This Cahier de la sécurité industrielle introduce the concepts and issues related to the use of Risk-informed decisionmaking (RIDM). These are structured processes which assist decision-makers when faced with high impact, complex decisions involving multiple objectives and the presence of uncertainty. They aim to ensure that decisions between competing alternatives are taken with an awareness of the risks associated with each option, and that all attributes of a decision are considered in an integrated manner.
The RIDM processes adopted by NASA and by the US Nuclear Regulatory Commission are described in detail, with an analysis of commonalities and differences in approach.
Objectives
Apprehend the Risk-informed decisionmaking (RIDM).
