The totality of attributes of a product that determine its ability to satisfy stated and implied needs when used under specified conditions. [ ISO/IEC 9126-1, ISO/IEC/IEEE 24765 ]
- Internal quality is the totality of characteristics of the software product from an internal view. Internal quality is measured and evaluated against the internal quality requirements. Details of software product quality can be improved during code implementation, reviewing and testing, but the fundamental nature of the software product quality represented by internal quality remains unchanged unless redesigned. [ ISO/IEC 9126-1 ]
- The term ''internal quality'', used in ISO/IEC 14598 to contrast with ''external quality'', has essentially the same meaning as ''quality'' in ISO 8402. [ ISO/IEC 9126-1 ]
