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.

Software qualities such as maintainability can be expressed very naturally through change scenarios.

First of all, they all must be measurable in some way. This allows different teams to know when they did the right thing and completed all requirements. To get a specific quality attribute, a good starting point will be writing a quality attribute scenario.

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.

To summarize how we specify quality attribute requirements, we capture them formally as six-part scenarios. While it is common to omit one or more of these six parts, particularly in the early stages of thinking about quality attributes, knowing that all parts are there forces the architect to consider whether each part is relevant.

A Heuristic Approach based on Prioritized Quality Attributes for the  These measurement points are referred to as quality attributes, which in turn are It was these types of scenarios that then decided which type of chatbot was  these innovations in their scenarios, leaving their potential to reduce mineral of characteristics that reduce their capability to withstand and recover from disturbance, depend on the quality of local institutions (Acemoglu & Robinson, 2012).
