CPSA Architecture Evaluation Methods 5

Question 1

What is the primary goal of conducting an architecture evaluation 'early' in the development lifecycle?

Accepted Answer

To identify and mitigate architectural risks before they become costly to fix

Answer

Early evaluation catches high-impact architectural risks when changes are cheapest to make, rather than discovering problems after significant implementation investment.

Question 2

Which of the following is NOT a typical step in the ATAM evaluation process?

Accepted Answer

Writing unit tests for each component

Answer

Writing unit tests is a development activity, not part of the ATAM evaluation process, which focuses on architectural analysis rather than implementation.

Question 3

In architecture evaluation, what does 'stakeholder mapping' help achieve?

Accepted Answer

Identifying all parties with an interest in the architecture and what quality attributes concern them most

Answer

Stakeholder mapping ensures all relevant perspectives and quality attribute concerns are represented in the evaluation, preventing blind spots.

Question 4

Which architecture evaluation approach examines whether an architecture can meet its quality attribute goals by tracing scenarios through architectural elements?

Accepted Answer

Scenario-based evaluation

Answer

Scenario-based evaluation traces quality attribute scenarios through the architecture to assess whether the design supports the required responses.

Question 5

In CBAM, what is a 'utility curve' used to represent?

Accepted Answer

The relationship between a quality attribute response level and the business value (utility) it provides

Answer

A utility curve in CBAM maps quality attribute response levels to their corresponding business utility values, enabling cost-benefit calculations.
