Full title and description
O’z DSt ISO/IEC 9126-1:2008 — Software engineering — Product quality — Part 1: Quality model (Uzbek national adoption of ISO/IEC 9126-1:2001). This document defines a quality model for software products, providing a structured set of quality characteristics and subcharacteristics to be used for evaluation and specification of software product quality.
Abstract
This standard specifies a framework for assessing software product quality. It defines six main quality characteristics (functionality, reliability, usability, efficiency, maintainability and portability) and associated subcharacteristics, providing definitions and guidance for their use in measurement, specification and evaluation activities. The Uzbek national adoption aligns the international ISO/IEC 9126-1 quality model with national standard numbering and publication conventions.
General information
- Status: National adoption of an international standard (adopted standard)
- Publication date: 2008
- Publisher: Uzbekistan national standardization body (national adoption of ISO/IEC)
- ICS / categories: 35.040.99 (Software engineering and related topics)
- Edition / version: 2008 edition (adoption of ISO/IEC 9126-1)
- Number of pages: Typically mirrors original ISO/IEC 9126-1 length (approx. 20–30 pages) — national publication may vary
Scope
The standard establishes a quality model to describe and evaluate the quality of software products. It is intended for use in specifying quality requirements, designing measurement approaches, conducting evaluations, and supporting quality assurance activities. The scope covers the definition of quality characteristics and subcharacteristics, their definitions and relationships, but does not prescribe specific metrics — those are addressed in companion parts of the ISO/IEC 9126 series.
Key topics and requirements
- Definition of six principal software product quality characteristics: functionality, reliability, usability, efficiency, maintainability and portability.
- Breakdown of each characteristic into subcharacteristics (for example: functionality includes suitability, accuracy, interoperability, security, and functionality compliance).
- Terminology and definitions for consistent use in quality specification and assessment.
- Guidance on applying the quality model for requirements specification, measurement planning and product evaluation.
- Recommendation to combine the model with measurement and metrics standards (other parts of ISO/IEC 9126) for quantitative assessment.
Typical use and users
Used by software quality managers, developers, test engineers, system integrators, procurement specialists and standards bodies to define, specify and evaluate software product quality. Useful in contract specifications, quality assurance processes, certification schemes, academic research and tooling that supports quality assessment.
Related standards
ISO/IEC 9126 series parts: Part 2 (external/internal metrics), Part 3 (quality in use metrics). Later superseded by ISO/IEC 25010 (Systems and software Quality Requirements and Evaluation — SQuaRE) and related SQuaRE series (ISO/IEC 2500x). National and industry standards adopting ISO/IEC 9126 or 25010 may also be relevant.

FAQ
Q: What is this standard?
A: It is the Uzbek national adoption of ISO/IEC 9126-1, defining a software product quality model used to describe and evaluate software quality.
Q: What does it cover?
A: It covers the definition of software quality characteristics and subcharacteristics (functionality, reliability, usability, efficiency, maintainability, portability) and guidance on using the model for specification and evaluation. It does not specify detailed metrics.
Q: Who typically uses it?
A: Software quality managers, developers, testers, procurement officers, auditors and researchers use it to specify quality requirements and plan or conduct software quality evaluations.
Q: Is it current or superseded?
A: ISO/IEC 9126-1 has been widely used historically but the ISO/IEC 9126 series has been superseded by the ISO/IEC 25000 SQuaRE series, particularly ISO/IEC 25010 for the quality model. The national 2008 adoption reflects the earlier model; users should consider ISO/IEC 25010 for the latest framework.
Q: Is it part of a series?
A: Yes — it is Part 1 of the ISO/IEC 9126 series (product quality model), with companion parts addressing metrics and quality in use. The series has since been succeeded by the ISO/IEC 25000 SQuaRE series.
Q: What are the key keywords?
A: Software quality, quality model, functionality, reliability, usability, efficiency, maintainability, portability, ISO/IEC 9126.
