''System safety''
Norwegian University of Science and Technology 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
In reliability engineering, the term availability has the following meanings:
* The degree to which a system, subsystem or equipment is in a specified operable and committable state at the start of a mission, when the mission is called for at ...
: Ability to keep a functioning state in the given environment
* Maintainability
Maintainability is the ease of maintaining or providing maintenance for a functioning product or service. Depending on the field, it can have slightly different meanings.
Usage in different fields Engineering
In engineering, maintainability ...
: Ability to be timely and easily maintained (including servicing, inspection and check, repair and/or modification)
* Safety
Safety is the state of being protected from harm or other danger. Safety can also refer to the control of recognized hazards in order to achieve an acceptable level of risk.
Meanings
The word 'safety' entered the English language in the 1 ...
: Ability not to harm people, the environment, or any assets during a whole life cycle.
