Software maintenance
Software maintenance is an important aspect of the software development life cycle (SDLC), as it ensures that software programs continue to run properly and satisfy the changing needs of the business. Software maintenance is an important process in ALM (Application Lifecycle Management) and DevOps that helps to ensure that software is continuously updated, maintained, and enhanced over time.
ALM and DevOps are concerned with continuous software delivery and the use of automation tools to speed up the software development process. This includes using automated testing, continuous integration, and continuous deployment to ensure that software is built and distributed as quickly and efficiently as possible.
One of the primary advantages of ALM and DevOps software maintenance is that it helps to ensure that software is always up to date and working efficiently. This can help to avoid downtime and guarantee users have access to the most up-to-date features and capabilities.
Another advantage of ALM and DevOps software maintenance is that it can help to improve the quality of software applications over time. Developers can find and repair bugs and performance issues before they become serious problems by continuously monitoring and enhancing the product.
Furthermore, ALM and DevOps software maintenance can help to lower the expenses associated with software development and maintenance. Developers can save time and resources by automating the maintenance process, as well as reducing the possibility of faults or mistakes in the product.
Overall, software maintenance is an important process in ALM and DevOps since it helps to ensure that software applications are constantly updated, maintained, and enhanced over time. Developers can save time, cut expenses, and improve the overall quality and performance of software systems by leveraging automation technologies and processes.

What is software maintenance?
Software maintenance is the process of modifying, updating, and improving software to ensure that it continues to meet the desired requirements and quality standards over time.
Why is software maintenance important?
Software maintenance is important because it helps to keep software up-to-date, ensure that it continues to meet the needs of users and stakeholders, and reduce the risk of software failure.
What are some common types of software maintenance?
Some common types of software maintenance include corrective maintenance (fixing defects and errors), adaptive maintenance (updating software to accommodate changes in the environment), perfective maintenance (improving software performance and usability), and preventive maintenance (taking proactive steps to prevent future problems).
What is the difference between software maintenance and software development?
Software maintenance is focused on modifying and improving existing software, while software development is focused on creating new software from scratch.
What are some common challenges of software maintenance?
Common challenges of software maintenance include maintaining the integrity of the software, dealing with technical debt, managing the complexity of the software, and ensuring that maintenance activities do not introduce new defects or errors.
What is a software maintenance plan?
A software maintenance plan is a document that outlines the goals, objectives, scope, and resources of a software maintenance project. It helps to ensure that maintenance activities are planned, organized, and executed effectively.
What is regression testing in software maintenance?
Regression testing is the process of retesting software after modifications have been made, to ensure that the modifications have not introduced new defects or errors.
What is the role of documentation in software maintenance?
Documentation is important in software maintenance because it provides a record of the software's design, functionality, and maintenance history. This can help developers and maintainers to understand the software better, identify potential problems, and make informed decisions about maintenance activities.
What is a software maintenance release?
A software maintenance release is a version of software that includes bug fixes, minor updates, and other modifications that are intended to improve the software's performance, reliability, and usability.
What is the difference between corrective and adaptive maintenance?
Corrective maintenance is focused on fixing defects and errors in software, while adaptive maintenance is focused on modifying software to accommodate changes in the environment, such as changes in hardware, operating systems, or business processes.

- Snippet from Wikipedia: Software maintenance
Software maintenance is the modification of software after delivery.
As per the IEEE standard glossary of software engineering terminology, software maintenance refers to the process of modifying and updating software after its initial development and deployment, to correct faults, improve performance or other attributes, add new features to meet evolving user requirements, or adapt to a changed environment. It is important to emphasize that software maintenance thus involves many activities that go beyond mere bug fixing. Software maintenance is an ongoing process that is essential for the longevity of a software system, to keep it effective, adaptable and relevant in an ever-evolving technological landscape.
Software maintenance is often considered lower skilled and less rewarding than new development. As such, it is a common target for outsourcing or offshoring. Usually, the team developing the software is different from those who will be maintaining it. The developers lack an incentive to write the code to be easily maintained. Software is often delivered incomplete and almost always contains some bugs that the maintenance team must fix. Software maintenance often initially includes the development of new functionality, but as the product nears the end of its lifespan, maintenance is reduced to the bare minimum and then cut off entirely before the product is withdrawn.
Each maintenance cycle begins with a change request typically originating from an end user. That request is evaluated and if it is decided to implement it, the programmer studies the existing code to understand how it works before implementing the change. Testing to make sure the existing functionality is retained and the desired new functionality is added often comprises the majority of the maintenance cost.
Software maintenance is not as well studied as other phases of the software life cycle, despite comprising the majority of costs. Understanding has not changed significantly since the 1980s. Software maintenance can be categorized into several types depending on whether it is preventive or reactive and whether it is seeking to add functionality or preserve existing functionality, the latter typically in the face of a changed environment.
