Hi Paul,
Lots of good recommendations already provided here. 14224 is a good start although it takes work to tweak it for industries other than oil and gas, but is a great start.
I'd look at FMEA's you've done and start getting failure modes there, hydraulic cylinder leaks - deteriorated seal.
You can build or buy a library, then start cataloging the root causes from RCA's, deteriorated seal caused by wrong oil- poor oil handling - lack of proper training and instructions. Was this a component, personnel, or training failure? just more for categorizing failures.
There are library solutions out there like those from Idcon, SwainSmith and others, any off the shelf solutions will still require tuning to your use case IMHO.
The key, again my opinion, to getting actionable information from historical data is to make the reporting easy. Having analyzed a ton of work orders I am continually amazed by the lack useful failure codes and work order descriptions, Pump broke- Fixed pump, some of the the more frequent failure causes I've seen None & Other, Blank. Remember keep it simple and build from there. Train your team on using your CMMS, explain why it is important and then hold them accountable for using it properly.
MIL-HDBK-2155 Failure Reporting, Analysis, and Corrective Action Taken gives a good overview of FRACAS. @Ricky Smith has also done some great presentations on this topic.

Subject: Cataloging failure methods, failure modes, root cause types
Kindest greetings to all.
We have a somewhat random collection of historical data of cataloged failures. My goal is to group downtime entries and component replacements into a sensible group of categories. I'm looking for a broadly accepted tree of commonly identified categories of reason for failure, so that we can Pareto our history and identify hot spots.
Ideally, this would be something published as a standard or a spec, like ISO or a Milspec or something, but of course it doesn't have to be.
My interest is in groups of
> Failure modes
> Failure causes
> Root causes
> any similar category by which one might categorize downtime events or failure events
Thanks in advance for your interest
Paul
