Adaptive maintenance refers to the process of modifying software to accommodate changes in its environment or requirements. This can include updates to operating systems, hardware, or other software that the application interacts with. The goal is to ensure that the software continues to function effectively and meets user needs despite these changes. This type of maintenance is essential for keeping applications relevant and operational over time. It helps organizations avoid obsolescence and ensures compatibility with new technologies, thereby extending the lifespan of the software. Adaptive maintenance is a key aspect of software lifecycle management, which includes phases like development, testing, and deployment.
