Now let’s see how can one measure some Quality Attributes of a product or application. Performance – shows the response of the system to performing certain actions for a certain period of time. Finally, for each Quality Attribute refinement, the team documents at least one scenario that illustrates how the quality attribute requirement is being met. We call these techniques architectural tactics. 6.2 (1.0) Write a concrete quality attribute scenario for Performance. Tradeoff • As a Philosophy Theory • Define Tradeoffs at Beginning o ATAM o Utility Tree (Quality Attribute Metrics) • Architecture should able to balance Attributes 5. 4.4 Quality Attribute Scenarios in Practice. Quality attribute scenarios scenarios, quality attributes, tactics, usage examples and . scenarios, quality attributes, tactics, usage examples and so on) to support SA design and evaluation processes. These attributes can be used for Quality assurance as well as Quality control. Achieving Quality Attributes through Tactics . This corresponds to the scenario table with the six elements properly identified, and a paragraph succinctly describing the scenario. The quality attribute requirements specify the responses of the system that, with a bit of luck and a dose of good planning, realize the goals of the business. General scenarios provide a framework for generating a large number of generic, system-independent, quality-attribute-specific scenarios. Tactics provide an architectural means of adjusting those parameters, which, in turn, can improve the quality-attribute-specific behavior of the resulting system. quality attribute scenarios and architectural tactics. We then discuss why quality attribute models are the missing link and how they can be exploited to derive design fragments from quality attribute requirements. We illustrate the linkage through an example of a garage door opener. Derive system specific scenario; Table serve as a checklist; QUALITY ATTRIBUTES IN PRACTICE. This template is The results of this exercise are documented in a utility tree (see Chapter 3 for a detailed discussion of the Quality Attribute utility tree) using the structure that we are now familiar with: 2-h lecture about quality attribute scenarios that included understanding quality attributes by using the quality attribute scenarios and achieving quality attributes through tactics. Each is potentially but not necessarily relevant to the system you are concerned with. Each attribute can be used to measure product performance. We also provide a simple process of identifying and . We also provide a simple process of identifying and extracting the architectural information from patterns. We now turn to the techniques an architect can use to achieve the required quality attributes. The here described quality attribute are fairly common in nearly all systems, but there exist many other quality attributes that are domain and product specific; Software architects need to be aware of the driving quality attributes―whatever they are! Table 1 presents the first template, which captures the information extracted from patterns. so on) to support SA design and evaluation processes. The contents of the lecture were based on chapters 4 and 5 … The following factors are used to measure Software Development Quality. Interoperability is an attribute of the system or part of the system that is responsible for its operation and the transmission of data and its exchange with other external systems. Identify and describe at least 2 tactics that could be applied for this scenario. This report justifies the tactics for modifiability, using established concepts of coupling, cohesion, and cost motivations as the means of identifying parameters of interest. 12 software architecture quality attributes. 2. , which, IN turn, can improve the quality-attribute-specific behavior of system!
