Get the most from the ORX Reference Taxonomy

Guidance to help you use the ORX Reference Taxonomy

To help you get the most from the ORX Reference Taxonomy, we've created guidance to go alongside it. The guidance includes examples and provides more detail about the taxonomies and how you can use them.

Understand how to use each taxonomy at your firm

There's separate guidance available for both the Event Type and the Cause and Impact taxonomies. The Event Type Taxonomy guidance gives you an overview of the taxonomy and provides detailed information about each level 1 risk, including examples of level 2 risks and deep dives.

Similarly, the guidance for the Cause and Impact Taxonomy provides more detail on categorising causes and impacts, explores flags and risk themes and gives you practical examples and use cases.

Available individually or buy both and save

In line with our mission to support operational risk management throughout the financial sector, we provide both taxonomies for free. The guidance is available to purchase individually for each taxonomy, or save money by buying them as a package.

What's available?

  • Event Type Taxonomy guidance only - £1,000*
  • Cause and Impact Taxonomy guidance only - £1,000*
  • Both Event Type and Cause and Impact Taxonomy guidance - £1,620*

If you'd like to purchase one or both of the guidance documents, just fill in the form with your details and we'll send you an invoice.

*This price is for firms using the taxonomy to support their own internal operational risk practice. If you are purchasing the taxonomy for commercial use (e.g. as a consultant) please contact for further details on pricing.
