1. Corrective Maintenance

No matter how well-built, every software can have errors or bugs. When users encounter issues like software crashes, errors, or incorrect behavior, corrective maintenance aims to diagnose the problem, understand its root cause, and implement a solution to restore its proper functionality.

Software maintenance, also known as bug maintenance, is the most common type. This type of maintenance revolves around software problem-solving – focusing on resolving problems that have been reported or discovered during the software’s usage, ensuring that it operates as intended, and minimizing troubles for users.

2. Preventative Maintenance

Preventative maintenance aims to identify and address potential issues before they occur proactively. It involves code refactoring, optimization, and regular system audits to ensure the software’s performance, stability, and security.

By conducting preventive maintenance, software teams can minimize the accumulation of technical debt, improve the codebase’s maintainability, and reduce the likelihood of future problems or failures. This approach helps optimize the software’s efficiency, reduce downtime, and enhance its quality and reliability.

3. Perfective Maintenance

Perfective maintenance enhances the software’s functionality, performance, or user experience. It involves improving existing features or adding new ones to meet evolving user needs and expectations. This type of maintenance often stems from user feedback, market research, or the desire to stay competitive.

Perfective maintenance aims to enrich the software’s capabilities, usability, and overall value by introducing new features, enhancing user interfaces, optimizing performance, or streamlining workflows. It ensures that the software remains up-to-date, relevant, and appealing to its users.

4. Adaptive Maintenance

Adaptive maintenance involves modifying the software to adapt and remain compatible with environmental changes. This may include software upgrades to support new operating system versions, hardware upgrades, browser compatibility, or compliance with evolving industry standards or regulations.

Adaptive maintenance ensures that the software continues to operate seamlessly in different contexts and remains usable as technology advances. It involves making necessary modifications, adjustments, or upgrades to ensure compatibility, interoperability, and optimal performance within the changing technological landscape.

What Is Software Support?

Software support is the assistance provided to users or customers of a software product to assist them in resolving issues, addressing queries, and ensuring the effective use of the software. It encompasses various activities to assist users in utilizing the software’s features, maintain its stability, and troubleshoot any problems.

Website and application support is vital to ensure users can effectively employ the software, resolve issues promptly, and receive the necessary guidance.

When Do You Need Software Support?

Software support is necessary for several situations and several reasons, including:

Issue Resolution: When users encounter technical issues or bugs that hinder their ability to use the software, software support offers assistance in identifying and resolving these issues and minimizing disruptions.

Technical Expertise: Software support teams have specialized knowledge and expertise in the software product. They understand the software’s architecture, features, and functionality, enabling them to provide valuable insights and solutions to users’ queries and challenges.

The Difference Between Software Maintenance and Software Support

Software maintenance and support are two distinct concepts within the software development lifecycle, although they are often related. Here’s a brief explanation of the differences between the two regarding scope, types of clients, and cost.


The scope of a software support provider is limited to addressing emergency requirements and immediate fixes for severe issues in the system. They focus on repairing software that isn’t functioning optimally, whether due to technical defaults or major bugs. They may refer clients to the software vendor or a specialized IT group if they cannot resolve the issue.

Comparatively, a software maintenance company has a broader scope. They specialize in fixing various errors in the software app and oversee functions ranging from preventative maintenance to adaptive maintenance.

Types of Clients

A software support service provider works with various clients and software solutions, including those developed in-house or by other vendors. They can help repair and make changes to the system to ensure compatibility with third-party apps.

In contrast, a maintenance company primarily serves clients to whom they have supplied the software product. They may specialize in specific industries and deeply understand the system and its functioning, making them better equipped to handle maintenance tasks.


A software maintenance company charges a regular service fee to provide ongoing support, implement new features, remove irrelevant functions, and fix errors. This fee is often higher due to the continuous involvement and long-term commitment required.

On the other hand, a software support provider typically charges a reasonable rate for fixing minor errors on an incident-by-incident basis. Some companies may still quote a high price for support services, but payment is generally based on specific incidents. The maintenance company charges a fixed monthly fee regardless of how often their services are required or the specific support provided.
