ISO IEC 25040:2011 pdfダウンロード。Systems and software engineering — Systems and software Quality Requirements and Evaluation (SQuaRE) — Evaluation process
1 Scope
This International Standard contains requirements and recommendations for the evaluation of software
product quality and clarifies the general concepts. It provides a process description for evaluating software product quality and states the requirements for the application of this process. The evaluation process can be used for different purposes and approaches. The process can be used for the evaluation of the quality of predeveloped software, commercial-off-the-shelf software or custom software and can be used during or after the development process.
This International Standard establishes the relationship of the evaluation reference model to the SQuaRE documents as well as shows how each SQuaRE document should be used during the activities of the evaluation process.
It is intended for those responsible for software product evaluation and is appropriate for developers, acquirers and independent evaluators of software products. These three different approaches are detailed in ISO/IEC 14598-3, ISO/IEC 14598-4, and ISO/IEC 14598-5.
It is not intended for evaluation of other aspects of software products (such as functional requirements,process requirements, business requirements, etc.).
2 Conformance
Evaluation of software product quality conforms to this International Standard if it complies with the requirements of Clause 6.
3 Normative references
The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
There are no normative references in this document.
4 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
4.1
acquirer
individual or organization that acquires or procures a system, software product or software service from a supplier
NOTE Adapted from ISO/IEC 12207:2008.
4.2
analysis model
algorithm or calculation combining one or more base and/or derived measures with associated decision criteria
4.3
attribute
inherent property or characteristic of an entity that can be distinguished quantitatively or qualitatively by human or automated means
NOTE 1 Adapted from ISO/IEC 15939:2007.
NOTE 2 ISO 9000 distinguishes two types of attributes: a permanent characteristic existing inherently in something;
and an assigned characteristic of a product, process or system (e.g. the price of a product, the owner of a product). The assigned characteristic is not an inherent quality characteristic of that product, process or system.
4.4
attribute for quality measure
attribute that relates to software product itself, to the use of the software product or to its development process
NOTE Attributes for quality measure are used in order to obtain quality measure elements.
4.5
base measure
measure defined in terms of an attribute and the method for quantifying it
NOTE 1 A base measure is functionally independent of other measures.
NOTE 2 Adapted from the International Vocabulary of Basic and General Terms in Metrology, 1993.
[ISO/IEC 15939:2007]
4.6
commercial-off-the-shelf software product
software product defined by a market-driven need, commercially available, and whose fitness for use has been demonstrated by a broad spectrum of commercial users
4.7
context of use
users, tasks, equipment (hardware, software and materials), and the physical and social environments in which a product is used
[ISO 9241-11:1998]
4.8
custom software
software product developed for a specific application from a user requirements specification
4.9
data
collection of values assigned to base measures, derived measures and/or indicators
[ISO/IEC 15939:2007]
4.10
decision criteria
thresholds, targets, or patterns used to determine the need for action or further investigation, or to describe the level of confidence in a given result.
