Quality attribute workshops (QAW) provide a method for evaluating the architecture of a software-intensive system during the acquisition phase of major programs. The architecture is evaluated against a number of critical quality attributes, such as availability, performance, security, interoperability, and modifiability. The evaluation is based on test cases that capture questions and concerns ...

The quality of software is achieved during its development. Development teams use various techniques to investigate, evaluate and control potential quality problems in their systems. These “Quality Attribute Techniques” target specific product qualities such as safety or security. This paper proposes a framework to capture important characteristics of these techniques. The framework is intended...

This practice will identify and prioritize the software attributes. Attributes are the quality characteristics of the software being tested. They are independent of the functional aspects, and primarily relate to the architectural structural aspects of a system. Attribute testing is complex and often avoided because it requires innovative testing techniques. However, many of the dissatisfaction...

In contrast to the "designer logic" approach, this paper shows how the attribute-value feature s t ruc tures of uni f ica t ion g r a m m a r and constraints on them can be axiomatized in classical first-order logic, which can express disjunctive and negative constraints. Because only quantifier-free formulae are used in the axiomatization, the satisfiability problem is NPcomplete.
