Quality Attributes Quality attributes are used in software system. There are several quality attributes that are used in software systems. Depending on what type of software system a client wants, the architect will need to use the correct attributes. A quality attribute measures how a system is sustained and they describe the intended behavior in the environment in which it is used or was built. Performance is an important quality attribute that is needed in all software systems.
Performance Attribute Quality attributes are used in a system in order to perform the necessary functions that are needed within that system. According to "Software Engineering Institute" (2015), "Quality attribute requirements such as those for performance, security, modifiability, reliability, and usability have a significant influence on the software architecture of a system.” (para. Reasoning about Software Quality Attributes). Quality attributes usually go by different names that one could use. For example, constraints, quality goals, quality-of-service, and non-behavioral requirements. There are some quality attributes that are more common than others. They include availability, reliability, usability, performance, maintainability, manageability, and cost. A good example of a quality attribute is performance.
Performance
The quality attribute that was chosen is performance. Performance is considered to be a quality attribute among others. When it comes to performance, users use it for its functionality that the system provides. Although performance is important, a user may choose to use another system that is similar in functionality if that system performs better. To understand the way performance works one needs to understand what performance does. According to "Rational Geek" (2012)," The quality of a system to execute actions within acceptable time periods. This includes the
