Which of the following categories covers unforeseen operational failures?

The category that covers unforeseen operational failures is operational. This category encompasses failures that occur during normal business operations, such as system outages, process disruptions, or other incidents that can affect the organization's ability to deliver services or products. Operational failures can arise from a variety of causes, including system misconfigurations or problems related to the execution of processes, which do not necessarily stem from technical issues or human errors.

The operational category highlights the importance of having robust processes and contingency plans in place to mitigate risks associated with day-to-day operations. While technical failures pertain specifically to issues with hardware or software, and human errors focus on mistakes made by individuals, operational failures look at the broader picture of how processes and systems are managed and can fail unpredictably during execution. Environmental factors might also cause disruptions, but they represent external influences rather than internal operational failures.
