Risk Measure Propagation through Organisational Network

In this paper we present a risk measurement methodology by incorporating actors´ dependency relationships with each other across the whole organisational model. We argue that any actor associated with a vulnerable actor holds certain degree of vulnerability as a result of its association with the vulnerable actor. The degree of vulnerability becomes more if the actor is associated with more vulnerable actors. Similarly, we argue that any actor associated with a critical actor holds certain degree of criticality as a result of its association with the critical actor. The degree of criticality becomes more if the actor is associated with more critical actors. We believe our novel approach is capable of guiding the analyst to analyse vulnerability and criticality levels that exists among the actors´ interdependencies across the whole organisational model, hence enabling him/her to design or redesign risk aware business processes.
