What Are the 4 Types of Software Maintenance & Why Are They Important?


September 22, 2021


Today’s computer technology increases productivity and a variety of other things. Software maintenance keeps your software updated, so you have access to new features as well as fixes to any issues the previous software version had. Here is more about software maintenance, its benefits, and the negative results of neglecting to maintain your software.

What Are the Four Categories of Software Maintenance?

There are four categories of software that help ensure the software as a whole operates as intended.

Corrective Software Maintenance

Corrective software maintenance is also referred to as bug fixing. This type of software maintenance involves flaws in the code, design, and logic of the software. Corrective software maintenance is the delivery to correct faults. This system maintenance makes the software easier to use. When your software is not performing as it should, the reason could be it requires one or multiple updates because there are flaws with the software development. If corrective maintenance tasks consume most of your time, consider focusing on:

  • Developing high-quality code
  • The proper implementation of the specifics of the software’s design
  • Adopting a robust testing practice
  • Enhancing your skills to predict problems

If you notice and repair flaws in the software before users do, preventive or adaptive maintenance is suitable. However, if you make the necessary software adjustments after receiving bug reports from users, taking corrective maintenance action is best.

Adaptive Software Maintenance

Adaptive software maintenance helps you update and modify software when the software’s platform changes because of policies, technology, laws, or operating systems. This type of maintenance also helps when a user needs the software to interact with new software or hardware, or you predict software defects that will affect future customers. Suppose your goal is to change the software’s environment. In that case, there will be additional changes with another part of the software, such as the processors, updates, compilers, and the overall functionality of the software.

Perfective Software Maintenance

Perfective software maintenance occurs when you update the software’s system to make it more valuable by meeting the user’s needs. When you invest in this type of software engineering, you aim to:

  • Improve performance
  • Increase optimization speed
  • Improve software usability
  • Improve user interfaces
  • Enhance software functionality

This perfective maintenance process accounts for more than 45% of maintenance activities and is often initiated by customers' feedback.

Preventive Software Maintenance

Preventive maintenance occurs when you change the software to prevent future errors. Different preventive maintenance tasks include reconstructing and optimizing the code and updating the documentation. This type of maintenance enhances software maintainability by reducing challenges and other complexities.

The Importance of Software Maintenance

Maintaining your software product is a form of corrective maintenance that enables you to expand the software's life cycle by completing various tasks.

Bug Fixes

Things go wrong, and that’s okay, but when things go wrong with your software, you need to make changes to ensure the software performs at optimal levels. Many bug fixes include issues with code, design, or the overall product that may need to be revamped. Sometimes a bug fix can be as simple as changing one part of the software’s engineering, and other times you may need to invest more time into the development of the software.

Improved Performance with Regular Upgrades

Regularly upgrading a software product gives users more control. Upgrades are a part of perfective maintenance. Regular updates are an essential part of software security and the overall maintenance process. These updates help keep the software running as smoothly as possible.

Adapt to a Changing Environment

If there’s one thing you know about technology, it's that it’s continuously changing. Your software needs to keep up with the changes and remain relevant. Sometimes when a software’s environment changes, you have to make major changes, and other times, minor changes suffice. Regardless of the changes, you have to make, changes are necessary to ensure the software remains functional.

Predictive Cash Flow

With predictive cash flow, you learn how to turn your IoT into action by using intelligent analytics. Predictive cash flow gives you power when you understand your business's health by helping you mitigate risks before they become significant issues.

What Does Software Maintenance Include?

Software maintenance is an umbrella term that describes different steps that are taken to improve the development of software. This software engineering process can include:

  • Error correction
  • Deletion of obsolete capabilities
  • Optimization
  • Capability enhancements

Maintaining software for any system is essential for adapting to change as time progresses.

How Do You Maintain Software?

Software maintenance is a crucial aspect of deploying any type of software product. The key to success is letting your users guide you with their feedback. You should also continuously update your software and ensure it includes new features. Consider different rights reserved that state the terms and other clauses that inform users of what you expect of them and what they can expect from your software.

Software maintenance will never be a thing of the past. Make sure you do everything you can to ensure your product is beneficial by being a solution that can solve different problems.
