In physics and engineering, the quality factor or Q factor is a dimensionless parameter that describes how underdamped an oscillator or resonator is. It is defined as the ratio of the initial energy stored in the resonator to the energy ...
Functionality, usability, reliability, performance and supportability are together referred to as FURPS in relation to software requirements.
