is a corrective action process; = Failure Reporting Analysis, and Corrective Action System. It's just the term used in the reliability field, following steps very similar to an
8D, e.g. recording failure data, analyzing data (root cause analysis), recommending corrective actions, implementing them, and following up to ensure permanence.
If you already have a corrective action process, you should be fine.
p.s. Sorry, I didn't realize until after I posted and did a search that this topic was just discussed several days ago.
