Adaptive Maintenance refers to the process of modifying software or systems to accommodate changes in the environment or requirements. This type of maintenance ensures that the system remains functional and relevant as external factors, such as technology advancements or regulatory changes, evolve. It involves updating the system's components, interfaces, or configurations without altering its core functionality. By implementing adaptive maintenance, organizations can extend the lifespan of their systems and improve overall performance, ensuring they continue to meet user needs and comply with industry standards or regulations.
