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

To determine which function has the highest level of risk, you need to calculate the risk associated with each function by considering both the likelihood of failure and the potential impact of that failure. The risk is typically represented as a product of these two factors:

Risk = Likelihood of Failure × Impact Value.

Now, calculating the risk for each function provides the following insights:

• For the first function, the risk is calculated as 20% (or 0.20) multiplied by £100,000, resulting in £20,000.

• The second function's risk is determined by 10% (or 0.10) multiplied by £150,000, leading to a risk of £15,000.

• The third function involves a 1% (or 0.01) likelihood of failure multiplied by £500,000, which results in a risk of £5,000.

• The fourth function's risk is calculated as 2% (or 0.02) multiplied by £200,000, leading to a risk of £4,000.

After calculating the risks, the function with the highest risk is the one with the greatest resultant value from these calculations. In this case, the first function has the highest
