Software Engineering Assessment 3

Question 1

A risk assessment matrix plots risks by severity and what other dimension?

Accepted Answer

Likelihood of occurrence

Answer

A risk matrix maps risks on two axes: severity (impact) and likelihood (probability of occurrence).

Question 2

Which software quality characteristic, as defined by ISO/IEC 25010, refers to a system's ability to be modified efficiently?

Accepted Answer

Maintainability

Answer

ISO/IEC 25010 defines maintainability as the degree to which a system can be modified, corrected, or adapted effectively.

Question 3

In a technical debt assessment, which scenario represents 'deliberate' technical debt?

Accepted Answer

Choosing a quick implementation now with a plan to refactor later

Answer

Deliberate technical debt is a conscious trade-off where a team knowingly takes a shortcut and plans to address it later.

Question 4

What does the 'F-measure' (F1 score) combine when assessing a classifier or test suite?

Accepted Answer

Precision and recall

Answer

The F1 score is the harmonic mean of precision and recall, balancing both metrics for classification performance.

Question 5

An assessment reveals that a codebase has high afferent coupling. What does this indicate about the affected module?

Accepted Answer

Many other modules depend on it

Answer

Afferent coupling (Ca) measures the number of classes outside a module that depend on it, indicating how 'responsible' it is.
