Communicating selectively

Question 12

How does resilience contribute to risk management in engineering projects?

Accepted Answer

Resilience enables projects to adjust and recover from risks, enhancing overall success.

Answer

Resilience is unrelated to risk management.

Answer

Resilience is a type of risk assessment.

Answer

Risk mitigation eliminates the need for resilience.

Question 13

In risk and benefit analysis, uncertainties play a critical role. What are the potential consequences of neglecting to properly consider uncertainties in such an analysis?
