Description
System properties define a system in terms of HOW WELL it can perform (its functions).
Examples of properties often used as the basis for requirements specifications are the so-called “-ilities“, like Reliability, Availability, Maintainability, Serviceability; and also Safety, Security, Readiness, Responsiveness; or physical characteristics of a system like Length, Width, Height, Volume, Mass, Color.
When a System Property is quantified, we speak of a ⌊Requirement⌋.
