Relationship between software desirable characteristics (right) and measurable attributes (left) Software quality measurement is about quantifying to what extent a system or software possesses desirable characteristics. This can be performed through qualitative or quantitative means or a mix of both.
In software architecture, these attributed are known as "architectural characteristic" or non-functional requirements. Note that it's software architects' responsibility to match these attributes with business requirements and user requirements. Note that synchronous communication between software architectural components, entangles them and ...
A software development methodology is a framework that is used to structure, plan, and control the life cycle of a software product. Common methodologies include waterfall, prototyping, iterative and incremental development, spiral development, agile software development, rapid application development, and extreme programming.
The software quality metrics of coupling and cohesion were invented by Larry Constantine in the late 1960s as part of a structured design, based on characteristics of “good” programming practices that reduced maintenance and modification costs.
When a requirement specifies a software system’s quality attributes; refers to its core features; imposes constraints on it; or defines the environment in which it will run, it is likely to be architecturally significant. See discussion of design vs. architecture under software architecture for additional criteria of architectural significance.
Software quality assurance sets up an organized and logical set of organizational processes and deciding on that software development standards — based on industry best practices — that should be paired with those organizational processes, software developers stand a better chance of producing higher quality software. However, linking ...
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 [1] It may include ensuring conformance to standards or models, such as ISO/IEC 9126 (now superseded by ISO 25010), SPICE or CMMI .
Software Architecture Pattern refers to a reusable, proven solution to a recurring problem at the system level, addressing concerns related to the overall structure, component interactions, and quality attributes of the system. Software architecture patterns operate at a higher level of abstraction than software design patterns, solving broader ...
