This makes it harder to accurately plan and manage sprints. In section 5.2.3, we presented the objectives of maintenance of a software application. Users will often identify bugs and report them. Automated solutions offer an accurate, objective way to measure each program. Maintenance is the act of providing the service of checking, repairing or replacing. Bad code requires a larger effort and costs more to adapt to new requirements. Cookies Policy In other words, maintainability measures the ease and … Put simply, software maintenance is the process where software vendors provide updates, modifications, bug fixes, patches and additional features to existing software solutions to increase performance. In reality, however, a growing portion of developer time is taken up by the second part—maintenance and bug fixing. Software is more easily maintainable if it has high-quality code that is readable and well-documented, so keep good coding practices in mind while your software is still in development. Maintainable software is software that is easy to understand. Poor quality software is harder to maintain. Software maintainability metrics deliver an inexpensive, accurate approach to detecting potential causes of unmaintainable systems. Software is a model of the real world. The longevity of a product depends on a developer’s ability to keep up with maintenance requirements. It is code that can be understood by someone new - or someone that hasn't seen it in a while - with a minimum of effort. Maintainability is defined as the probability of performing a successful repair action within a given time. Also known as availability, reliability, and serviceability – usually for computer-related hardware and … It is important to make corrective changes regularly. Read our white paper to learn how to move from endless reactive software maintenance to a proactive model which anticipates quality issues and focuses on those that matter most: Reactive Software Maintenance: The Silent Killer of Developer Productivity, Software Quality Metrics: Selecting the Right Metrics for Any Project, Software Quality Measurement: 8 Dimensions of Quality and How to Measure Them, Software Maintainability: What it Means to Build Maintainable Software, An Introduction to Software Testing Life Cycle (STLC): Definition and Phases, Software Traceability: Keeping Track of Dev and Test Productivity when WFH, Software Quality Engineering: A Beginner’s Handbook, How to handle maintenance in agile projects, Breaking out of the reactive maintenance model. Software maintenance is a phase in the software development cycle that … What is Software Maintainability? Website Terms of Use While performing maintenance, you can make four types of changes to your software: Maintaining software in an agile project is challenging. Reliability was first practiced in the early start-up days for the National Aeronautics and Space Administration (NASA) when Robert Lusser, working with Dr. Wernher von Braun's rocketry program, developed what is known as \"Lusser's Law\" . Maintainability prediction software tools offer many benefits. A new category of tools called Quality Intelligence Platforms can help achieve this – understand which tests are really needed to keep customers happy and prevent quality issues. Thus, producing software that is easy to maintain may potentially save large costs.
