Uso, the internal quality determines the external quality and external quality determines quality in use. Compared to”security” and “compatibility” were added as main characteristics.

ISO/IEC 9126

Attributes of software that bear on its ability to prevent unauthorized access, whether accidental or deliberate, to programs or data. Attributes are not defined in the standard, as they vary between different software products.

ISO has eight product quality characteristics in contrast to ISO ‘s sixand 31 subcharacteristics. The subcharacteristics have been moved from the annex to become part of the standard.

Quality characteristics and subcharacteristics. Each quality sub-characteristic e.

ESSI-SCOPE Quality Characteristics and their application

Internal metrics are applicable to a non executable software product during designing and coding in early stage of development process. This page was last edited on 12 Septemberat Attributes of software that bear on the effort needed for modification, fault removal or for environmental change.

ISO standards by standard number. This may be done, for example, by specifying target values for quality metrics which evaluates the degree of presence of quality attributes.

ISO 9126: The Standard of Reference

Attributes of software that bear on the effort needed for diagnosis of deficiencies or causes of failures, or for identification of parts to be modified. It defines six product quality characteristics and in an annex provides a suggestion of quality subcharacteristics.

An internal metric is a quantitative scale and measurement method, which can be used for measuring an attribute or characteristic of a software product, derived from the product itself, either direct or indirect it is not derived from measures of the behaviour of the system. The iiso standard is under review. The standard provides a framework for organizations to define a quality model for a software product. This part provides the concepts introduced in the original standard ie a recommended quality model which categorizes software quality in six characteristics, which are further sub-divided into subcharacteristics.

They have been reworded and several new ones added. Use British English Oxford spelling from January List isk International Electrotechnical Commission standards.

Attributes of software that bear on the effort needed to install the software in a specified environment. An attribute is an entity which can be verified or measured in the software product. Information technology – Software quality characteristics and metrics – Part 2: Attributes of software that bear on the presence and appropriateness of a set of functions for specified tasks.

Attributes of software that bear on the opportunity for its adaptation to different specified environments without applying other actions or means than those provided for this purpose for the software considered. Views Read Edit View history. 9126-22 is also a definition of quality in use which defines the user’s view as a result of using the software.

ISO/IEC – Wikipedia

Attributes of software that bear on opportunity and effort using it in the place of specified other software in the environment of that software. From Wikipedia, the free encyclopedia. Attributes of software that bear on its ability to maintain a specified level of performance in case of software faults or of infringement of its specified interface. Attributes of software that bear on response and processing times and on throughput rates in performances its function.

Information technology – Software Product Evaluation – Quality characteristics and guidelines for their use – Quality-in-use metrics are only available when the final product is used in real conditions.

These biases include changing priorities after the start of a project or not having any clear definitions of “success”.

Attributes of kso that bear on the amount of resource used and the duration of such use in performing its function. Information technology – Software quality characteristics and metrics – Part 1: Attributes of software that make the software adhere to standards 9162-2 conventions relating to portability. This standard stems from the GE model for describing software quality, presented in by McCall et al.
