"Information quality" is a measure of the value which the information provides to the user of that information. [1] "Quality" is often perceived as subjective and the quality of information can then vary among users and among uses of the information. Nevertheless, a high degree of quality increases its objectivity or at least the ...
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.
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.
Attribute-driven design [1] [2] (also called ADD or Attribute-driven design method) is a methodology to create software architectures that takes into account the quality attributes of the software. It was previously known as the Architecture Based Design Method (or ABD), but due to trademark issues the name was changed to Attribute-driven ...
MIT has an Information Quality (MITIQ) Program, led by Professor Richard Wang, which produces a large number of publications and hosts a significant international conference in this field (International Conference on Information Quality, ICIQ). This program grew out of the work done by Hansen on the "Zero Defect Data" framework (Hansen, 1991).
Information design is the presentation—placement and prioritization of information in a way that facilitates understanding. Information design is an area of user experience design, meant to display information effectively for clear communication. For websites, information elements should be arranged in a way that reflects the goals and tasks ...
Static layouts allow for more control over the aesthetics, and thorough optimization of space around and overlapping irregular-shaped content than dynamic layouts. In web design, this is sometimes referred to as a fixed width layout; but the entire layout may be scalable in size while still maintaining the original proportions, static placement ...
Newer proposals for quality models such as Squale and Quamoco [85] propagate a direct integration of the definition of quality attributes and measurement. By breaking down quality attributes or even defining additional layers, the complex, abstract quality attributes (such as reliability or maintainability) become more manageable and measurable.
