CPSA Architecture Evaluation Methods 4

Question 1

What does the 'utility' root node represent at the top of an ATAM utility tree?

Accepted Answer

The overall desirability or value of the system as perceived by its stakeholders

Answer

The utility root node in the ATAM utility tree represents the overall system value from the stakeholder perspective, which is refined into specific quality attributes.

Question 2

Which scenario component describes what triggers the quality attribute response in a quality attribute scenario?

Accepted Answer

Stimulus

Answer

The stimulus is the condition or event that triggers the system's quality attribute response, such as a user request or hardware failure.

Question 3

An architecture evaluation finds that using a shared database between two services improves performance but reduces modifiability. This is an example of a:

Accepted Answer

Tradeoff point

Answer

A tradeoff point is an architectural decision that affects multiple quality attributes in opposing ways, here improving performance while reducing modifiability.

Question 4

Which of the following best defines 'architecture erosion' as a concern in evaluation?

Accepted Answer

The divergence between intended architecture and actual implemented architecture

Answer

Architecture erosion occurs when the implemented system drifts from the intended architecture due to expedient decisions, patch fixes, or poor change control.

Question 5

In the CPSA context, what is the purpose of 'architecture documentation evaluation'?

Accepted Answer

To verify that documentation accurately reflects the as-built architecture and supports communication

Answer

Architecture documentation evaluation checks whether the documentation faithfully represents the actual system and effectively communicates architectural decisions to stakeholders.
