introduction

This part of GB/T 25000 is intended to define and/or design an initial set of quality measure elements (QME) that can be applied to software products. The entire life cycle is achieved for the purpose of implementing the System and Software Quality Requirements and Evaluation (SQuaRE) standard. This section also gives the design QME or a set of rules that validate existing QME designs. The main purposes of defining and using the Quality Measurement Element (QME) in this section are. --- Provide guidance for organizations to develop and obtain their own QME; ---Improve the consistent use of specific QMEs in order to measure and use attributes related to various product quality characteristics and sub-characteristics; --- A set of feature sets or sub-characteristics for a given product, helping to identify the set of QMEs that are specifically needed to derive all quality measures. QME is a common element of many quality measures. The intended use of this section is to enable users to select and define relevant valid QME to define internal, external, data or use quality measures. Furthermore, these measures can be used but are not limited to quality requirements Definition, product evaluation and quality assessment. Therefore, it is recommended to precede this part of GB/T 25000.20, GB/T 25000.22, GB/T 25000. 23. GB/T 25000.24 and other measurement standards are used or used together with them. Figure 1 depicts the relationship between GB/T 25000.21 and other SQuaRE quality measurement standards. a) GB/T 25000.20---Measurement Reference Models and Guidelines. Provides reference models and guidelines for measuring quality characteristics. b) GB/T 25000.21---Quality measure element. Provides a format for specifying the elements of the quality measure and can be used for construction Several examples of quality measurement elements for building software quality measures. c) GB/T 25000.22---Use quality measurement. provide measures, including correlation measurements using quality characteristics in the mass model function. d) GB/T 25000.23---System and software product quality measurement. provide measures, including quality characteristics in the product quality model Associate measurement functions and quality measure elements. e) GB/T 25000.24---Data quality measurement. Provides measures, including associated measurement functions for quality characteristics in the data quality model Number and quality measure elements.

1 Scope

This part of GB/T 25000 contains the following information. --- Define QME as the relevant requirements for the components of the product quality requirements specification (with examples) (see Tables 1 and 2 of 6.2); Note. Product quality includes system quality, software product quality, data quality, and ultimately system service quality. --- As an example of the initial QME set (see Table A.1); --- Define and quantify the guidelines for QME's product (target entity) attributes (see Appendix B). This section is intended for use by, but not limited to, developers, acquirers, and independent evaluators of products, especially for the purpose of defining product quality requirements. The person responsible for summing up the product evaluation. When the definition is intended to be used to obtain quality measures (eg GB/T 25000.22, GB/T 25000.23, This part is applicable when the QME is related to the quality measures specified in GB/T 25000.24.

2 Compliance

When a user defines a quality measure for a product, each QME referenced shall be an information item in the format specified in Table 1 (see 6.2). Describe. This description should also be applicable to modifying an existing QME.
