ISO 9000 describes quality assurance elements in generic terms that can be applied to any business regardless of the products or services offered. A standard for software life cycle processes and life cycle data. A vocabulary of terms used in software testing. newsletter signup Many organizations around the globe develop and implement different standards to improve the quality needs of their software. A standard for Software Verification and Validation.

ISO-9126 and ISO-14598. "Functionality" is renamed "functional suitability". Attributes are not defined in the standard, as they vary between different software products. Metrics (to control): They are defined and used to provide a scale and method for measurement. The standard provides a framework for organizations to define a quality model for a software product. Interdependence 4. A standard for the format of documents used in different stages of software testing. This standard proposed a framework that describes the usability components and the relationship between them. "Maintainability" has new subcharacteristics of "modularity" (changes in one component have a minimal impact on others) and "reusability"; "changeability" and "stability" are rolled up into "modifiability". The systems come with hardware, software and support. Quality assurance systems are created to help organizations ensure their products and services satisfy customer expectations by meeting their specifications. "Security" is a new characteristic with subcharacteristics of "confidentiality" (data accessible only by those authorized), "integrity" (protection from unauthorized modification), "non-repudiation" (actions can be proven to have taken place), "accountability" (actions can be traced to who did them), and "authenticity" (identity can be proved to be the one claimed). These systems cover a wide variety of activities encompassing a product’s entire life cycle including planning, controlling, measuring, testing and reporting, and improving quality levels throughout the development and manufacturing process. A standard for software quality metrics and methodology. The spiral model suggests a framework activity that addresses customer communication. "Usability" has new subcharacteristics of "user error protection" and "accessibility" (use by people with a wide range of characteristics). In reality, ISO-25000 replaces the two old ISO standards, i.e. adaptability) is further divided into attributes. The above-mentioned quality attributes are further divided into sub-factors, which you can study when you study the standard in detail. Various organizations and groups all around the world build up and set different standards for improving the excellence and user experience of their software. A standard for software quality assurance plans. ISO/IEC 25000:2005 is commonly known as the standard that provides the guidelines for Software Quality Requirements and Evaluation (SQuaRE). By clarifying, then agreeing on the project priorities and subsequently converting abstract priorities (compliance) to measurable values (output data can be validated against schema X with zero intervention), ISO/IEC 9126 tries to develop a common understanding of the project's objectives and goals. Interaction 3 . Internal metrics are those which do not rely on software execution (static measure). There are five types of characteristics for a system. External metrics are applicable to running software. It has been replaced by ISO/IEC 25010:2011.[1].

Compared to 9126, "security" and "compatibility" were added as main characteristics. Part 11 of this standard deals with the extent to which a product can be used by specified users to achieve specified goals with Effectiveness, Efficiency and Satisfaction in a specified context of use. Guide for Software Verification and Validation Plans. Factors (to specify): They describe the external view of the software, as viewed by the users. Ideally, the internal quality determines the external quality and external quality determines quality in use. ISO 25010 has eight product quality characteristics (in contrast to ISO 9126's six), and 31 subcharacteristics.
"Capacity" is added as a subcharactersitic. The scope of application of the quality models includes supporting specification and evaluation of software and software-intensive computer systems from different perspectives by those associated with their acquisition, requirements, development, use, evaluation, support, maintenance, quality assurance and control, and audit. A quality assurance system may be defined as the organizational structure, responsibilities, procedures, processes, and resources for implementing quality management . "Functional completeness" is added as a subcharacteristic, and "interoperability" and "security" are moved elsewhere. The elements of data modeling—data objects, attributes, and relationships— provide the basis for understanding the information domain of a ... No two projects are ever the same.

This standard deals with the following aspects to determine the quality of a software application −, This standard presents some set of quality attributes for any software such as −.
