degree to which a product or system provides the correct results with the needed degree of precision
degree to which the functions facilitate the accomplishment of specified tasks and objectives
degree to which the set of functions covers all the specified tasks and user objectives
Functional suitability - is the degree to which a product or system provides functions that meet stated and implied needs when used under specified conditions
Performance efficiency - is the performance relative to the amount of resources used under stated conditions
degree to which the maximum limits of a product or system parameter meet requirements
degree to which the amounts and types of resources used by a product or system, when performing its functions, meet requirements
degree to which the response and processing times and throughput rates of a product or system, when performing its functions, meet requirements
Compatibility - is the degree to which a product, system or component can exchange information with other products, systems or components, and/or perform its required functions, while sharing the same hardware or software environment
degree to which a product can perform its required functions efficiently while sharing a common environment and resources with other products, without detrimental impact on any other product
degree to which two or more systems, products or components can exchange information and use the information that has been exchanged
Usability - is the degree to which a product or system can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use
degree to which users can recognize whether a product or system is appropriate for their needs
degree to which a product or system can be used by specified users to achieve specified goals of learning to use the product or system with effectiveness, efficiency, freedom from risk and satisfaction in a specified context of use
degree to which a product or system has attributes that make it easy to operate and control
degree to which a system protects users against making errors
degree to which a user interface enables pleasing and satisfying interaction for the user
degree to which a product or system can be used by people with the widest range of characteristics and capabilities to achieve a specified goal in a specified context of use
Reliability - is the degree to which a system, product or component performs specified functions under specified conditions for a specified period of time
degree to which a system, product or component meets needs for reliability under normal operation
degree to which a system, product or component is operational and accessible when required for use
degree to which a system, product or component operates as intended despite the presence of hardware or software faults
degree to which, in the event of an interruption or a failure, a product or system can recover the data directly affected and re-establish the desired state of the system
degree to which a product or system protects information and data so that persons or other products or systems have the degree of data access appropriate to their types and levels of authorization
degree to which a product or system ensures that data are accessible only to those authorized to have access
degree to which a system, product or component prevents unauthorized access to, or modification of, computer programs or data
degree to which actions or events can be proven to have taken place, so that the events or actions cannot be repudiated later
degree to which the actions of an entity can be traced uniquely to the entity
degree to which the identity of a subject or resource can be proved to be the one claimed
degree of effectiveness and efficiency with which a product or system can be modified by the intended maintainers
degree to which a system or computer program is composed of discrete components such that a change to one component has minimal impact on other components
degree to which an asset can be used in more than one system, or in building other assets
degree of effectiveness and efficiency with which it is possible to assess the impact on a product or system of an intended change to one or more of its parts, or to diagnose a product for deficiencies or causes of failures, or to identify parts to be modified
degree to which a product or system can be effectively and efficiently modified without introducing defects or degrading existing product quality
degree of effectiveness and efficiency with which test criteria can be established for a system, product or component and tests can be performed to determine whether those criteria have been met
degree of effectiveness and efficiency with which a system, product or component can be transferred from one hardware, software or other operational or usage environment to another
