Software Testing Risk Assessment & Management 4

Question 1

Which quantitative technique uses repeated random sampling to model the probability distribution of overall project risk?

Accepted Answer

Monte Carlo simulation

Answer

Monte Carlo simulation runs thousands of iterations with random variable inputs to produce a probability distribution of outcomes such as schedule or cost.

Question 2

Failure Mode and Effects Analysis (FMEA) produces a Risk Priority Number (RPN). Which three factors are multiplied to calculate RPN?

Accepted Answer

Severity, Occurrence, Detection

Answer

RPN = Severity × Occurrence × Detection; higher RPNs indicate failure modes that most urgently require corrective action.

Question 3

A software team applies risk-based testing and decides NOT to test a low-risk feature to save time. This decision must be recorded because it represents:

Accepted Answer

An accepted risk that increases residual risk

Answer

Skipping tests for low-risk features is an explicit risk acceptance decision that raises residual risk, and it must be logged in the risk register.

Question 4

In Agile testing, product backlog items are often risk-ordered. What criterion makes an item 'high risk' in this context?

Accepted Answer

Items with unclear requirements and high customer value

Answer

Unclear requirements combined with high business value create both high probability of defects and high impact if those defects reach users.

Question 5

A contingency reserve in a test project budget specifically covers:

Accepted Answer

The cost of known risks that are expected to occur

Answer

Contingency reserves are allocated for identified risks with a quantified probability, whereas management reserves cover truly unknown risks.
