The failure mode may then be charted on a criticality matrix using severity code as one axis and probability level code as the other. For quantitative assessment, modal criticality number is calculated for each failure mode of each item, and item criticality number is calculated for each item. The criticality numbers are computed using the ...
Criticality is the normal operating condition of a nuclear reactor, in which nuclear fuel sustains a fission chain reaction. A reactor achieves criticality (and is said to be critical) when each fission releases a sufficient number of neutrons to sustain an ongoing series of nuclear reactions.
Criticality accidents are divided into one of two categories: Process accidents, where controls in place to prevent any criticality are breached;; Reactor accidents, which occur due to operator errors or other unintended events (e.g., during maintenance or fuel loading) in locations intended to achieve or approach criticality, such as nuclear power plants, nuclear reactors, and nuclear ...
The Criticality Index allows you to identify tasks that are likely to cause delays to the project. [1] [2] By monitoring tasks with a high Criticality Index a project is less likely to be late. If a task has a 100% Criticality Index it means that during the analysis no matter how the task durations varied, the critical path always included the ...
In operations research and engineering, a criticality matrix is a representation (often graphical) of failure modes along with their probabilities and severities. Severity may be classified in four categories, with Level I as most severe or "catastrophic"; Level II for "critical"; Level III for "marginal"; and Level IV for "minor".
A critical friend is a supportive person who can ask difficult questions using critical thinking to judge a situation. [1] The term has its origins in critical pedagogy education reforms in the 1970s and arose out of the self-appraisal activity which is attributed to Desmond Nuttall. [2] One of the most widely used definitions is from 1993,

The critical incident technique (or CIT) is a set of procedures used for collecting direct observations of human behavior that have critical significance and meet methodically defined criteria. These observations are then kept track of as incidents, which are then used to solve practical problems and develop broad psychological principles.
