Software maintenance is a vital step in the software development process. The primary objective of maintenance is to change and update software programs after they are delivered to repair defects and enhance performance. 

This article from Eximias – one of the best software development providers, will accompany with across the journal to help you find out how vital software maintenance is and why you need that so far.

What is software maintenance?

Software maintenance is one of the most crucial steps of the software development process, also known as the Software Development Life Cycle (SDLC). This process occurs only when the product has been completed and delivered to the customer who ordered the software product. 

During the early phases of deployment, software engineers assist in monitoring client feedback. After that, they will create optimal software updates in terms of code, interface, user experience, software bug fixes, and more. 

Although it is the last step in the SDLC, it takes the longest time. How long the maintenance period lasts depends on the policy of each software development business and the package that the customer has chosen.

Why is software maintenance so important?

The software can be the latest model this year but it could be outdated and full of bugs in the following year. Software maintenance is an effective way for businesses to implement new technologies and features, limit errors and improve business efficiency.

On the customer side, the software development business, which includes providing maintenance packages after completion, is similar to taking care of customers after purchasing the product. Not only does this help customers feel cared for, but it also provides a sense of security and reliability when they use custom software.

What are the 4 types of software maintenance

Software is a human-made product, the occurrence of errors during use is an inevitable thing. Currently, there are four types of software warranties associated with user needs and software optimization, which include:

  • Corrective software maintenance
  • Preventive software maintenance
  • Perfective Software Maintenance
  • Adaptive software maintenance

1. Corrective software maintenance

When software’s issues arise, you must resolve them, the mistakes can substantially impact the internal system. Even more, they can influence the layout and interrupt the business’s working process. Software errors must be correct quickly to avoid such unanticipated losses. 

When a user finds a bug, they must promptly tell the program maker to fix it. Developers should continually monitor published software and products to detect, fix problems and release proactive updates to repair issues and enhance the user experience. In that manner, users will have more confidence and peace of mind.

2. Preventive software maintenance

Prevention is one challenge for developers to identify and avoid future dangers. The ultimate objective is to have the program last as long as possible. The maintenance modifications are preventative since they prepare for future changes.

It involves optimizing the code for scalability and maintenance, as well as maintaining your old material. Additionally, it includes identifying and resolving latent defects in the product before it manifests as operational faults.

3. Perfective Software Maintenance

When the program is made available to the public, new challenges and ideas emerge. Users may recognize the need for additional features or requirements in the program to be the greatest tool available for their needs. It is at this point when perfective maintenance comes into play.

Perfective maintenance seeks to improve the software by introducing new features and eliminating features that are no longer relevant or useful in the supplied software. This approach ensures that software remains relevant as the market and user demands evolve.

4. Adaptive Software Maintenance

The technological environment is constantly changing day by day. Maybe the technology you use today will be obsolete tomorrow. Adaptive maintenance helps the technology you’re using to adapt to these changes. 

Some software products that are not optimized to system will cause operation issues. It will affect the smooth operation of the hardware later on. Learning how to optimize software and hardware together will significantly reduce the impact on your business’s system.

Before the impact of changes in technology, cybersecurity laws, the internal factors and the social environment. The software you are using must change to meet those requirements and update the latest technologies to optimize work efficiency.

The maintenance process

As mentioned, maintenance is a two-way process. Therefore, maintenance usually takes a lot of time and happens periodically according to specific plans. Most of the process models involve the following steps: 

  • Identify bugs: When a client reports a bug, or the product development team discovers an error during a system inspection, the team will identify and record the problem. After that, they will launch a patch for the system.
  • Analysis: The process of reviewing proposed modifications, including understanding the potential consequences of the change. This step usually involves a cost analysis to see if the change is financially worthwhile.
  • Redesign and making upgrades: These are all the analysis documents about the problems compiled from the previous step that will be identified and designed by the programming team, like fixing bugs, upgrading, and releasing new updates.
  • System testing: The software and the entire system, along with the module itself, must be tested before release.
  • Acceptance test: This is a crucial step where the user checks the modification for acceptance. They can identify current issues and make suggestions for more effective implementation and change.
  • Distribution: This is when the development team updates the program or, in certain instances, installs new software to provide the client with the necessary modifications.


Software maintenance can be a complex and time-consuming activity that requires the initiative of the two parties: the developer team and the user. Detecting and correcting errors in early phases will minimize unwanted losses and improve the customer experience.
