CAST Risk-Based Testing Strategies 3

Question 1

When should risk assessment first be performed in a project lifecycle?

Accepted Answer

As early as possible, ideally during planning

Answer

Early risk assessment lets teams plan mitigation and allocate test effort from the start.

Question 2

What does it mean to 'mitigate' a risk through testing?

Accepted Answer

Reduce its likelihood or impact by testing the area thoroughly

Answer

Testing mitigates risk by detecting defects early, lowering the chance of failure in production.

Question 3

A risk register should be treated as which kind of document?

Accepted Answer

A living document updated throughout the project

Answer

Risks change over time, so the register must be reviewed and updated continuously.

Question 4

Which factor most increases the likelihood component of a risk?

Accepted Answer

Use of new or unfamiliar technology

Answer

New or complex technology raises the probability of defects and therefore likelihood of failure.

Question 5

What happens to test priorities when a previously low risk becomes high mid-project?

Accepted Answer

Test effort is reallocated to reflect the new risk level

Answer

Risk-based testing is dynamic; reassessment should trigger reallocation of effort.
