Rams

In engineering, RAMS (reliability, availability, maintainability and safety)^[1][2] is used to characterize a product or system:

• Reliability – as ability to perform a specific function and may be given as design reliability or operational reliability.
• Availability, – as ability to keep a functioning state in the given environment.
• Maintainability – as ability to be timely and easily maintained (including servicing, inspection and check, repair and/or modification).
• Safety – as ability not to harm people, the environment, or any assets during a whole life cycle.
