Varavaihto

Varavaihto (Finnish: vara- “spare, reserve” + vaihto “exchange, swap”) is a term used in Finnish industrial and logistical contexts to describe the practice of exchanging or swapping spare assets to maintain operations and continuity. The concept centers on keeping a pool of spare equipment or components that can be substituted quickly for failed or degraded items, thereby minimizing downtime and service interruption. Varavaihto is not a formal standard; its exact implementation varies by sector and organization but commonly includes stock management, clear swap rules, and post-exchange handling.

In maintenance and operations, varavaihto refers to rotating or swapping out components such as motors, pumps, or electronic boards with spare units during planned downtimes or when faults occur. In logistics, it can describe the exchange of returnable assets or containers as part of an efficient supply chain. In information technology, hot-swapping or quick replacement of hardware with spare nodes is a related practice, aimed at keeping critical services online.

Key benefits include reduced downtime, faster fault isolation, and more predictable maintenance costs; key requirements are reliable spare-part pools, traceability, and agreed service levels. Potential drawbacks include inventory carrying costs and the need for skilled handling.
