MRO (Maintenance, Repair, and Overhaul)
MRO (Maintenance, Repair, and Overhaul) is the discipline of managing installed-base assets across their service life — scheduled maintenance, repair workflows, overhaul events, and the parts and labor inventory that supports them. In PLM, MRO is where the digital thread closes the loop between as-designed, as-built, and as-maintained configurations of a product. Aras absorbed Impresa Software in 2018 to bring native MRO capability into Innovator.
Why it matters
Manufacturers increasingly bid for service revenue alongside product revenue, and that bid only works if PLM can hand off the as-built configuration to MRO and receive field-failure data back. Vendors that treat MRO as a separate product silo lose that loop; vendors that embed MRO inside the PLM platform — as Aras did — make the installed-base data queryable from the same backbone that owns the design.
