The non-functional aspects are defined and classified in ISO/IEC 25010:2011, “Systems and software engineering -- Systems and software Quality Requirements and Evaluation (SQuaRE) -- System and software quality models”. [4] The functional size of the software, together with the non-functional size of the software, should be used for ...
Within systems engineering, quality attributes are realized non-functional requirements used to evaluate the performance of a system. These are sometimes named architecture characteristics, or "ilities" after the suffix many of the words share. They are usually architecturally significant requirements that require architects' attention. [1]
Broadly, functional requirements define what a system is supposed to do and non-functional requirements define how a system is supposed to be.Functional requirements are usually in the form of "system shall do <requirement>", an individual action or part of the system, perhaps explicitly in the sense of a mathematical function, a black box description input, output, process and control ...
Functional requirements are supported by non-functional requirements (also known as "quality requirements"), which impose constraints on the design or implementation (such as performance requirements, security, or reliability). Generally, functional requirements are expressed in the form "system must do <requirement>," while non-functional ...
Like all non-functional requirements and quality attributes, [6] architecturally significant requirements should be specified SMART. Quality attribute scenarios [2] are one way to achieve the S (specific) and the M (measured) criteria in SMART. The Software Engineering Institute recommends Quality Attribute Workshops for this effort. [7]
Test cases are built around specifications and requirements, i.e., what the application is supposed to do. It uses external descriptions of the software, including specifications, requirements, and designs, to derive test cases. These tests can be functional or non-functional, though usually functional. Specification-based testing may be ...
You can add a table using HTML rather than wiki markup, as described at HTML element#Tables. However, HTML tables are discouraged because wikitables are easier to customize and maintain, as described at manual of style on tables. Also, note that the <thead>, <tbody>, <tfoot>, <colgroup>, and <col> elements are not supported in wikitext.
The Web Hypertext Application Technology Working Group (WHATWG) began work on the new standard in 2004. At that time, HTML 4.01 had not been updated since 2000, [10] and the World Wide Web Consortium (W3C) was focusing future developments on XHTML 2.0.
