The collective set of activities performed on operational software or systems, including correction, improvement, and adaptation. It is categorized into corrective maintenance (fixing initial defects), perfective maintenance (improving performance or adding features), adaptive maintenance (accommodating environmental changes), and preventive maintenance (preventing potential failures). Corrective work tends to peak immediately after launch and declines as improvement requests grow over time.
