註釋Abstract: "This is one of several reports that provide the current status on the work being done by the Software Engineering Institute (SEI[superscript SM]) to understand the relationship between quality requirements and architectural design. The ultimate objective of this work is to provide analysis-based guidance to designers so that the quality attributes of generated designs are more predictable and better understood. Currently, four distinct problems must be solved to achieve that objective: (1) the precise specification of quality attribute requirements, (2) the enumeration of architectural decisions that can be used to achieve desired quality attribute requirements, (3) a means of coupling one quality attribute requirement to the relevant architectural decisions, and (4) a means of composing the relevant architectural decisions into a design. Embodying the solutions to these four problems into a design method that is sensitive to business priorities is an additional problem. This report deals with the third problem -- coupling one quality attribute requirement to architectural decisions that achieve it. This report provides initial evidence that there is, in fact, a systematic relationship between general scenarios, concrete scenarios, architectural tactics, and design fragments. It examines, in detail, two concrete scenarios -- one for performance and one for modifiability -- and describes how to move from each scenario, through tactics, to design fragments that satisfy the scenario."
