RAM Risk Management & Mitigation 5

Question 1

When performing a Preliminary Hazard Analysis (PHA), at what stage of the system life cycle is it typically conducted?

Accepted Answer

During early concept or pre-design phase

Answer

PHA is conducted early in the concept/pre-design phase to identify hazards before design decisions are locked in.

Question 2

What is the key distinction between a 'threat' and a 'vulnerability' in risk management?

Accepted Answer

A threat is a potential cause of harm; a vulnerability is a weakness that can be exploited by a threat

Answer

A threat is any potential cause of harm, while a vulnerability is a weakness in a system that the threat can exploit.

Question 3

In reliability block diagrams (RBD), components arranged in series result in a system reliability that is:

Accepted Answer

Equal to the product of all individual component reliabilities

Answer

For series systems, system reliability is the product of individual component reliabilities, always lower than the least reliable component.

Question 4

Which risk response strategy is most appropriate when a risk has a very low probability but an extremely high consequence?

Accepted Answer

Risk avoidance

Answer

High-consequence risks, even with low probability, typically warrant avoidance because the potential impact is too severe to accept.

Question 5

A 'risk register' in RAM project management serves primarily to:

Accepted Answer

Document identified risks, their assessments, owners, and mitigation plans in one central location

Answer

A risk register is the central repository for all identified risks, including probability, impact, owner, and planned response actions.
