ISO IEC 25000:2014 pdf download.Systems and software engineering一Systems and software Quality Requirements and Evaluation (SQuaRE)一Guide to SQuaRE
1 Scope
This International Standard provides guidance for the use of the new series of International Standards named Systems and software Quality Requirements and Evaluation (SQuaRE). The purpose of this Guide is to provide a general overview of SQuaRE contents, common reference models and definitions,as well as the relationship among the documents, allowing users of the Guide a good understanding of those series of standards, according to their purpose of use. This International Standard also contains an explanation of the transition process between the old ISO/IEC 9126 and the ISO/IEC 14598 series and SQuaRE.
The SQuaRE series of International Standards is intended for, but not limited to, developers, acquirers and independent evaluators of systems and software products, particularly those responsible for defining systems and software quality requirements and for systems and software product evaluation.
It is recommended that users of SQuaRE as well as ISO/IEC 14598 and ISO/IEC 9126 series of standards also use this International Standard as a guide to execute their tasks.
2 Conformance
There is no particular conformance clause for this document. Users, for their intended use of SQuaRE series of Standards should follow individual conformance clauses stated in each document of the series.
4.23 product
artifact that is produced, is quantifiable, and can be either an end item in itself or a component item [SOURCE: Guide to the Project Management Body of Knowledge (PMBOK) Fourth Edition: 2008]
Note 1 to entry: ISO 9000:2005 defines four agreed generic product categories: hardware (e.g. engine mechanical part); software (e.g. computer program); services [e.g. transport); and processed materials (e.g. lubricant).Hardware and processed materials are generally tangible products, while software or services are generally intangible. Most products comprise elements belonging to different generic product categories. Whether the product is then called hardware, processed material, software, or service depends on the dominant element.Results could be components, systems, software, services, rules, documents, or many other items. The result could in some cases be many related individual results.
4.24 quality in use
degree to which a product or system can be used by specific users to meet their needs to achieve specific goals with effectiveness, efficiency, freedom from risk and satisfaction in specific contexts of use
Note 1 to entry: Before the product is released, quality in use can be specified and measured in a test environment designed and used exclusively by the intended users for their goals and contexts of use, e.g. User Acceptance Testing Environment.
4.25 quality in use measure
measure of the degree to which a product or system can be used by specific users to meet their needs to achieve specific goals with effectiveness, efficiency, freedom from risk, satisfaction and context coverage in specific contexts of use.ISO IEC 25000 pdf download.
