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 level of risk is usually not absolute, it is usually relative to the matrix in which it appears, producing a useful gradation. Avoid using this template for transient situations. The colors are chosen to intuitively reflect situations generally considered negative and undesirable. Do not use this template to describe desirable situations.
Risk is defined as the possibility that an event will occur that adversely affects the achievement of an objective. Uncertainty, therefore, is a key aspect of risk. [10] Risk management appears in scientific and management literature since the 1920s. [11]
LOPA is a risk assessment undertaken on a 'one cause–one consequence' pair. The steps of a LOPA risk assessment are: [4] Identify the consequences, using a risk matrix; Define the risk tolerance criteria (RTC), based on the tolerable/intolerable regions on the risk matrix; Define the relevant accident scenario, e.g. mechanical or human failure
Preliminary risk levels can be selected based on a risk matrix like shown below, based on Mil. Std. 882. [31] The higher the risk level, the more justification and mitigation is needed to provide evidence and lower the risk to an acceptable level. High risk should be indicated to higher level management, who are responsible for final decision ...
In business and project management, a responsibility assignment matrix [1] (RAM), also known as RACI matrix [2] (/ ˈ r eɪ s i /; responsible, accountable, consulted, and informed) [3] [4] or linear responsibility chart [5] (LRC), is a model that describes the participation by various roles in completing tasks or deliverables [4] for a project or business process.
