software is developed or deployed. Hence, it enhances the software performance by eliminating errors, removing unusable development, and implementing advanced development strategies.
However, maintaining software is not only the scenario of the post-development process. Apart from making your software error-free, you have to make sure that the software is secure and scalable. Your software may become outdated if you don’t constantly upgrade it with new features and resolve bugs. You may feel that the software is running smoothly; thus, it doesn’t require any IT software maintenance. But you are wrong here! The role of a solution architecture for software development has changed in today’s time, and 2025 is ready to experience a new language and technology.

There are four different software maintenance types, which are defined for various reasons and purposes. A software product may have to undergo one or more types of maintenance throughout the software maintenance life cycle.
Adaptive software maintenance is the process of conversion in the system to keep the software compatible with changing business needs and technical evolution. This software maintenance type primarily focuses on software frameworks. It is made in response to new operating systems, platforms, and hardware to retain continuity with the software.
Adaptive software maintenance is about changing software in response to changes in its environment.
The primary goal of adaptive software maintenance is to update and modify the software when:
Perfective Maintenance is a process of modifying all elements, functionalities, and abilities to enhance system operations and performance. The software’s receptiveness and usability are solved by perfective software maintenance. It includes altering current software functionality by improving, removing, or inserting new features or functions.
Perfective software maintenance activities focus on functional enhancements to improve the user experience.
If you want to update the software system to improve its value as per the user requirements, you can execute the perfective software maintenance. This includes:
Identifying errors in the existing solution and correcting them to make it works more accurately. This software maintenance activity aims to eliminate and fix bugs or issues in the software. Corrective software maintenance is usually done in the form of small updates frequently.
In a nutshell, corrective software maintenance occurs when there are errors and faults in logic, code, and design.
Corrective software maintenance is about correcting software bugs, errors, and defects.
You can implement corrective software maintenance techniques when:
Preventive software maintenance service helps in preventing the system from any forthcoming vulnerabilities. Preventive maintenance defines improvements of the software, which is done to safeguard the software for the future. It is carried out to prevent the product from any potential software alteration.

In the life cycle of enterprise software development, a software maintenance plan is a very crucial phase. Hence, it is executed in the system through a well-planned software maintenance process which is known as Software Maintenance Life Cycle (SMLC). SMLC or the maintenance phase of software development life cycle is implemented in seven different phases. Those are:
As the name goes, in this phase of the software maintenance life cycle, the modifications are ‘identified’. Before implementing the changes for the requests raised, the modifications are first analyzed and classified according to the attention or maintenance it requires. This phase can be automated or manually done by a user.
In this maintenance phase of software development life cycle, the practicality and feasibility of each verified modification request are planned to incorporate changes in the software. The analysis includes validated changes or input where the cost of modification is also estimated.
The new framework of the software is determined according to the result of the analysis. Survey or test software is also developed for the purpose of safety and security.
This is where the main or new software framework is implemented; as in, the codes are crafted, and in the new support system, specifications are added.
In this testing, the implementation of codes and specifications are tested. This stage determines if any further changes or additions are required in the new model of software.
This stage is performed by third-party end-users. They run a dummy software test, also known as a dry run test, to check if the implemented specifications are working properly, which was mentioned in the modification request.
As and when the testing phase is cleared and the developers get a green signal from the third-party users, they deliver the software to the primary users.

The cost of the specific software can be categorized into three different components: Software License, Software Maintenance, and Implementation Services.
But if we consider the cost of software maintenance, it is categorized into two parts.
The non-technical factors include for average software maintenance cost are:
Team Stability: When a new team member joins the dedicated software development team, it takes some time to get his hands on the software development process. Therefore, it becomes quite difficult to make changes to the software. This will add a cost to the software maintenance.
Software Lifecycle: When software becomes obsolete, the original hardware is changed, and the conversion cost exceeds the rewriting cost.
Dependent on External Environment: When software is dependent on the external environment, it must be modified whenever the external environment changes.
Hardware Stability: Software maintenance expenses are reduced to zero if the software executes on a specific hardware configuration that does not change during the entire software lifecycle. However, this is a rare occurrence due to ongoing hardware development.
The technical factors include for average software maintenance cost are:
Module Independence: The ability to update any software block in the system without impacting the others.
Programming Language: Software written in a high-level programming language is generally easier to understand than written in a low-level language.
Programming Style: The developer's writing method determines the ease of updating and understanding software.
Program Validation and Testing: The more time spent evaluating the design and testing of the software, the fewer bugs it contains and the lower the cost of software maintenance. The cost of resolving errors is determined by the type of error. Errors in software requirements are the most expensive.
Documentation: A clear and complete documentation will bring down the maintenance cost.
Configuration Management Techniques: Keeping track of system documentation and ensuring uniformity is one of the costs involved. This means that good configuration management can help you save money.
The process usually costs up to two-thirds of the entire software process or even more than 50% of the SDLC processes on the whole.
Why? This is because if, for instance, the software is old, the maintenance cost will be high too. So, it may happen that developers may not be 100% successful in targeting the exact issues. This will result in enormous hours being spent at work.
However, on a positive note, estimating software maintenance costs can, in fact, be brought down by following the below steps.
Abiding by these steps will help you in bringing down the software maintenance costs to a great extent.
Now you may have got an idea about the costs you may have to incur to maintain the software. Now, you must be wondering what strategies to follow to make the software maintenance process easier.
To throw light on this area, we present below the following approaches. This will make the process seamless and help you save costs.

