Attributes of software that bear on its ability to prevent unauthorized access, whether accidental or deliberate, to programs or data. 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.

Each quality sub-characteristic e. It defines six product quality characteristics and in an annex provides a suggestion of quality subcharacteristics.

An attribute is an entity which can be verified or measured in the software product. The objective of this standard is to provide a framework for the evaluation of software quality.

ISO/IEC 9126

This page was last edited on 12 Septemberat Attributes of software that bear on the capability to re-establish its level of performance and recover the data directly affected in case of a failure and on the time and effort needed for it. On doing so, however, it leaves up to each organization the task of specifying 912-63 its own model.

The subcharacteristics have been moved from the annex to become part of the standard. Information technology – Software quality characteristics and metrics – Part 3: Internal metrics are applicable to a non executable software product during designing and coding in early stage of development process.

This part provides external metrics for measuring software quality characteristics. Attributes of software that bear on the presence and appropriateness of a set of functions for specified tasks.

An external 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 behaviour of the system of which it is a part.

ISO standards by standard number. The standard provides a iiso for organizations to define a quality model for a software product. This part provides internal metrics for measuring software quality characteristics. Information technology – Software quality characteristics and metrics – Part 2: Software product is defined in a broad sense: Attributes of software that bear on the amount of resource used and the duration of such use in performing its function.

Attributes of software that make the software adhere to application related standards or conventions or regulations in laws and similar prescriptions. 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.

Attributes 1926-3 software that bear on the effort needed to install the software in a specified environment. These biases include changing priorities after the start of a project or not having any clear definitions of “success”. External metrics are applicable to an executable software product during testing or operating in later stage of development and after entering to operation process.

Compared to”security” and “compatibility” were added as main characteristics. Use British English Oxford spelling from January Attributes of software that make the software adhere 916-3 standards or conventions relating to portability. This standard stems from the GE model for describing software quality, presented in by McCall et al.

Quality characteristics and 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 1926-3 the product itself, either direct or indirect it is not derived from measures of the behaviour of the system.

Retrieved from ” ied 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.

As a result, the notion of user extends to operators as well as to programmers, which are users of components such as software libraries.

The current standard is under review. Quality-in-use metrics are only available when the final product is used in real conditions.

Attributes of software that bear on opportunity and effort using it in the place of specified other software in the environment of that software. Information technology – Software quality characteristics and metrics – Part 1: Information technology – Software Product Evaluation – Quality characteristics and guidelines for their use – oso There is also a definition of quality in use which defines the user’s view as a result of using the software.
