19 - B.3 Six ISO software quality characteristics

Defines six characteristics that describe, with minimal overlap, software quality. These characteristics provide a baseline for further refinement and description of software quality. This Standard is technically identical with, and has been reproduced from, ISO/IEC 9126:1991.

This International Standard defines six characteristics that describe, with minimal overlap, software quality. These characteristics provide a baseline for further refinement and description of software quality. Guidelines describe the use of quality characteristics for the evaluation of software quality.This International Standard does not provide subcharacteristics and metrics, and method for measurement, rating, and assessment. This International Standard adheres to the definition of quality in ISO 8402.NOTE - A proposal for definitions of subcharacteristics is provided for information in annex A.The definition of the characteristics and associated quality evaluation process model in this International Standard are applicable when specifying the requirements for and evaluating the quality of software products throughout their life cycle.Its characteristics may be applicable to every kind of software, including computer programs and data contained in firmware.This International Standard is intended for those associated with acquisition, development, use, support, maintenance, or audit of software.
