Service parts management is the main component of a complete strategic service management process that companies use to ensure that right spare part and resources are at the right place (where the broken part is) at the right time.
Spare parts, are extra parts that are available and in proximity to a functional item, such as an automobile, boat, engine, for which they might be used for repair.
A spare part, spare, service part, repair part, or replacement part, is an interchangeable part that is kept in an inventory and used for the repair or refurbishment of defective equipment/units. Spare parts are an important feature of logistics engineering and supply chain management, often comprising dedicated spare parts management systems.
Spare parts are an outgrowth of the industrial development of interchangeable parts and mass production.
Logistics engineering is a field of engineering dedicated to the scientific organization of the purchase, transport, storage, distribution, and warehousing of materials and finished goods. Logistics engineering is a complex science that considers trade-offs in component/system design, repair capability, training, spares inventory, demand history, storage and distribution points, transportation methods, etc., to ensure the "thing" is where it's needed, when it's needed, and operating the way it's needed all at an acceptable cost.
