From a pedagogical point of view, conducting training exercises based on simulations is considered to be the most immersive way of learning. This chapter formalizes the assessment and observation of participants in crisis management training exercises, both on technical and non‐technical (organizational) aspects. Then, it proposes a general methodo...

This chapter discusses the ways of improving the scripting phase of an exercise conception in order to improve crisis management training and experiential learning. It also focuses on the elaboration of scenarios, which is based on the scenario's central role in implementing, developing and even maintaining skills. A crisis exercise scenario corres...

This chapter provides an overview of the field of crisis management training. In order to prepare the crisis tool and make it efficient, it is necessary to raise awareness about it, test it out and constantly improve it. Training sessions in the field of major risk and crisis management are essential for the actors involved in the crisis. Training...

Serious games and simulation‐based learning exercises are useful training approaches in crisis management. This chapter defines the concept of degrees of training (DOT) for the main human factors involved in crisis management and then to connect them with other parts of a training system. To connect the DOTs, the authors' previous specifications to...

This chapter describes what a good crisis communication is. Among all the digital tools available, Facebook seems to be essential for supporting effective crisis communication because of its large audience and the public's habits of reading and sharing information. To take advantage of the potential of social networks, particularly in terms of diss...

This chapter first focuses on the strategic crisis unit. It is necessary that crisis managers are trained and that crisis management training sessions fully correspond to the needs identified. This requirement is justified by regulatory constraints, and it is also fundamental that decision makers gain experience and strengthen their levels of exper...

This article introduces a tool-equipped method for modeling and simulating behaviors of a Critical Infrastructure (CI) considered here as System of Systems, then evaluating its resilience. The method is based on modelling concepts, languages and tools from Model Based System Engineering (MBSE), System of Systems Engineering (SoSE) and non-functiona...

When major crises occur, organizations face critical concerns, such as stress, uncertainties, need of quick anticipation and better communication. The need of experience implies a regular training of those involved. Serious games and environmental computer-based simulations are useful training tools for people who have to manage a crisis. They are...

Serious games and environmental computer-based simulations can be useful training tools for people who have to act in emergencies. Currently, stakeholders who deal with crises have to make decisions under stress, for example in order to mitigate consequences or avoid negative impacts on high-stake elements.Many factors are critical in a training en...

Lessons learnt from past accidents emphasize that major crisis management's limitations are mainly characterised by collective failures (organizational, behavioural and cognitive), absence and/or maladaptive training of actors (Guarnieri et al., 2015; Heiderich, 2010; Lagadec, 2012). Indeed, the training exercises have limitations such as the asses...

Manager must be prepared to cope with recent crises which are complex, unpredictable, and which need fast decision-making under stress. The improvement of crisis manager’s skills is mainly possible through training which requires efficient simulation scenarios. Scenarios are the chronological synopsis of events that occur during the exercises and w...
