Beyond standard compliance: Assessing safety risk through application of the Six ‘C’s

Managing and understanding the risks associated with safety critical systems is an activity that is well supported with process guidance and known tools and techniques, but remains a complex task generally requiring expert support. In this paper an approach to understanding this risk is discussed based on an analysis of a set of emergent properties identified collectively within Arthur D. Little as the /Six Cs The paper considers how such properties may be measured, what specific combinations of property values may mean and how this approach can complement existing project risk assessment approaches.
