Which method is used for evaluating software architecture qualities?

The Cost-Benefit Analysis Method (CBAM) is specifically designed to evaluate and prioritize software architecture qualities by assessing the trade-offs between architectural decisions and the associated costs and benefits. In doing so, it provides a structured approach to identifying which architectural qualities—such as performance, security, and maintainability—are most aligned with project goals and stakeholder needs.

CBAM allows stakeholders to make informed decisions about architectural design by quantifying various factors, ultimately leading to a design that meets quality standards while balancing resources effectively. It is particularly useful because it not only examines the software architecture in isolation but also incorporates financial implications, helping teams to justify architectural choices based on their impact on project success.

In contrast, other options like data flow diagramming and UML primarily focus on representing system components and their interactions rather than specifically evaluating software architecture qualities. Entity-relationship diagrams serve an important role in modeling data relationships in a system but do not directly assess architectural qualities. Thus, the unique capacity of CBAM to analyze and prioritize architectural trade-offs makes it the appropriate method for this evaluation.
