Rework refers to the correction of a product that does not initially meet an entity's minimum quality standards. The corrective work allows the product to then be sold, thereby allowing a business to recover some margin from a product that would otherwise have been scrapped.

Rework can involve many tasks, including the disassembly of a finished product, the replacement of components, reassembly, and repackaging. The cost required to bring a nonconforming product up to a company's standards may be so high that there is little margin left.
