Detailed Explanation
Quality attributes are measurable or observable characteristics that describe how well a system operates. Common examples include performance, scalability, availability, reliability, security, maintainability, testability, and usability.
Architectural decisions usually involve trade-offs among these attributes. For example, adding distributed components may improve independent scalability but increase operational complexity and failure modes.
