    "body": "The Guide notes that the term carries several meanings. Product characteristics, the degree to which a product has those characteristics, and the processes, tools, and techniques used to achieve them may all be called quality. A more recent definition of product quality is the capability of a software product to satisfy stated and implied needs under specified conditions. The knowledge area discusses the quality-management process and the quality-assurance process separately. Verification and validation, testing, and technical reviews and audits appear under the quality-assurance process.[^s1]\n\n\nThe Guide's top-level topics for this knowledge area are:\n\n- Software Quality Fundamentals\n- Software Quality Management Process\n- Software Quality Assurance Process\n- Software Quality Tools\n\nRelated standards listed in the Guide's appendix include [[work_ieee_90003_2018|ISO/IEC/IEEE 90003:2018]].[^s1]",
