Risk assessment determines possible mishaps, their likelihood and consequences, and the tolerances for such events. [1] The results of this process may be expressed in a quantitative or qualitative fashion. Risk assessment is an inherent part of a broader risk management strategy to help reduce any potential risk-related consequences. [1] [2]
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]
Risk is the lack of certainty about the outcome of making a particular choice. Statistically, the level of downside risk can be calculated as the product of the probability that harm occurs (e.g., that an accident happens) multiplied by the severity of that harm (i.e., the average amount of harm or more conservatively the maximum credible amount of harm).
The New York Stock Exchange requires the Audit Committees of its listed companies to "discuss policies with respect to risk assessment and risk management." The related commentary continues: "While it is the job of the CEO and senior management to assess and manage the company’s exposure to risk, the audit committee must discuss guidelines ...
The exposure factor is usually a subjective value that the person assessing risk must define. It is represented in the impact of the risk over the asset, or percentage of asset lost. As an example, if the asset value is reduced two thirds, the exposure factor value is 0.66. If the asset is completely lost, the exposure factor is 1.0.
Risk is the potential of losing something of value, weighed against the potential to gain something of value. Risk hinders the achievement of objective and it has two attributes. Likelihood: Probability of Risk Event (P) Consequences: Impact of Risk Event (I) In Risk based internal auditing two types of risks are considered. Inherent risk
ISO 31000 is a set of international standards for risk management.It was developed in November 2009 by International Organization for Standardization. [1] The goal of these standards is to provide a consistent vocabulary and methodology for assessing and managing risk, resolving the historic ambiguities and differences in the ways risk are described.
Probabilistic risk assessment (PRA) is a systematic and comprehensive methodology to evaluate risks associated with a complex engineered technological entity (such as an airliner or a nuclear power plant) or the effects of stressors on the environment (probabilistic environmental risk assessment, or PERA).
