The ‘Seen it all’ stream is for you have audit or risk management training or experience.
The content in the ‘Seen it all’ stream assumes that you are familiar with basic concepts and vocabulary, so they are not explained except when there is a common confusion or contentious interpretation to address. That actually happens a lot in risk management.
The ‘Seen it all’ pages also have a lot of references to authoritative sources, especially ISO 31000, and assume that you have access to those sources.
If all that provokes some uncertainty about reaching your objective, you may want to start with the ‘New to this’ stream , where everything is explained without assuming what you know already. There are some links across the streams, but they always open in a separate window.
These are the series and topics that are ready and waiting for you if you’ve Seen it all. There are more in the pipeline.
