Product Quality explained -
ISO/IEC 25010:2011
Functional suitability
Functional correctness
degree to which a product or system provides the correct results with the needed degree of precision
-
-
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
-
Resource utilization
degree to which the amounts and types of resources used by a product or system, when performing its functions, meet requirements
Time behaviour
degree to which the response and processing times and throughput rates of a product or system, when performing its functions, meet requirements
Performance efficiency - is the performance relative to the amount of resources used under stated conditions
Maintainability
Reusability
degree to which an asset can be used in more than one system, or in building other assets
Analysability
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
Modularity
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
Testability
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
Modifiability
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 a product or system can be modified by the intended maintainers
Reliability
Fault tolerance
degree to which a system, product or component operates as intended despite the presence of hardware or software faults
Recoverability
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
Availability
degree to which a system, product or component is operational and accessible when required for use
Maturity
degree to which a system, product or component meets needs for reliability under normal operation
Reliability - is the degree to which a system, product or component performs specified functions under specified conditions for a specified period of time
Portability
Installability
degree of effectiveness and efficiency with which a product or system can be successfully installed and/or uninstalled in a specified environment
Adaptability
degree to which a product or system can effectively and efficiently be adapted for different or evolving hardware, software or other operational or usage environments
Replaceability
degree to which a product can replace another specified software product for the same purpose in the same environment
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
Usability
-
Accessibility
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
-
-
Learnability
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
-
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
Security
Confidentiality
degree to which a product or system ensures that data are accessible only to those authorized to have access
-
Non-repudiation
degree to which actions or events can be proven to have taken place, so that the events or actions cannot be repudiated later
Integrity
degree to which a system, product or component prevents unauthorized access to, or modification of, computer programs or data
-
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
Compatibility
Interoperability
degree to which two or more systems, products or components can exchange information and use the information that has been exchanged
Co-existence
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
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
