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).
A risk: A single action, event or hardware component that contributes to an effort's risk. An improvement on the PMI's PMBOK definition of risk management is to add a future date to the definition of a risk. [2] Mathematically, this is expressed as a probability multiplied by an impact, with the inclusion of a future impact date and critical dates.
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).
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 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]
Event chain methodology reduces the risk probability and impact automatically based on the percent of work completed. Advanced analysis can be performed using a Bayesian approach. It is possible to monitor the chance that a project will meet a specific deadline.
Risk analysis involves the use of techniques for prioritizing the risk, determining the probability of the risk, and calculating the impact of the risk. At no point should the project manager or risk manager decide that the total number of identified risks should cause the cancellation of the project.
A Risk register plots the impact of a given risk over of its probability. The presented example deals with some issues which can arise on a usual Saturday-night party.. A risk register is a document used as a risk management tool and to fulfill regulatory compliance acting as a repository [1] for all risks identified and includes additional information [1] about each risk, e.g., nature of the ...
