Maintenance Outsourcing is the practice of hiring an external service provider to manage and perform maintenance activities for an organization. It involves transferring the responsibility of maintenance operations to a third-party provider, who is responsible for the planning, scheduling, and execution of maintenance activities. Maintenance Outsourcing is often used to reduce costs, improve efficiency, and increase the quality of maintenance services. It can also be used to access specialized skills and resources that may not be available in-house. Common maintenance outsourcing services include preventive maintenance, corrective maintenance, predictive maintenance, and asset management.
