The Swiss cheese model of accident causation is a model used in risk analysis and risk management. It likens human systems to multiple slices of Swiss cheese , which has randomly placed and sized holes in each slice, stacked side by side, in which the risk of a threat becoming a reality is mitigated by the differing layers and types of defenses ...
Example of risk assessment: A NASA model showing areas at high risk from impact for the International Space Station. Risk management is the identification, evaluation, and prioritization of risks, [1] followed by the minimization, monitoring, and control of the impact or probability of those risks occurring. [2]
A risk management plan is a document to foresee risks, estimate impacts, and define responses to risks. It also contains a risk assessment matrix.According to the Project Management Institute, a risk management plan is a "component of the project, program, or portfolio management plan that describes how risk management activities will be structured and performed".
The U.S. Navy summarizes the time-critical risk management process in a four-step model: [4] 1. Assess the situation. The three conditions of the Assess step are task loading, additive conditions, and human factors. Task loading refers to the negative effect of increased tasking on performance of the tasks.
The risk management process usually occurs in five distinct steps: plan risk management, risk identification, qualitative and quantitative risk analysis, risk response planning, and risk monitoring and control. The central point of risk identification and assessment in risk management is understanding the risk.
A root cause analysis identifies the set of multiple causes that together might create a potential accident. Root cause techniques have been successfully borrowed from other disciplines and adapted to meet the needs of the system safety concept, most notably the tree structure from fault tree analysis, which was originally an engineering technique.

Risk premium is the product of the market price of risk and the quantity of risk, and the risk is the standard deviation of the portfolio. The CML equation is : R P = I RF + (R M – I RF)σ P /σ M. where, R P = expected return of portfolio I RF = risk-free rate of interest R M = return on the market portfolio σ M = standard deviation of the ...
