Richard,
Thanks for the article. Always nice to promote and share content like this.
For those wanting to use or share or teach with this article, note that the risk matrix, based on Mil-Spec 882D, has the bottom arrow going the wrong direction. Or viewed differently, the severity boxes decrease left to right which is the opposite of most risk matrices.
Also, a safety colleague of mine goes absolutely bonkers when people present frequency/probability/likelihood without a real time domain. For example in the definition chart under “rare” it states “likely to occur some time in the life of an item”. So consider two items with the same consequences, but one has a lifetime of a month and one has a lifetime of ten years. The former has a true frequency 120 times that of the latter which should be viewed as problematic.
Best,
Craig
