ISTQB Risk-Based Testing Strategies 4

Question 1

In risk-based testing, which group of stakeholders should be MOST involved in risk assessment?

Accepted Answer

A cross-functional group including business analysts, developers, testers, and business owners

Answer

Risk assessment benefits from diverse perspectives; business owners understand impact, developers know complexity, and testers know testability — all contribute to accurate risk ratings.

Question 2

A safety-critical embedded system and a low-volume internal reporting tool both have a 'medium' likelihood score for a defect. Why might the safety-critical system still receive far more testing effort?

Accepted Answer

Because the impact of failure in the safety-critical system is catastrophically higher

Answer

Risk exposure accounts for both likelihood and impact; catastrophic safety consequences dramatically increase the overall risk level even with equal likelihood scores.

Question 3

What is 'risk-based exit criteria' in software testing?

Accepted Answer

Conditions that define when acceptable risk levels have been achieved, allowing testing to stop

Answer

Risk-based exit criteria define the acceptable residual risk threshold; testing continues until the remaining risks are at or below the agreed level.

Question 4

Which of the following is an example of a 'project risk' rather than a 'product risk'?

Accepted Answer

Key developers leaving the project mid-sprint could delay delivery

Answer

Project risks threaten the project's ability to achieve its objectives (schedule, budget, resources), while product risks relate to potential failures in the software itself.

Question 5

How does risk-based testing differ from coverage-based testing in terms of effort allocation?

Accepted Answer

Risk-based testing allocates effort proportional to risk level; coverage-based testing aims for uniform code coverage

Answer

Risk-based testing intentionally concentrates effort on high-risk areas, whereas coverage-based testing aims to achieve a defined level of coverage across all code or requirements uniformly.
