A new system is about to be developed. Which of the following functions has the highest level of risk?

1. A. Likelihood of failure = 20%; impact value = £100,000
2. B. Likelihood of failure = 10%; impact value = £150,000
3. C. Likelihood of failure = 1%; impact value = £500,000
4. D. Likelihood of failure = 2%; impact value = £200,000

Correct Answer: A
In (B) the product of probability × impact has the value £15,000; in (C) the value is £5,000 and in (D) it is £4,000. The value of £20,000 in (A) is therefore the highest.
