Risk control, also known as hazard control, is a part of the risk management process in which methods for neutralising or reduction of identified risks are implemented. . Controlled risks remain potential threats, but the probability of an associated incident or the consequences thereof have been significantly red
As applied to finance, risk management concerns the techniques and practices for measuring, monitoring and controlling the market-and credit risk (and operational risk) on a firm's balance sheet, on a bank's credit exposure, or re a fund manager's portfolio value; for an overview see Finance § Risk management. A traditional measure in banking ...
A risk measure is defined as a mapping from a set of random variables to the real numbers. This set of random variables represents portfolio returns. The common notation for a risk measure associated with a random variable X {\displaystyle X} is ρ ( X ) {\displaystyle \rho (X)} .
Governance activities ensure that critical management information reaching the executive team is sufficiently complete, accurate and timely to enable appropriate management decision making, and provide the control mechanisms to ensure that strategies, directions and instructions from management are carried out systematically and effectively.
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 }} .
Hierarchy of hazard control is a system used in industry to prioritize possible interventions to minimize or eliminate exposure to hazards. [ a ] It is a widely accepted system promoted by numerous safety organizations.
Some researchers have criticised control self-assessment as a flawed approach as the way risk is defined and measured is unsophisticated. In particular, control self-assessment may understate risk by not identifying extreme downside risk. An extreme downside risk is a highly improbable event that would have catastrophic consequences if it occurred.
In the initial steps of the risk management process—risk analysis, risk estimation, and risk control—risks are assessed and managed individually. However, in real-life scenarios, multiple less severe risks can combine to create a more severe risk. Therefore, it is essential to adopt an overall risk perspective for the whole medical device.
