1 Scope

This part of GB/T 25000 is based on the characteristics and sub-characteristics defined in GB/T 25000.10-2016, and is specified for the quantitative evaluation system.

Measure the quality of software and software products. The quality measures defined in this section need to be used in conjunction with GB/T 25000.10-2016 and can be linked.

This section contains the following.

--- a basic set of quality measures for each characteristic and sub-characteristic;

--- How to apply the interpretation of software products and system quality measures.

This section gives an appendix to consider the use of quality measures (Appendix B), using quality measures to define product or system quality.

Measure (Appendix C) and a detailed description of the type of measurement (Appendix D).

This section does not set a range of measure values for a rating or compliance level, as these values are based on each system, product

Or the nature of a part of the product, and depends on the software category, integrity level, and user needs. Some properties may have expectations

The range of values. These ranges do not depend on specific user needs, but on general factors such as human cognitive factors.

The quality measures presented in this section are primarily used for quality assurance and system and software product improvements during or after the development life cycle.

The main users in this section are those who implement quality requirements specifications and evaluation activities, including.

---Development. including requirements analysis, specification design, coding, testing, and acceptance activities during the software life cycle;

---Quality management. Systematic inspection of software products or computer systems, for example, when the quality evaluation of a system or software product becomes quality assurance

When part of the certificate, quality control and quality certification;

---Supply. The agreement when providing the system, software product or software service to the acquirer according to the contract signed, for example, in the qualification test

Software quality;

--- Acquisition. Includes product selection and acceptance testing when acquiring or purchasing systems, software products or software services from suppliers;

---Maintenance. Optimization of software products or systems based on quality measurements.

2 Compliance

Any quality requirements specification or quality assessment following this section should.

a) select or evaluate the quality characteristics and/or sub-characterizations defined in GB/T 25000.10-2016;

b) for each characteristic or sub-character selected, all general quality measures (G) defined in Chapter 8 should be used, if not
