The difference between Corrective and Preventive Action.

Corrective Action is based on a nonconformance event that has happened in the past. Preventive Action is based on preventing a nonconformance event in the future. Both are analogous procedurally, but with the focus as described. Together, Corrective and Preventive Actions—typically referred to as CAPA, are fundamental parts of a continuous improvement program.

Both sub-systems require some type of a log to record each event; a Corrective Action Log and a Preventive Action Log. Each Corrective and Preventive Action will normally have a form that is used to record the details of the activity performed to satisfy the incident; A Corrective Action Request, a Preventive Action Request.
