Systems and software engineering - Systems and software Quality Requirements and Evaluation (SQuaRE) -
Part 51: Requirements for quality of Ready to Use Software Product (RUSP) and instructions for testing
1 Scope
This Part of GB/T 25000 establishes:
a) Quality requirements for Ready to Use Software Product (RUSP);
b) Requirements for test documentation for the testing of RUSP, including test plan, testing description, and test results;
Note 1: The collection of documents for test is called “test documentation”.
c) Instructions for conformity evaluation of RUSP.
It includes also recommendations for safety or business critical Ready to Use Software Product (RUSP).
This Part deals only with providing the user with confidence that the Ready to Use Software Product (RUSP) will perform as offered and delivered. It does not deal with the production realization (including activities and intermediate products, e.g. specifications). The quality system of a supplier is outside the scope of this Part.
This Part is applicable to Ready to Use Software Product (RUSP).
Note 2: Examples of Ready to Use Software Product (RUSP) include but are not limited to text processors, spreadsheets, database control software, graphics packages, software for technical, scientific or real-time embedded functions (e.g. real-time operating systems), human resources management software, sales management, smartphone application, freeware and web software such as generators of websites/pages.
Note 3: Open source software is not part of Ready to Use Software Product (RUSP).
The intended users of this Part include:
a) suppliers when:
1) specifying requirements for a Ready to Use Software Product (RUSP);
2) assessing their own software products against the claimed performance;
3) issuing declarations of conformity (ISO/IEC 17050);
4) applying for certificates or marks of conformity (ISO/IEC Guide 23);
b) certification bodies that may wish to establish a certification scheme (international, regional or national) (ISO/IEC Guide 28);
c) testing laboratories which will have to follow the instructions for testing when testing for a certificate or a mark of conformity (ISO/IEC 17025);
d) accreditation bodies for accrediting registration or certification bodies and testing laboratories;
e) potential acquirers who may:
1) compare the requirements for the intended work task with the information in product descriptions of existing software products;
2) look for certified Ready to Use Software Product (RUSP);
3) check if the requirements are otherwise met;
f) end users who may profit from better software products;
g) organizations:
1) establishing management and engineering environments based on the quality requirements and methods of this Part; and
2) managing and improving their quality processes “and personnel”.
h) regulatory authorities who may require or recommend the requirements of this Part for Ready to Use Software Product (RUSP) used in safety or business-critical applications.
Information on how to use this Part is given in Annex B.
2 Conformance
A Ready to Use Software Product (RUSP) conforms to this Part if:
a) it has the properties specified in Clause 5;
b) it has been tested by producing test documentation that meets the requirements of Clause 6;
c) anomalies found during testing are documented and resolved prior to product release. Anomalies against advertised performance claims must be fixed or the performance claim must be removed. Known anomalies may be considered acceptable if:
1) the anomaly is not a violation of a performance claim; and
2) the supplier has duly considered the nature and the impact of the anomaly on the potential acquirer and deemed it negligible, and has preserved the documentation of the anomalies for future improvement.
Clause 7 and Annex A are optional.
Note: To facilitate the conformity evaluation, requirements of this part are drafted in a way that they are level 3 subclauses (numbered X.X.X.X). Informative notes complete these clauses and can serve as a guide.
