What is the difference between a work order and a corrective action?
The two overlap heavily and often describe the same record from different angles. A work order is the maintenance instruction to carry out a task on an asset, with an owner, priority, and due date. A corrective action is the quality term for fixing a specific non-conformance found during an inspection or audit, tracked through to verified closure. In practice a failed checklist item can raise either, and good software links the original finding, the assigned work, and the evidence of completion in one chain. The label matters less than whether the task is owned, dated, and closed with proof rather than left as a note in a report.
