Introduction

This part of GB/T 25000 provides a set of measures for the quality characteristics of use (defined in GB/T 25000.10).

Degree (in combination with GB/T 25000.30) is used to specify the quality requirements for use, and (in combination with GB/T 25000.40 and GB/T 25000.41)

Used to measure and evaluate the quality of use.

This section selects quality measures based on practical value. These measures are based on existing practices (eg, Ref. [10]). This

These measures are not comprehensive and detailed, and users of this section are encouraged to improve them when necessary.

Part 22. Using quality measurements

1 Scope

This part of GB/T 25000 defines the quality of use measures for the characteristics defined in GB/T 25000.10-2016.

Used in conjunction with GB/T 25000.10-2016. This part can be combined with GB/T 25000.30, GB/T 25000.40 and GB/T 25000.41

Standards are used in combination and can meet user needs more generally in terms of product or system quality.

This section contains the following.

--- a basic measure set for each quality characteristic used;

--- Explain how to measure the quality of use.

This section provides a set of recommended quality measurements for use with the quality model in GB/T 25000.10-2016.

Degrees, these measures are not comprehensive and detailed.

These measures can be applied to any human-machine system, including both in-use computer systems and as part of the system.

Software Products.

This section does not specify a measurement range that meets the rating or compliance level, as the value of each system or product depends on the context of use.

And the needs of the user.

Some attributes may have a range of ideal values that depend on, for example, the general factors of human cognitive factors rather than the needs of a particular user.

The quality of use measures presented in this section are mainly based on the quality assurance and management of systems and software products based on real-world effects.

use. The primary users of the measurement results are managers of software and system development, acquisition, evaluation or maintenance.

The main users of this section are those who carry out the statute and evaluation activities, including.

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

---Quality management. Systematic inspection of products or computer systems, such as quality of evaluation as quality assurance and quality control

Part of the situation;

---Supply. Contractual behavior of the system, software product or software service provided by the acquirer according to the contract, for example, in the qualification test

The quality of the situation;

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

---Maintenance. Product improvement based on the use of quality measures.

2 Compliance

Any quality requirements specification or quality assessment that complies with this section should.

a) select the quality characteristics and/or sub-characteristics as defined in GB/T 25000.10-2016 for designation or evaluation;

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

Measure, please explain the reasons;

c) select any specific (S) quality measure associated with it;

d) If any quality measures are modified, please state the reasons for each modification;

e) define additional quality measures to be used but not included in this section;
