The Quality Attributes are derived from the business goals and drivers, and they are prioritized using the business drivers. The team breaks down each Quality Attribute into Quality Attribute refinements (see later discussion).

A quality attribute scenario is an unambiguous way to specify a testable quality attribute. A quality attribute scenario is composed of six elements (as the following Figure illustrates): Source of Stimulus: An entity capable of creating stimulus (internal or external people, a computer system, etc) A Quality Attribute Scenario is a quality-attribute-specific requirement. There are 6 parts: Source of stimulus (e.g., human, computer system, etc.) Stimulus – a condition that needs to be considered.

They are usually Architecturally Significant Requirements that require architects' attention. Quality Attribute Scenarios 1. Source of stimulus แหล่งกำเนิด หรือต้นเหตุที่่ก่อให้เกิดเหตุการณ์ (event) อาจเป็น คน หรือ ระบบงานก็ได้ 2.

Contains the vocabulary that can be used to write concrete quality attribute scenarios. proach for reasoning about multiple software quality attributes. 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. In Chapter 7, we discuss how to apply these tools in designing an architecture and in building a skeletal system, and how the architecture is reflected in the organizational structure.

Software qualities such as maintainability can be expressed very naturally through change scenarios. The safety quality attribute may be specified by hazard scenarios In [1] the use of scenarios for assessing 2020-11-17 · Scenarios are testable, falsifiable hypotheses about the quality attribute behavior of the system under consideration. Because they have explicit stimuli and responses, we can evaluate a design in terms of how likely it is to support the scenario, and we can take measurements and test a prototype or fully fleshed-out system for whether it satisfies the scenario in practice. Scenarios describe a system's reaction to a stimulus in a certain situation.

This gives hope that, in time, examination of the architectural decisions will yield a basis for models for those quality attributes where the The scenarios are the most important part of the utility tree, the main reason is that the scenarios help us understand the quality attributes needed, and more importantly, by tying the attributes to real instances in the system the scenarios help make these goals both concrete and measurable.
