The ISO/IEC 25010 PDF is an for defining software quality requirements, but it is not a standalone measurement guide . Its value lies in the precise, consensus-driven taxonomy of quality attributes. For a quality team, the PDF should be used as the taxonomic foundation , not the implementation manual.

This measures how effectively, efficiently, and satisfactorily the user can achieve their goals.

ISO 9001 addresses quality management systems. ISO/IEC 25010 defines product quality models. They are complementary—use 9001 for processes, 25010 for the quality of the output itself.