After having a thorough understanding of what is software maintenance, your organization must maintain software regularly to prevent fatal incidents and save costs. Moreover, you will come across some significant challenges in software maintenance, which are:
There are two main techniques or strategies that we should consider for successful software maintenance in software engineering. For that, you can reach out to the prominent software development outsourcing company - Radixweb to implement given key strategies.
Here, we are going to explain some concepts behind the software maintenance strategy.
Review Your Documentation - The process involves containing information related to code operation. In addition, it also includes solutions to problems that may occur in the near future. This makes the task of upgradation considerably easier.
Software Maintenance Process Automation - The process of software products doesn’t end after the development. There may be a time when some risks or issues may arise that you have not thought of before. Hence, making your software future-proof to manage any risks is essential.
Automating the software maintenance process will help add value to your business by saving time and maintenance costs. You can achieve higher productivity and profitability with automation for code reviews and production monitoring. Moreover, it makes your product market-ready without increasing the workforce.
Adopting Cloud Migration Solutions - The primary advantage of adopting this software maintenance strategy is to reduce constant maintenance costs. Migrating your software to the cloud offers robust security, scalability, reliability, and data management benefits.
Implement New Infrastructure - Sometimes, your software product infrastructure grows organically without a specific roadmap or plan. Well, you can overcome these software maintenance challenges by analyzing and optimizing your existing infrastructure.
While maintaining your customized software product, you can easily replace some application parts with generic SaaS solutions. As a result, it will help you with cost reduction in the long run.
Invest in QA (Quality Analysis) - Before making software live, it has to pass through multiple software testing phases. QA process takes place to eliminate bugs, errors, and run-time issues. The QA process can be integrated either before the launch or during the planning stage itself. This will make sure to deploy software without any errors or bugs. You can also get an insight into the necessary changes that need to be made.
As we explain software maintenance, its cost and the software maintenance activities in software engineering to bring it down completely, it is worth describing the different models of this process too.
It will help you to a great extent in modifying the overall codes and fixing glitches even before they occur, so as to say. This way, you can hold the secret key to successful software project delivery.
There are many software maintenance models, but the most important models are:
Just how it sounds, the main aim of this model is to search for glitches and fix them as soon as possible. The main advantage of the quick-fix model is that it works very rapidly at a low price. The approach of this model is to modify the coding with minimal consideration.
The primary nature of the changes in this model is iterative. Based on the analysis of the existing system, the changes are incorporated in this model. It requires complete documentation of the software that is available before making any changes.
In this model, the part of the existing system that is in the position of using is identified; hence it is called the ‘re-use-oriented model’. After analyzing, this model goes through changes or enhancements as required.
Software reengineering refers to updating the existing software without changing its functionality. The code is rewritten, and the software design is changed during this process.
Moreover, sometimes, it’s not easy to implement the latest technologies with your existing software. It becomes a tedious process if the hardware becomes obsolete.
Re-Engineering Process
However, there are a few terms involved in software engineering that you should be aware of:
Reverse Engineering
Reverse Engineering is a process of implementing system functionalities by analyzing and understanding the existing system. It can be considered a reverse SDLC model that examines lower abstraction levels to reach a higher abstraction level.
In the reverse engineering process, our designers examine the code to discover the design and draw conclusions about the specifications. As a result, they work backward from system specification to code.
Program Restructuring
Program Restructuring is a process of reconstructing and restructuring existing software. The source code is rearranged, either inside the same programming language or between computer languages. The program restructuring consists of source code restructuring and data restructuring.
Restructuring improves stability and maintainability without ever affecting the software's functionality. It allows you to modify or upgrade program elements that commonly result in errors. Moreover, restructuring enables you to get rid of software dependencies on outdated hardware platforms.
Forward Engineering
Forward Engineering is a process that’s used to create required software from the specifications already in place that were created through reverse engineering. It makes the assumption that prior software engineering work has been completed.
One prime difference between the software engineering process and forward engineering is that forward engineering happens after reverse engineering.
You can leverage following advantages of software maintenance:
ConclusionSoftware maintenance is not an option; it is a must. You can consider your vehicle, for example. If you don’t maintain your vehicle, it may cause many problems often. Also, the bill for unperformed vehicle maintenance will cost you higher than the regular inspection or maintenance.
