I very much enjoyed your presentation, this is not a question just some discussionm points. I like your use of the dual matrix, 2 simple 10×10 matrices to identify the transistion from green to yellow and from yellow to red for the detection rankings. I am going to think about this some more.
I have done my own evaluation of AP ranking agianst RPN and find that, for me, the AP ranking is less risk averse and so I am not happy with the published AP Ranking table. I have opted for use of the SxO matrix as an instantaneous techncial risk of my design and then using the Detection ranking to define a project risk as a measure of what actions you are prepared to undertake for the SxO value within your project. Incidentally, I am working with the old AIAG defintions of Detection Ranking as they work better for me in this scenario.
Thank you
Phil
