Risk assessment determines possible mishaps, their likelihood and consequences, and the tolerances for such events. [1] [2] 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] [3]
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]
Firefighters are exposed to risks of fire and building collapse during their work.. In simple terms, risk is the possibility of something bad happening. [1] Risk involves uncertainty about the effects/implications of an activity with respect to something that humans value (such as health, well-being, wealth, property or the environment), often focusing on negative, undesirable consequences. [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".
Risk management activities are applied to project management. Project risk is defined by the Project Management Institute (PMI) as, "an uncertain event or condition that, if it occurs, has a positive or negative effect on a project’s objectives." [1]
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.
However, in this case the value at risk becomes equivalent to a mean-variance approach where the risk of a portfolio is measured by the variance of the portfolio's return. The Wang transform function (distortion function) for the Value at Risk is g ( x ) = 1 x ≥ 1 − α {\displaystyle g(x)=\mathbf {1} _{x\geq 1-\alpha }} .
HIA is intended to produce a set of evidence-based recommendations to inform decision-making (Taylor & Quigley 2002, p. 2).HIA seeks to maximise the positive health impacts and minimise the negative health impacts of proposed policies, programs or projects.
