The concept of maintenance refers to the systematic practice of preserving and restoring the condition, functionality, and efficiency of equipment, systems, or processes. In various contexts such as manufacturing, information technology, and real estate, maintenance activities can range from simple tasks like cleaning and lubrication to more complex procedures like software updates or machinery overhauls. The goal is to prolong the life of assets, ensure safety, and minimize downtime or disruptions. Maintenance is often categorized into preventive, corrective, and predictive types, each with its specific methods and schedules. Understanding and implementing effective maintenance strategies are critical for the sustainability and competitiveness of businesses and the general well-being of society.
