What is supply maintenance?


MRO (maintenance, repair and operation supplies) can generally be referred to as parts and equipment used in plant’s production process but are not part of the finished goods being produced and sold. Supply maintenance is the management of those parts and is an important part of keeping your operations running smoothly. Poor supply maintenance can lead to repair delays, operational downtime, and unnecessary costs.

In order to ensure that you have the parts and components you need when – or even before – you need them, it is important to have a supply maintenance plan in place. Part of that plan is to have a reliable supplier available for your specific MRO needs.
