Safety versus convenience 

Risk based asset management frameworks force us to be systematic in our approach. Multiple layers of defense are commonly applied to mitigate risks down to what we see as an acceptable level. In many cases it will feel like each layer of defense is a layer of inconvenience. 

 

Do we maximize the number of spikes (or layers of protection) to feel safe?


The ALARP principle is often used to evaluate if a certain defense layer is worth the investment. This type of analysis tends to be CAPEX focused. Very cumbersome operations tend to make people invent bypasses that are more convenient. In addition to investment cost, maybe we should also include the effect of the mitigation solution on convenience and how humans react to it, in addition to cost? If people bypass the intended operating procedure – the result of the new risk mitigation investment could be an increase in the overall risk.
