Abstract

ISO 9126 [243, 244, 245] is a standard which can be used to describe the quality of software systems. It is based on a quality model that is illustrated in part one of the standard [243]. This model distinguishes quality attributes into internal and external attributes. Internal metrics depend on knowledge on the internal details of the respective software. External metrics can be measured without knowing internal details. Furthermore, the quality model introduces characteristics and sub-characteristics which are abstractions of the actual attributes. For example, Usability is an abstraction of Learnability, Understandability, and Operability which each itself again abstracts from the different attributes.
