ISO 25010:2011
The structure of the book is based on the international standard ISO/IEC 25010:2011 (Systems and software engineering — Systems and software Quality Requirements and Evaluation — System and software quality models). This standard defines a quality model for software products and systems with eight primary quality characteristics.
Additionally, the book contains the chapter Quality Illusions, which addresses supposed quality improvements that do not actually represent real improvements or may even be counterproductive.
