Software Engineering Assessment 4

Question 1

A team's post-mortem assessment identifies that most defects were found only during system testing. Which earlier-phase practice would most directly address this?

Accepted Answer

Shift-left testing

Answer

Shift-left testing moves testing activities earlier in the development lifecycle to catch defects sooner and at lower cost.

Question 2

When assessing architectural quality, which pattern violation is described as a high-level module depending on a low-level module directly?

Accepted Answer

Dependency Inversion Principle violation

Answer

The Dependency Inversion Principle states high-level modules should depend on abstractions, not concrete low-level modules.

Question 3

In a usability assessment, a 'think-aloud protocol' requires participants to do what?

Accepted Answer

Verbalize their thoughts while interacting with the system

Answer

The think-aloud protocol captures real-time cognitive processes by having users narrate their thoughts during system interaction.

Question 4

Which measurement model assesses software reliability by tracking failure intervals over time?

Accepted Answer

Software Reliability Growth Model (SRGM)

Answer

SRGMs (like the Jelinski-Moranda model) use observed failure data over time to estimate and predict software reliability.

Question 5

An independent verification and validation (IV&V) assessment differs from standard V&V primarily because it is performed by whom?

Accepted Answer

A party organizationally independent from the development team

Answer

IV&V requires an independent third party to perform verification and validation, ensuring objectivity and avoiding conflicts of interest.
