In engineering, reliability, availability, maintainability and safety (RAMS) [1] [2] is used to characterize a product or system: Reliability: Ability to perform a specific function and may be given as design reliability or operational reliability; Availability: Ability to keep a functioning state in the given environment
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]
The impact of ILS is often measured in terms of metrics such as reliability, availability, maintainability and testability , and sometimes System Safety (RAMS). ILS is the integrated planning and action of a number of disciplines in concert with one another to assure system availability.
Failure Modes, effects, and Criticality Analysis is an excellent hazard analysis and risk assessment tool, but it suffers from other limitations. This alternative does not consider combined failures or typically include software and human interaction considerations. It also usually provides an optimistic estimate of reliability.

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).
Together with risk assessment and risk management, risk communication aims to reduce foodborne illnesses. Food safety risk communication is an obligatory activity for food safety authorities [73] in countries, which adopted the Agreement on the Application of Sanitary and Phytosanitary Measures. Risk communication also exists on a smaller scale.
Hot swapping of components: CPUs, RAMs, hard disk drives and solid-state drives. Predictive failure analysis to predict which intermittent correctable errors will lead eventually to hard non-correctable errors. Partitioning/domaining of computer components to allow one large system to act as several smaller systems.
