Is it possible to add the parameter "Non-Detection" for the risk ?
The formula would be : Risk Criticality Level (risque absolu) = Probability (Probabilité) x severity (Gravité) x non-detection.
Maybe, it is possible to replace the attribute "Trust level" (Niveau de confiance) by "Non-detection"
The detection parameter is described in the FMECA methodology (AMDEC in french).
Other question :
What are the existing formulas that has been set in MEGA to calculate the risk criticality (risque absolu) ?
Thank you for your answers.
To summarize you have to implement a (or several) computed attribute(s) on your risks (in the metamodel obviously).
Becauf a macro is attached you can write inside a formula where you are reading properties of your current object or properties of connected or requested objects.
I changed the attribute "Niveau de confiance" in "Détection" and the attribute values and it seems to work.
