CPSA Architecture Evaluation Methods 2

Question 1

Which ATAM phase involves presenting the architecture to stakeholders and collecting utility tree inputs?

Accepted Answer

Phase 1 - Evaluation

Answer

Phase 1 of ATAM involves presenting the business drivers, architecture, and generating the utility tree with stakeholders.

Question 2

In the context of architecture evaluation, what does 'sensitivity point' mean?

Accepted Answer

A parameter of one or more components whose variation affects a quality attribute response

Answer

A sensitivity point is an architectural parameter whose variation produces measurable changes in a quality attribute response measure.

Question 3

What is the primary purpose of conducting a Software Architecture Review (SAR)?

Accepted Answer

To identify risks, non-risks, sensitivity points, and tradeoff points early

Answer

A SAR aims to surface architectural risks, non-risks, sensitivity points, and tradeoffs before costly implementation begins.

Question 4

In CBAM (Cost Benefit Analysis Method), what are 'response levels' used for?

Accepted Answer

Expressing different degrees to which a quality attribute scenario is satisfied

Answer

Response levels in CBAM define the spectrum of possible quality attribute values so stakeholders can assign utility and cost to each level.

Question 5

Which of the following best describes a 'non-risk' in ATAM?

Accepted Answer

A good architectural decision that promotes quality attributes even under reasonable changes

Answer

Non-risks are good decisions that will likely not lead to problems even if underlying assumptions change.
