ABSTRACT

This conclusion presents some closing thoughts on the concepts covered in the preceding chapters of this book. The book documents an Integrated Operations scenario that provided the basis for a comparison of two approaches to risk assessment. It approaches the problem described in the scenario from a quantitative risk assessment perspective. The main operational messages are: risk can be assessed by expressing uncertainty regarding the occurrence and severity of events; risk must also include such dimensions as the level of dialogue between stakeholders, the assessor’s understanding of the system being assessed and the performance of the verification process. The book then tackles the problem described in the scenario, but from a Resilience Engineering perspective. The main operational message is in terms of safety management, Resilience Engineering is about the performance of system functions that allow it to be safe; reducing and coping with risk is a normal side effect of a resilient system.
