CAST Risk-Based Testing Strategies 4

Question 1

A defect taxonomy or historical defect data is useful in risk analysis because it helps to:

Accepted Answer

Predict where failures are most likely to recur

Answer

Past defect patterns highlight components that are historically failure-prone and thus higher risk.

Question 2

Which technique uses a structured workshop to rate likelihood and impact for risk items?

Accepted Answer

A risk identification and assessment session

Answer

Collaborative risk sessions systematically score likelihood and impact for each item.

Question 3

What is 'residual risk' after a test cycle?

Accepted Answer

The risk that remains because not everything could be tested or fixed

Answer

Residual risk is the leftover exposure after testing and mitigation efforts conclude.

Question 4

In a risk matrix, an item with high impact and high likelihood falls into which zone?

Accepted Answer

The critical zone requiring the most attention

Answer

High likelihood combined with high impact represents the most critical risk requiring priority focus.

Question 5

Why should risk-based testing results be communicated in business terms?

Accepted Answer

So stakeholders understand the consequences of remaining risks

Answer

Framing risk in business impact helps non-technical stakeholders make informed release decisions.
