In the context of software engineering, software quality refers to two related but distinct notions: [citation needed] Software's functional quality reflects how well it complies with or conforms to a given design, based on functional requirements or specifications. [ 1 ]
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] In software architecture, these attributed are known as "architectural characteristic" or non-functional requirements.
Software engineering is a branch of both computer science and engineering focused on designing, developing, testing, and maintaining of software applications. It involves applying engineering principles and computer programming expertise to develop software systems that meet user needs.
ISO/IEC 9126 Software engineering — Product quality was an international standard for the evaluation of software quality.It has been replaced by ISO/IEC 25010:2011. [1]The quality criteria according to ISO 9126
Software quality is defined as meeting the stated requirements as well as customer expectations. [40] Quality is an overarching term that can refer to a code's correct and efficient behavior, its reusability and portability , or the ease of modification. [ 41 ]
Software Architecture Style refers to a high-level structural organization that defines the overall system organization, specifying how components are organized, how they interact, and the constraints on those interactions. Architecture styles typically include a vocabulary of component and connector types, as well as semantic models for ...
Software quality assurance (SQA) is a means and practice of monitoring all software engineering processes, methods, and work products to ensure compliance against defined standards. [1] It may include ensuring conformance to standards or models, such as ISO/IEC 9126 (now superseded by ISO 25010), SPICE or CMMI .
Quality engineering is the discipline of engineering concerned with the principles and practice of product and service quality assurance and control. [1] In software development, it is the management, development, operation and maintenance of IT systems and enterprise architectures with high quality standard.
