Quality attribute scenarios serve this purpose. For the same reason that use cases are essential in determining functional requirements, quality attribute scenarios are used to specify quality attribute requirements. A general scenario for the quality attribute of availability, for example, is shown in Figure 4.2. Its six parts are shown, indicating the range of values they can take. From this we can derive concrete, system-specific, scenarios.

Analyze architectural approaches – Analyze each scenario, rating them by priority. desired quality attributes. Most of these methods encourage the use of architectural patterns to develop architectures with known characteristics and apply scenarios to evaluate those architectures for desired quality attributes. We observe an increased awareness of the links that exist among scenarios, quality attributes, and patterns. management related attributes and their relations and trade-offs. 4. Developer-Oriented Quality Attributes and Evaluation Methods, by P. Jönsson This chapter focuses on developer-oriented quality attributes, such as: Maintainability, Reusability, Flexibility and Demonstrability.

Quality attributes scenarios

This report examines the fol-lowing four software quality attributes: performance, dependability, security, and safety. Each attribute has matured (or is maturing) within its own community, each with their own vernacular and point of view. Quality attribute scenarios and architectural tactics are some of the tools available for the creation of an architecture.

This report describes the newly revised QAW (Quality Attribute Workshop) and describes potential uses of the refined scenarios generated during it. A quality attribute scenario has six parts, shown in the schematic: Source of Stimulus : the entity generating the stimulus. Could be an actor, an actuator, a sensor, and so on. QAW Method . The QAW is a facilitated, early intervention method used to generate, prioritize, and refine quality attribute scenarios before the software architecture is completed.
