What type of risk event is characterized as high-impact/low-probability?

The type of risk event characterized as high-impact and low-probability is a one-off high-profile crisis. This classification indicates that while such events do not occur frequently, when they do, they can have severe consequences for an organization. High-profile crises often attract significant media attention and can lead to reputational damage, financial loss, or regulatory scrutiny, making them critical for risk management strategies.

In contrast, the other options represent scenarios less likely to result in severe outcomes. Routine compliance issues and common technical glitches are typically low-impact and often occur regularly, making them manageable within standard operational procedures. A minor operational error, while it can be disruptive, usually does not rise to the level of a crisis impacting the organization profoundly. Thus, the nature of a one-off high-profile crisis distinctly aligns with the criteria of being high-impact yet low-probability, reinforcing the importance of preparedness and strategic response planning for such rare but significant events.
