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 ...
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.
Software design usually is directed by goals for the resulting system and involves problem-solving and planning – including both high-level software architecture and low-level component and algorithm design. In terms of the waterfall development process, software design is the activity of following requirements specification and before coding ...
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9126 Software engineering — Product quality was an international standard for the evaluation of software quality.It has been replaced by ISO/IEC 25010:2011.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
The characteristics of good requirements are variously stated by different writers, with each writer generally emphasizing the characteristics most appropriate to their general discussion or the specific technology domain being addressed. However, the following characteristics are generally acknowledged. [8] [9]
Software architecture patterns operate at a higher level of abstraction than software design patterns, solving broader system-level challenges. While these patterns typically affect system-level concerns, the distinction between architectural patterns and architectural styles can sometimes be blurry.
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.
A software design description (a.k.a. software design document or SDD; just design document; also Software Design Specification) is a representation of a software design that is to be used for recording design information, addressing various design concerns, and communicating that information to the design’s stakeholders.
