ISO IEC 25030:2007 pdfダウンロードSoftware engineering — Software product Quality Requirements and Evaluation (SQuaRE) — Quality requirements
1 Scope
This International Standard provides requirements and recommendations for the specification of softwareproduct quality requirements.
This lnternational Standard applies to organisations in their role as both acquirers and suppliers
The quality model in ISO/IEC 9126-1 ISO/EC 25010] is used to categorize software quality requirements andto provide a basis for quantifying the quality requirements in terms of software quality measures.
This lnternational Standard complies with the technical processes defined in ISO/IEC 15288:2002, which arerelevant for identification of stakeholder product quality needs and for analysis of software product qualityrequirements.
This International Standard does not cover specification of other requirements (such as functionalrequirements, process requirements, business requirements, etc.).
This International Standard does not prescribe specific software quality measures nor does it prescribe anyspecific development process.
2 Conformance
Software quality requirements conform to this lnternational Standard if they fulfil the requirements specified inClause 6.

4 Terms and definitions
For the purposes of this International Standard, the terms and definitions given in ISO/IEC 25000 (repeated in Annex A for convenience) apply. There are no definitions specific to this International Standard.
5 Fundamental concepts for quality requirements
Clause 5 describes concepts related to software quality requirements that are used in this Interna- tional Standard. This clause does not include requirements.
5.1 Software and systems
Software is the main focus of this International Standard. However, software usually appears as part of a larger system. Therefore it can be useful to take a system view. A system is defined as a combination of interacting elements organised to achieve one or more stated purposes. This defini- tion allows a high degree of freedom to decide, what constitute a system and what the elements of the system are.
The boundaries of a system will depend on the point of view. Note 1 The boundary of a system depends on the point of view as illustrated by the following three examples. One example is the control system of an aircraft engine, the second example is the complete engine of an aircraft, and a third example is the complete aircraft. An aircraft can be considered as a combination of ele- ments (the engines, the wings, etc.). These elements can also be considered systems on their own.
